GetDefinition Method (Table)

In This Topic

Gets the TableDefinition of this dataset. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

C#
Visual Basic (Declaration)

public new TableDefinition GetDefinition()

Public Shadows Function GetDefinition() As TableDefinition

Return Value

The TableDefinition of this dataset.

Exceptions

Exception	Description
System.InvalidOperationException	This dataset does not have a valid definition.
ArcGIS.Core.Data.Exceptions.GeodatabaseException	A geodatabase-related exception has occurred.

Remarks

This routine will throw an exception if called on a joined table, since there is no underlying datastore for these temporary datasets. IsJoinedTable can be used to determine if this table represents a join.

Example

Getting a Table Definition from a Layer

// GetDefinitionFromLayer - This code works even if the layer has a join to another table
private TableDefinition GetDefinitionFromLayer(FeatureLayer featureLayer)
{
  // Get feature class from the layer
  FeatureClass featureClass = featureLayer.GetFeatureClass();

  // Determine if feature class is a join
  if (featureClass.IsJoinedTable())
  {
    // Get join from feature class
    Join join = featureClass.GetJoin();

    // Get origin table from join
    Table originTable = join.GetOriginTable();

    // Return feature class definition from the join's origin table
    return originTable.GetDefinition();
  }
  else
  {
    return featureClass.GetDefinition();
  }
}
