```
public class TraceableJittedMethod
extends DynamicMethod
```
This is the mixed-mode method type. It will call out to JIT compiler to see if the compiler wants to JIT or not. If the JIT compiler does JIT this it will return the new method to be executed here instead of executing the interpreted version of this method. The next invocation of the method will end up causing the runtime to load and execute the newly JIT'd method.

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

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 clazz,
                        java.lang.String name,
                        IRubyObject[] args)
```
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 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

Returns:

The result of the call
