Method Detail

call

public IRubyObject call(ThreadContext context,
                        IRubyObject self,
                        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.

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

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

call

public IRubyObject call(ThreadContext context,
                        IRubyObject self,
                        RubyModule klazz,
                        java.lang.String name)

Description copied from class: DynamicMethod

Arity 0, no block

Overrides:

call in class DynamicMethod

dup

public DynamicMethod dup()

Description copied from class: DynamicMethod

Duplicate this method, returning DynamicMethod referencing the same code and with the same attributes. It is not required that this method produce a new object if the semantics of the DynamicMethod subtype do not require such.

Specified by:

dup in class DynamicMethod

Returns:

An identical DynamicMethod object to the target.
