Specified by:

statementToString in class StatementNode

generate

void generate(ActivationClassBuilder acb,
              MethodBuilder mb)
       throws StandardException

generates a the code.

Overrides:

generate in class QueryTreeNode

Parameters:

acb - the activation class builder for this statement

mb - The method for the method to be built

Throws:

StandardException - thrown if generation fails

makeConstantAction

public ConstantAction makeConstantAction()
