Class JoinTableDataSource

public class JoinTableDataSource
extends DataSource

The Class JoinTableDataSource is the result of a join operation. Nested joins are supported. To use nested joins set either of leftTableSource or rightTableSource to be a JoinTableDataSource.

Note:

The layer type is determined by the leftTableSource. If the leftTableSource is a table then the resulting JoinTableDataSource is a table. If the leftTableSource is a layer then the resulting JoinTableDataSource is a layer.

For performance reasons it is ideal to have leftTableSource and rightTableSource to point to data source from the same workspace and leftTableKey/rightTableKey indexed.
