All Known Implementing Classes:
MapReader

public interface IMapReader
extends Serializable

Provides access to members that support reading a map document.

Remarks

MapReader is a helper coclass that reads the contents of a map document file (.mxd and .pmf). The IMapReader interface provides read-only access to: document information (DocumentInfo), the map object (Map), the number of map objects within the document (MapCount), the page layout object (PageLayout), and the thumbnail image stored in the document.

When To Use

When writing your own custom server object use IMapReader to read an .mxd or .pmf.
