Detailed Description

An object representation of a message.

A CPInvocation is an object representation of a message sent to an object.

Definition at line 2 of file CPInvocation.h.

Method Documentation

argumentAtIndex:()

- (id) argumentAtIndex: (CPUInteger)  anIndex

implementation

Returns the argument at the specified index. Arguments 0 and 1 are self and _cmd respectively. Thus, method arguments start at 2.

Parameters

anIndex

the index of the argument to return

Exceptions

CPInvalidArgumentException

if anIndex is greater than or equal to the invocation's number of arguments.

Definition at line 117 of file CPInvocation.j.

encodeWithCoder:()

- (void) encodeWithCoder: (CPCoder)  aCoder

implementation

Writes out the invocation's data to the provided coder.

Parameters

aCoder

the coder to which the data will be written

Provided by category CPInvocation(CPCoding).

Definition at line 187 of file CPInvocation.j.

initWithCoder:()

- (id) initWithCoder: (CPCoder)  aCoder

implementation

Initializes the invocation with data from a coder.

Parameters

aCoder

the coder from which to obtain initialization data

Returns

the initialized invocation

Provided by category CPInvocation(CPCoding).

Definition at line 170 of file CPInvocation.j.

initWithMethodSignature:()

- (id) initWithMethodSignature: (CPMethodSignature)  aMethodSignature

implementation

Initializes the invocation with a provided method signature

Parameters

aMethodSignature

the signature of the method to message

Returns

the initialized invocation

Definition at line 53 of file CPInvocation.j.

invocationWithMethodSignature:()

+ (id) invocationWithMethodSignature: (CPMethodSignature)  aMethodSignature

implementation

Returns a new CPInvocation that represents a message to a method.

Parameters

aMethodSignature

the signature of the method to message

Returns

the new invocation

Definition at line 43 of file CPInvocation.j.

invoke()

- (void) invoke

implementation

Sends the encapsulated message to the stored target.

Definition at line 143 of file CPInvocation.j.

invokeWithTarget:()

- (void) invokeWithTarget: (id)  aTarget

implementation

Sends the encapsulated message to the specified target.

Parameters

the	target to which the message will be sent

Definition at line 152 of file CPInvocation.j.

returnValue()

- (id) returnValue

implementation

Returns the invocation's return value

Definition at line 134 of file CPInvocation.j.

selector()

- (SEL) selector

implementation

Returns the invocation's selector

Definition at line 79 of file CPInvocation.j.

setArgument:atIndex:()

- (void) setArgument: (id)  anArgument atIndex: (CPUInteger)  anIndex

implementation

Sets a method argument for the invocation. Arguments 0 and 1 are self and _cmd.

Parameters

anArgument	the argument to add
anIndex	the index of the argument in the method

Definition at line 106 of file CPInvocation.j.

setReturnValue:()

- (void) setReturnValue: (id)  aReturnValue

implementation

Sets the invocation's return value

Parameters

the	invocation return value

Definition at line 126 of file CPInvocation.j.

setSelector:()

- (void) setSelector: (SEL)  aSelector

implementation

Sets the invocation's selector.

Parameters

the	invocation selector

Definition at line 71 of file CPInvocation.j.

setTarget:()

- (void) setTarget: (id)  aTarget

implementation

Sets the invocation's target

Parameters

aTarget

the invocation target

Definition at line 88 of file CPInvocation.j.

target()

- (id) target

implementation

Returns the invocation's target

Definition at line 96 of file CPInvocation.j.
