MethodCall

public MethodCall(Expression expr,
                  String name,
                  ExpressionList args)

Allocates a new method call expression object.

Parameters:

expr - the expression which indicates an object or a class. This may be null for invocation on 'this'.

name - the method name.

args - the argumetns for this method.

MethodCall

public MethodCall(String name,
                  ExpressionList args)

Allocates a new method call expression for 'this'. This is equivalent to:

     new MethodCall( (Expression) null, name, args )
 

Parameters:

name - the method name.

args - the argumetns for this method.

MethodCall

public MethodCall(TypeName type,
                  String name,
                  ExpressionList args)

Allocates a new method call expression object.

Parameters:

name - the method name.

args - the argumetns for this method.
