java.lang.Object

org.jikesrvm.classloader.SpecializedMethod

Direct Known Subclasses:

SpecializedScanMethod

public abstract class SpecializedMethod
extends Object

A method that is specialized across all reference types.

In general as there may not be a 1-1 mapping between objects and the specialized methods this class is responsible for performing the mapping.

Specialized methods must have a static 'invoke' method that matches the given signature and return type.

Method Detail

specializeMethod

public abstract CodeArray specializeMethod(RVMType type)

Parameters:

type - the type whose specialzed method is to be returned

Returns:

the specialized method for the given type.

getSignature

public abstract TypeReference[] getSignature()

Returns:

the method signature of the specialized method's invoke.

getReturnType

compileSpecializedMethod

protected CompiledMethod compileSpecializedMethod(RVMMethod template,
                                                  TypeReference[] specializedParams)

Compile a specialized version of a template method. The template must be a method that matches the signature of this specialized method class. The specialized types are the set of types to tell the compiler to use during specialized compilation. This array must match the length of the array returned from getSignature.

Parameters:

template - The method to use as a template

specializedParams - The known types of the parameters, possibly more refined than in the template

Returns:

The compiled code array.
