DataSource Class

Uses

Description

The DataSource class provides properties and methods that allow the user to interact with the data source. A description of how to use the data source can be found here. A description of the contents of the data source can be found here.

Public Properties

Property	Description
DefaultIssuer	Gets or sets the default issuer value for use with Get/Set/Put methods
Editable	A boolean value that indicates if the data source can be modified
FileName	The path and file name of the data source currently loaded into this object
IgnoreEnvelope	Indicates if all Envelopes should always return true for InBounds
IsLoaded	A boolean value that indicates if a data source is currently loaded
WKTForceMatch	Indicates if GeoCalc should try to find an existing ICoordSys that matches the WKT when importing an ICoordSys from WKT
