Method Detail

getIRMethod

public IRScope getIRMethod()

getParameterList

public java.util.List<java.lang.String[]> getParameterList()

Specified by:

getParameterList in interface IRMethodArgs

calculateArity

private Arity calculateArity()

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.

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

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.

getFile

public java.lang.String getFile()

Description copied from interface: PositionAware

Get the filename for the method.

Specified by:

getFile in interface PositionAware

Returns:

the filename for the method

getLine

public int getLine()

Description copied from interface: PositionAware

Get the line number for the method.

Specified by:

getLine in interface PositionAware

Returns:

the line number for the method
