Constructor Detail

MethodExpression

public MethodExpression(ASTInfo astInfo,
                        Expression recordExpression,
                        ClosureType signatureType,
                        FunctionSignature signature,
                        boolean dynamicDispatch,
                        boolean isSuper)

Creates new instance of MethodExpression.

Parameters:
