A string naming an Objective-C class or a pointer to an Objective-C foreign object.
A string naming the method to invoke.
The function
can-invoke-p
is used to check whether an Objective-C instance and class method can be invoked (is defined) for a given class. If
class-or-object-pointer
is a string, then it must name an Objective-C class and the class method named
method
in that class is checked. Otherwise
class-or-object-pointer
should be a foreign pointer to an Objective-C object or class and the appropriate instance or class method named
method
is checked. The value of
method
should be a concatenation of the message name and its argument names, including the colons, for example
"setWidth:height:"
.
The return value
flag
is
nil
if the method cannot be invoked and
t
otherwise.
