public class NativeProcMethod
extends NativeMethod

A NativeProcMethod represents native functions that are wrapped in a RubyProc object. They don't have scoping as normal Procs do and are no closures.

Method Summary

Modifier and Type	Method and Description
IRubyObject	call(ThreadContext context, IRubyObject recv, RubyModule clazz, java.lang.String name, IRubyObject[] args) A default implementation of n-arity, non-block 'call' method, which simply calls the n-arity, block-receiving version with the arg list and Block.NULL_BLOCK.
IRubyObject	call(ThreadContext context, IRubyObject recv, RubyModule clazz, java.lang.String name, IRubyObject[] args, Block block) The minimum 'call' method required for a dynamic method handle.

Description copied from class: DynamicMethod

A default implementation of n-arity, non-block 'call' method, which simply calls the n-arity, block-receiving version with the arg list and Block.NULL_BLOCK.

Overrides:

call in class NativeMethod

Parameters:

context - The thread context for the currently executing thread

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

name - The incoming name used to invoke this method

Returns:

The result of the call

call

public IRubyObject call(ThreadContext context,
                        IRubyObject recv,
                        RubyModule clazz,
                        java.lang.String name,
                        IRubyObject[] args,
                        Block block)

Description copied from class: DynamicMethod

The minimum 'call' method required for a dynamic method handle. Subclasses must impleemnt this method, but may implement the other signatures to provide faster, non-boxing call paths. Typically subclasses will implement this method to check variable arity calls, then performing a specific-arity invocation to the appropriate method or performing variable-arity logic in-line.

Overrides:

call in class NativeMethod

Parameters:

context - The thread context for the currently executing thread

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

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
