GPTool

public class Frequency
extends AbstractGPTool

Creates a list of the unique code occurrences and their frequency for a specified set of items in an table. The Frequency tool is contained in the Analysis Tools tool box.

Software restrictions: ArcInfo only

Usage tips:

• The Output Table will contain the field Frequency and the specified frequency field(s) and summary field(s).
• The output table will contain the frequency calculation for each attribute value combination of the specified frequency field(s).
• If a summary field is specified, the unique attribute values of the frequency calculation are summarized by the numeric attribute values of each summary field.
• Current map layers may be used to define the Output Table. When using layers, only the currently selected features are used in the Frequency operation.
• Learn more about working with layers and table views;
• The following environment setting affects this tool: Configuration Keyword;

Constructor Detail

Frequency

public Frequency()

Creates the Frequency tool with defaults.

Initializes the array of tool parameters with the default values specified when the tool was created.

Frequency

public Frequency(Object inTable,
                 Object outTable,
                 Object frequencyFields)

Creates the Frequency tool with the required parameters.

Initializes the array of tool parameters with the values as specified for the required parameters and with the default values for the other parameters.

Parameters:

inTable - Table View | Raster Layer, the table containing the field(s) that will be used to calculate frequency statistics. It can be an INFO or OLE DB table, a dBASE or a VPF table, or a feature class.

outTable - Table, the table that will store the calculated frequency statistics.

frequencyFields - Field, the attribute field or fields that will be used to calculate frequency statistics.
