ESRI Table object.

Remarks

A Table object has one or more columns, referred to as fields, and contains an unordered collection of rows. Each row has for each field exactly one value in the data type of the field.

A Table is a Dataset and properties such as the name of the table, the persistable name object for the table, and the workspace containing the table, may be obtained via the IDataset interface. In relational terms, a Table object represents an RDBMS table or view. In objected-oriented terms, a Table object represents an ObjectClass or a RelationshipClass in a geodatabase. A Table object hands out Row objects which themselves support application callable methods depending on the type of data stored in the table.

The Name property of a Table, accessible via the IDataset interface, returns its fully qualified name. The level of qualification may vary depending on the host DBMS. For example, a table named ‘pipes’, owned by a user named ‘gas’ may be called ‘pipes’ in and Access or File Geodatabase, ‘gas.pipes’ on Oracle and ‘mydb.gas.pipes’ on SQLServer. The ParseTableNamemethod on the ISqlSyntax interface supported by the table’s workspace can be used to split the fully qualified name into its components.

Constructor Detail

Table

public Table(Object obj)
      throws IOException
Construct a Table using a reference to such an object returned from ArcGIS Engine or Server. This is semantically equivalent to casting obj to Table.
Casting to this class from the return value of a method will not work, as this class represents an abstract class in ArcObjects.
*
Table o = (Table)obj; // will not work

Table o = new Table(obj); // Use this constructor instead
* @param obj an object returned from ArcGIS Engine or Server

Throws:
IOException - if there are interop problems Table theTable = (Table) obj;
Method Detail

equals

public boolean equals(Object o)
Compare this object with another

Overrides:
equals in class Object

hashCode

public int hashCode()
the hashcode for this object

Overrides:
hashCode in class Object

createRow

public IRow createRow()
               throws IOException,
                      AutomationException
Creates a row in the database with a system assigned object ID and null property values.

Remarks

The CreateRow method creates a new row in the underlying database with a system assigned object id value. A row object representing the created row is returned to the caller. The row object returned has the system assigned object ID as the value of the OIDField. All other fields are initialized to null values if they can be made null and to built-in default values appropriate to the type of the field if they cannot be made null.

The caller is responsible for setting the desired field values into the row and calling the Store method on the row. If the table represents an object class with subtypes, then it is the caller’s responsibility to set the default subtype code into the row and call the InitDefaultValues method on the row before storing, if that is the desired result. For tables without object behavior, insert cursors offer a more efficient way for inserting new rows.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:
createRow in interface ITable
Returns:
A reference to a com.esri.arcgis.geodatabase.IRow
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

getRow

public IRow getRow(int oID)
            throws IOException,
                   AutomationException
The row from the database with the specified object ID.

Remarks

The GetRow method returns an existing row object, given its object ID value. The caller can query the returned row object for additional object specific interfaces. The retrieved row may be modified; calling Store on the row object after changing it will trigger messages to related objects and will mark the row for committing to the database.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:
getRow in interface ITable
Parameters:
oID - The oID (in)
Returns:
A reference to a com.esri.arcgis.geodatabase.IRow
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

getRows

public ICursor getRows(Object oids,
                       boolean recycling)
                throws IOException,
                       AutomationException
The cursor of rows based on a set of object ids.

Remarks

The GetRows method returns a cursor that may be used to retrieve a set of rows specified by the input array of object id values. See the description of the Search method to understand the meaning of the recycling parameter. It is far more efficient to retrieve a set of rows using the GetRows method than it is to retrieve each individual row using the GetRow method. The retrieved rows may be modified; Store should be called on the row objects after changing them.

The oids parameter should be passed an integer array. For example:

Supported Platforms

Windows, Solaris, Linux

// Get a recycling cursor for the OID array.

int[] oids = new int[] { 10844, 10853, 10871 };

Specified by:
getRows in interface ITable
Parameters:
oids - A Variant (in)
recycling - The recycling (in)
Returns:
A reference to a com.esri.arcgis.geodatabase.ICursor
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

createRowBuffer

public IRowBuffer createRowBuffer()
                           throws IOException,
                                  AutomationException
Creates a row buffer that can be used with an insert cursor.

Remarks

The CreateRowBuffer method creates a new row buffer object in memory and returns it to the caller. No row is created in the database. The returned row buffer does not have an object ID value. The caller can set values into the row buffer and use it as an argument to the InsertRow method on an insert cursor; the latter is obtained by calling the Insert method on the Table.

                        throws IOException,
                               AutomationException
Update the Rows in the database selected by the specified query.

Description

This method will edit the rows matching the query filter's constraints. The values in each row will be replaced with the corresponding field's value in the provided row buffer. The fields being edited should be specified in the query filter's SubFields property. If the row buffer contains null values, and the SubFields property is not properly set, the row's values will be overwritten with the row buffer's null values.

public ICursor ITable_search(IQueryFilter queryFilter,
                             boolean recycling)
                      throws IOException,
                             AutomationException
An object cursor that can be used to fetch row objects selected by the specified query.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Specified by:
ITable_search in interface ITable
Parameters:
queryFilter - A reference to a com.esri.arcgis.geodatabase.IQueryFilter (in)
recycling - The recycling (in)
Returns:
A reference to a com.esri.arcgis.geodatabase.ICursor
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

update

public ICursor update(IQueryFilter queryFilter,
                      boolean recycling)
               throws IOException,
                      AutomationException
Returns a cursor that can be used to update Rows selected by the specified query.

Remarks

The Update method returns an update cursor that can be used to update or delete rows. It offers somewhat faster performance than multiple calls to Store or Delete on row objects fetched using a non-recycling search cursor for tables storing simple rows and simple features. There is no difference in performance for complex objects and features.

When using cursors within an edit session, they should always be scoped to edit operations. In other words, a cursor should be created after an edit operation has begun and should not be used once that edit operation has been stopped or aborted.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:
update in interface ITable
Parameters:
queryFilter - A reference to a com.esri.arcgis.geodatabase.IQueryFilter (in)
recycling - The recycling (in)
Returns:
A reference to a com.esri.arcgis.geodatabase.ICursor
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

insert

public ICursor insert(boolean useBuffering)
               throws IOException,
                      AutomationException
Returns a cursor that can be used to insert new Rows.

Remarks

The Insert method returns an insert cursor that can be used to bulk insert rows. It offers significantly faster performance than multiple calls to CreateRow and Store for tables storing simple rows and simple features (that is, for tables whose CLSID is esriGeoDatabase.Row, esriGeoDatabase.Object, or esriGeoDatabase.Feature).

Insert cursors on tables containing complex objects use the CreateRow and Store methods to achieve polymorphism, and there is no difference in performance in these cases.

When using cursors within an edit session, they should always be scoped to edit operations. In other words, a cursor should be created after an edit operation has begun and should not be used once that edit operation has been stopped or aborted.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:
insert in interface ITable
Parameters:
useBuffering - The useBuffering (in)
Returns:
A reference to a com.esri.arcgis.geodatabase.ICursor
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

select

                            int selOption,
                            IWorkspace selectionContainer)
                     throws IOException,
                            AutomationException
A selection that contains the object ids selected by the specified query.

Remarks

The Select method returns a selection set that holds either row IDs or row objects from the Table depending on the selection option. Multiple selection sets can be created on the same table. It is up to a client application or object to keep a reference on created selections and use them as appropriate. For example, a FeatureLayer creates and uses selections on a FeatureClass (a type of Table).

The selType parameter determines the type of selection set that will be created: an ID set, a snapshot, or a hybrid. See the ISelectionSet interface for a comparison of the three types.

When calling Select the selectionContainer parameter is no longer required. A null value should be passed as this parameter.

The set of properties for the dataset.

Description

The PropertySet property is used to return any additional intrinsic properties (but not metadata properties) that may apply to the dataset. One use of this property is to distinguish between the types of File Geodatabase datafile formats. If called on a Feature Class or Table in a File Geodatabase the Datafile Format property can either be esriFGDBStandardDatafile or esriFGDBCompressedDatafile.

Most datasets do not implement this property and will either raise an error or return a null value if it's called. There are a handful of exceptions that will return property sets; these include the datasets from file geodatabases (as mentioned above) and coverages.

Remarks

Examples of intrinsic properties for which explicit methods exist include the SpatialReference and the Extent methods available on the IGeoDataset interface. In most cases this PropertySet will be empty.

IDataset::PropertySet is not supported for Graph objects such as a Geometric Network.

                      throws IOException,
                             AutomationException
Changes a schema lock.

Remarks

There are two kinds of schema locks: shared and exclusive. Shared schema locks are applied automatically by the geodatabase when accessing a dataset and are removed when all references to the dataset are removed. For this reason, it's not necessary to explicitly apply or remove shared schema locks. There is no limit to the number of shared schema locks a dataset or object can have at any given time.
In contrast to shared schema locks, exclusive schema locks are controlled by the developer or ArcGIS application, such as ArcMap or ArcCatalog. An exclusive lock is used to lock a geodatabase dataset or object from use by others to make the necessary changes to it. An exclusive lock is promoted from a shared lock and demoted back to a shared lock when no longer needed. The presence of additional shared schema locks on a dataset or object prevents an exclusive schema lock from being applied and precludes the ability to make changes to the underlying dataset and its schema while it is in use. Only one exclusive schema lock is allowed per dataset. As opposed to shared schema locks, exclusive schema locks are not applied or removed automatically; it is the responsibility of the developer to apply or remove exclusive schema locks.
Limit the scope of exclusive schema locks to the operation that requires the lock. Gather the necessary information to perform the action, obtain the exclusive lock, make the change, and release the lock. Some examples of operations for which an exclusive schema lock should be obtained include:
  • Modifications to attribute domains, such as adding or removing values from a coded value domain or changing the range for range domains
  • Adding or deleting a field from a feature class or object class
  • Associating a class extension with a feature class
  • Creating a topology, geometric network, network dataset, terrain, schematic dataset, representation, or cadastral fabric on a set of feature classes
  • Any use of the IClassSchemaEdit interface
  • Putting a feature class into and taking it out of load-only mode with the IFeatureClassLoad.LoadOnlyMode method
  • Managing (creating, deleting, or modifying) spatial and attribute indexes
Once the action requiring an exclusive schema lock is complete, the exclusive schema lock must be demoted to a shared lock. This includes when errors are raised during the schema modification, for example, consider the case where a field is being deleted from a feature class. To delete the field, an exclusive schema lock is obtained. However, on the call to DeleteField, an error is thrown; that is, the field being deleted is a required field, such as the ObjectID field. In the handling of the error, the exclusive schema lock must be demoted to a shared lock before proceeding.

Remarks

The ISchemaLockInfo interface is used in concert with ISchemaLock to provide information about a schema lock, for example, whether it is shared or exclusive and for ArcSDE geodatabases, the name of the user who has the lock. Note that there will always be at least one schema lock on the dataset. Also note that by checking the schema locks on a dataset a shared schema lock is applied to the data.
