Class Methods | |
(id) | + invocationWithMethodSignature: |
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.
- (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.
anIndex | the index of the argument to return |
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.
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.
aCoder | the coder from which to obtain initialization data |
Definition at line 171 of file CPInvocation.j.
- (id) initWithMethodSignature: | (CPMethodSignature) | aMethodSignature |
Initializes the invocation with a provided method signature
aMethodSignature | the signature of the method to message |
Definition at line 54 of file CPInvocation.j.
+ (id) invocationWithMethodSignature: | (CPMethodSignature) | aMethodSignature |
Returns a new CPInvocation that represents a message to a method.
