java.lang.Object
  org.jruby.runtime.callback.ReflectionCallback

All Implemented Interfaces:

Callback

public class ReflectionCallback

extends java.lang.Object

implements Callback

A wrapper for java.lang.reflect.Method objects which implement Ruby methods.

Constructor Summary

ReflectionCallback(java.lang.Class type, java.lang.String methodName, java.lang.Class[] argumentTypes, boolean isRestArgs, boolean isStaticMethod, Arity arity, boolean fast)

Method Summary

IRubyObject	execute(IRubyObject recv, IRubyObject[] oargs, Block block) Calls a wrapped Ruby method for the specified receiver with the specified arguments.
Arity	getArity() Returns the arity of the wrapped Ruby method.
protected java.lang.Object[]	packageRestArgumentsForReflection(java.lang.Object[] originalArgs) Returns an object array that collects all rest arguments in its own object array which is then put into the last slot of the first object array.

Constructor Detail

ReflectionCallback

public ReflectionCallback(java.lang.Class type,
                          java.lang.String methodName,
                          java.lang.Class[] argumentTypes,
                          boolean isRestArgs,
                          boolean isStaticMethod,
                          Arity arity,
                          boolean fast)

Method Detail

packageRestArgumentsForReflection

protected final java.lang.Object[] packageRestArgumentsForReflection(java.lang.Object[] originalArgs)

Returns an object array that collects all rest arguments in its own object array which is then put into the last slot of the first object array. That is, assuming that this callback expects one required argument and any number of rest arguments, an input of [1, 2, 3] is transformed into [1, [2, 3]].

execute

public IRubyObject execute(IRubyObject recv,
                           IRubyObject[] oargs,
                           Block block)

Calls a wrapped Ruby method for the specified receiver with the specified arguments.

Specified by:

execute in interface Callback

getArity

public Arity getArity()

Returns the arity of the wrapped Ruby method.

Specified by:
