  +--edu.mit.sketch.ddlcompiler.ConstraintNode

All Implemented Interfaces:

ASTNode

Direct Known Subclasses:

public abstract class ConstraintNode

extends Object

implements ASTNode

Parsing can be thought of as generating and AST. This class represents a constraint node in such an AST. All legal constraint nodes should extend implement this interface.

Constructor Summary

ConstraintNode()

Method Summary

abstract String[]	getConstraintIdentifiers() Returns a string array consisting of the constraint indentifiers
abstract String	toInstanceMethodCall() The method call string which uses arg*_instance instead of arg*
abstract String	toMethodCall() The method call string.
String	toString() The string representation.
abstract boolean	usesMember(String input_id) Return true if a member variable of this constraint has the same name as the input string.
