prepareExpressions

public void prepareExpressions(ExpressionPreparer preparer)
                        throws DatabaseException

Description copied from interface: StatementTreeObject

Prepares all expressions in this statement tree object by passing the ExpressionPreparer object to the 'prepare' method of the expression.

Specified by:

prepareExpressions in interface StatementTreeObject

Throws:

DatabaseException

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException
