All Implemented Interfaces:

Inlineable, Named

public class GetModuleClass
extends ProcedureN
implements Inlineable

Special procedure to get the Class of the current module. Since "current module" is defined by lexical scope, this isn't a first-class procedure - it has to be inlined.

Field Detail

getModuleClass

public static final GetModuleClass getModuleClass

A function that returns the class of the current module.

getModuleUri

public static final GetModuleClass getModuleUri

A function that returns the URLPath of the current module. This is "class-resource:" URL (see ResourceStreamHandler), though in immediate mode it gets optimized to a "file:" URL.

getModuleUriDummy

public static final GetModuleClass getModuleUriDummy

A dummy 1-argument functions used in implementing getModuleUri. It takes one argument - a reference to a declaration containing the intended result, with a value to initialize it. The compile method sets up the needed static initialization.

GetModuleClass

public GetModuleClass()

Method Detail

applyN

public Object applyN(Object[] args)

Overrides:

applyN in class Procedure

numArgs

public int numArgs()

Description copied from class: Procedure

Return minArgs()|(maxArgs<<12). We use a single virtual function to reduce the number of methods in the system, as well as the number of virtual method table entries. We shift by 12 so the number can normally be represented using a sipush instruction, without requiring a constant pool entry.

Overrides:

numArgs in class Procedure

compile

public void compile(ApplyExp exp,
                    Compilation comp,
                    Target target)

Specified by:

compile in interface Inlineable

getReturnType

public Type getReturnType(Expression[] args)

Description copied from class: Procedure

Semi-deprecated - instead should be set at Inline time. FIXME

Overrides:

getReturnType in class Procedure

getModuleClassExp

public static Expression getModuleClassExp()

getModuleClassURI

public static Expression getModuleClassURI(Compilation comp)

Return an expression that evaluates to a module-relative URL. This has the Kawa-specific URL scheme "class-resource:" and an associated ClassLoader (using a WeakHashMap). It's used to reference resources located using the compiled class's ClassLoader.

classResourcePath

public static gnu.kawa.io.URLPath classResourcePath(Class clas)
