Detailed Description

A function object that sends a given message and a given argument to a given object and returns the result.

The selector is stored in the function object and then is invoked by the function object using the given argument as the object to which to send the message.

Member Function Documentation

+ (id) functorWithSelector:

(SEL)

selector

Create and return an instance of OLMemFun1.

Note:

If OpenStep is present the returned object will be autoreleased before being returned.

Parameters:

selector

the selector to store for future invocation

Returns:

a new functor

- (id) initWithObjectInStream:

(OLObjectInStream *)

stream

Initialize the object.

Each instance variable is read from stream and all other initialization is performed.

Parameters:

stream

the stream from which to read

Returns:

a reference to this object

Reimplemented from OLStreamableFunctor.

- (id) initWithSelector:

(SEL)

selector

Initialize the function object with the given selector.

Parameters:

selector

the selector to store for future invocation

Returns:

a reference to this function object

- (id) performBinaryFunctionWithArg:		(id)	arg1
andArg:		(id)	arg2

Send the stored message to the object referenced by arg1 using arg2 as an additional parameter.

The object returned may or may not be owned by the sender of the message, depending on the nature of the message being sent. No attempt is made by the function object to control memory management of the returned object.

Precondition:

arg1 must respond to the selector passed to the initializer.

Parameters:

	arg1	the object to which to send the message
	arg2	the argument to send along with the message

Returns:

the result of invoking the message. Note that memory management is not controlled by the function object and the question of whether to deallocate the returned object depends on the nature of the message.

Reimplemented from < OLBinaryFunction >.

- (void) writeSelfToStream:

(OLObjectOutStream *)

stream

Write the object to a stream.

All instance variables are written to stream.

Parameters:

stream

the stream to which to write.

Reimplemented from OLStreamableFunctor.
