Description copied from class: DynamicMethod

The minimum 'call' method required for a dynamic method handle. Subclasses must implement this method, but may implement the other signatures to provide faster, non-boxing call paths.

Specified by:

call in class DynamicMethod

Parameters:

context - The thread context for the currently executing thread

self - The 'self' or 'receiver' object to use for this call

klazz - The Ruby class against which this method is binding

name - The incoming name used to invoke this method

args - The argument list to this invocation

block - The block passed to this invocation

Returns:

The result of the call
