public IRubyObject call(ThreadContext context, IRubyObject self, RubyModule klazz, String name, IRubyObject[] args)

Overrides org.jruby.internal.runtime.methods.DynamicMethod.call.

Doc from org.jruby.internal.runtime.methods.DynamicMethod.call.

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.

Parameters

context:ThreadContext: The thread context for the currently executing thread
self:IRubyObject: The 'self' or 'receiver' object to use for this call
klazz:RubyModule: The Ruby class against which this method is binding
name:String: The incoming name used to invoke this method
args:IRubyObject[]: The first argument to this invocation

Returns:IRubyObject

The result of the call
