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

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.

getArity

public Arity getArity()
Description copied from class: DynamicMethod
Retrieve the arity of this method, used for reporting arity to Ruby code. This arity may or may not reflect the actual specific or variable arities of the referenced method.

Overrides:
getArity in class DynamicMethod
Returns:
The arity of the method, as reported to Ruby consumers.

getRealMethod

public DynamicMethod getRealMethod()
Description copied from class: DynamicMethod
Get the "real" method contained within this method. This simply returns self except in cases where a method is wrapped to give it a new name or new implementation class (AliasMethod, WrapperMethod, ...).

Overrides:
getRealMethod in class DynamicMethod
Returns:
The "real" method associated with this one
