Method Detail

call

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

Description copied from class: DynamicMethod

The minimum 'call' method required for a dynamic method handle. Subclasses must implement 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

klazz - The Ruby class against which this method is binding

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.

isSame

public boolean isSame(DynamicMethod method)

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.

getFile

public 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

getSignature

public Signature getSignature()

Description copied from interface: IRMethodArgs

Get the Signature for this method.

Specified by:

getSignature in interface IRMethodArgs

getArgumentDescriptors

public ArgumentDescriptor[] getArgumentDescriptors()

Description copied from interface: IRMethodArgs

Get the array of ArgumentDescriptors that represent the arguments to this method.

Specified by:

getArgumentDescriptors in interface IRMethodArgs

getProc

public RubyProc getProc()
