public class NATException

extends NATByCopy

Instances of the class NATException provide a AmbientTalk representation for the default instances of all InterpreterExceptions. They allow catching exceptions thrown by the interpreter in AmbientTalk, as well as raising them for within custom code.

asNativeException

public NATException asNativeException()
                               throws XTypeMismatch

Specified by:

asNativeException in interface ATConversions

Overrides:

asNativeException in class NATNil

Throws:

XTypeMismatch

getWrappedException

public InterpreterException getWrappedException()

meta_newInstance

public ATObject meta_newInstance(ATTable initargs)
                          throws InterpreterException

Description copied from interface: ATObject

Create a new instance of the receiver object. AmbientTalk mimics the initialization protocol of Class-based languages like Smalltalk. In a typical CBL, object initialization equals class allocation + new instance initialization. In AmbientTalk, class allocation is replaced by cloning via the meta_clone operation. Object initialization itself differs from cloning in that it additionally initializes the clone. For standard AmbientTalk objects, this happens by invoking a method named 'init' on the newly created instance.

Specified by:

meta_newInstance in interface ATObject

Overrides:

meta_newInstance in class NATNil

Throws:

InterpreterException

meta_isRelatedTo

public ATBoolean meta_isRelatedTo(ATObject object)
                           throws InterpreterException

Description copied from interface: ATObject

Detects whether both objects have a common origin, in other words whether they are related through a combination of the cloning and extension operators.

Specified by:

meta_isRelatedTo in interface ATObject

Overrides:

meta_isRelatedTo in class NATNil

Throws:

InterpreterException

meta_getStripes

public ATTable meta_getStripes()
                        throws InterpreterException

Description copied from class: NATNil

By default, a native object (and also nil) has no stripes.

Specified by:

meta_getStripes in interface ATObject

Overrides:

meta_getStripes in class NATNil

Throws:

InterpreterException
