                                     throws WTException

Returns a WhereExpression for the specified source and target classes.

Supported API: false

Specified by:

buildWhereExpression in interface JoinDelegate

Parameters:

a_sourceClass - Source class of the join (i.e. the class containing the referencing column(s)).

a_targetClass - Target class of the join (i.e. the class that is referenced).

a_sourceIndex - Index of the source class

a_targetIndex - Index of the target class

a_sourceFromAlias - From alias for the source class.

a_targetFromAlias - From alias for the target class.

a_sourceOuterJoin - Indicates if the source side of the join expression should be made an outer join

a_targetOuterJoin - Indicates if the target side of the join expression should be made an outer join

a_referenceName - Reference column name (i.e. query name) in the source class

Returns:

WhereExpression

Throws:

WTException
