Method Documentation

- (id) argumentAtIndex:

(unsigned)

anIndex

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 118 of file CPInvocation.j.

- (void) encodeWithCoder:

(CPCoder)

aCoder

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

Parameters:

aCoder

the coder to which the data will be written

Definition at line 188 of file CPInvocation.j.

- (id) initWithCoder:

(CPCoder)

aCoder

Initializes the invocation with data from a coder.

Parameters:

aCoder

the coder from which to obtain initialization data

Returns:

the initialized invocation

Definition at line 171 of file CPInvocation.j.

- (id) initWithMethodSignature:

(CPMethodSignature)

aMethodSignature

Initializes the invocation with a provided method signature

Parameters:

aMethodSignature

the signature of the method to message

Returns:

the initialized invocation

Definition at line 54 of file CPInvocation.j.

+ (id) invocationWithMethodSignature:

(CPMethodSignature)

aMethodSignature

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 44 of file CPInvocation.j.

- (void) invoke

Sends the encapsulated message to the stored target.

Definition at line 144 of file CPInvocation.j.

- (void) invokeWithTarget:

(id)

aTarget

Sends the encapsulated message to the specified target.

Parameters:

the	target to which the message will be sent

Definition at line 153 of file CPInvocation.j.

- (id) returnValue

Returns the invocation's return value

Definition at line 135 of file CPInvocation.j.

Returns the invocation's selector

Definition at line 80 of file CPInvocation.j.

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

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 107 of file CPInvocation.j.

- (void) setReturnValue:

(id)

aReturnValue

Sets the invocation's return value

Parameters:

the	invocation return value

Definition at line 127 of file CPInvocation.j.

- (void) setSelector:

(SEL)

aSelector

Sets the invocation's selector.

Parameters:

the	invocation selector

Definition at line 72 of file CPInvocation.j.

- (void) setTarget:

(id)

aTarget

Sets the invocation's target
