public class NativeAnonymousMethod

extends NATByRef

implements ATMethod

A NativeAnonymousMethod represents the meta_apply method of an anonymous NativeClosure subclass. An anonymous native method has the following properties: - name = "nativelambda" (to distinguish it from 'ordinary' lambdas) - arguments = [ \@args ] (it takes an arbitrary number of arguments) - body = "Native implementation in {class}" (a string telling an inspector that this closure is natively implemented in the given Java class) - applying a nativelambda directly (without going through this NativeClosure) results in an error

Constructor Detail

NativeAnonymousMethod

public NativeAnonymousMethod(java.lang.Class creatorClass)

Parameters:

creatorClass - class of the object that has created the NativeClosure that will wrap this

Method Detail

base_apply

public ATObject base_apply(ATTable arguments,
                           ATContext ctx)
                    throws InterpreterException

It is an error to directly apply an anonymous method. The closure must be applied instead.

Specified by:

base_apply in interface ATMethod

Parameters:

arguments - the actual arguments, already eagerly evaluated

ctx - the context in which to evaluate the method body, call frame not yet inserted

Returns:

the value of evaluating the method body in a context derived from the given context

Throws:

XIllegalApplication - because an anonymous method must be applied through its wrapping closure.

InterpreterException

base_applyInScope

public ATObject base_applyInScope(ATTable arguments,
                                  ATContext ctx)
                           throws InterpreterException

Description copied from interface: ATMethod

Applies the method to the given arguments in the given context. The context is usually supplied by a closure and is necessary in order to pair a method with its current receiver (its 'self') The method will use the given context 'as-is', and will *not* insert an additional call frame.

Specified by:

base_applyInScope in interface ATMethod

Parameters:

arguments - the actual arguments, already eagerly evaluated

ctx - the context in which to evaluate the method body, to be used without inserting a call frame

Returns:

the value of evaluating the method body in the given context

Throws:

InterpreterException

base_getName

public ATSymbol base_getName()

Description copied from interface: ATMethod

Structural access to the name of the method. Note that all methods (defined using def name( ...args... ) { ... } of def foo: arg bar: arg { ... }) retain the name with which they were first bound. Literal blocks which may be created outside of a definition are implicitly named 'lambda'.

Specified by:

base_getName in interface ATMethod

base_getParameters

public ATTable base_getParameters()

Description copied from interface: ATMethod

Structural access to the parameter list of the method, which is normally a table of symbols.

Specified by:

base_getParameters in interface ATMethod

base_getBodyExpression

public ATBegin base_getBodyExpression()

Description copied from interface: ATMethod

Structural access to the body of the method.

Specified by:

base_getBodyExpression in interface ATMethod

meta_print

public NATText meta_print()
                   throws InterpreterException

Description copied from interface: ATObject

Prints out the object in a human-readable way.

Specified by:

meta_print in interface ATObject

Overrides:

meta_print in class NATNil

Throws:

InterpreterException

meta_getStripes

public ATTable meta_getStripes()
                        throws InterpreterException

Description copied from interface: ATObject

Returns the stripes of this object. Note that only the stripes that were attached directly to this object are returned, not all of the parent's stripes as well.

Specified by:

meta_getStripes in interface ATObject

Overrides:

meta_getStripes in class NATNil

Throws:

InterpreterException
