Method Detail

init

public void init(java.lang.Object newValue)
          throws StandardException

Initializer for a SQLBooleanConstantNode.

Specified by:

init in interface Node

Overrides:

init in class QueryTreeNode

Parameters:

newValue - A String containing the value of the constant: true, false, unknown

Throws:

StandardException

generateConstant

void generateConstant(ExpressionClassBuilder acb,
                      MethodBuilder mb)
                throws StandardException

This generates the proper constant. It is implemented by every specific constant node (e.g. IntConstantNode).

Specified by:

generateConstant in class ConstantNode

Parameters:

acb - The ExpressionClassBuilder for the class being built

mb - The method the expression will go into

Throws:

StandardException - Thrown on error
