Interface RuntimeModel

All Known Implementing Classes:

PropertyRuntime, PropertyRuntimeModel, RuntimeModel

public interface RuntimeModel

This RuntimeModel is used by the XL run-time system as an interface to the access of properties. It corresponds to a compile-time model which was used at compile-time: The invocation of CompiletimeModel.getRuntimeName() returns a name, which is passed to RuntimeModelFactory.modelForName(java.lang.String, java.lang.ClassLoader) in order to obtain the corresponding RuntimeModel.

A comprehensive specification of the behaviour of RuntimeModel is given by the specification of the XL programming language.

Nested Class Summary

static interface

RuntimeModel.Property

Method Summary

void	initialize(java.lang.String params) Initializes this model.
RuntimeModel.Property	propertyForName(java.lang.String name, java.lang.ClassLoader loader)
RuntimeModel.Property	propertyForName(java.lang.String name, TypeLoader loader) Returns the run-time Property for a given name.

Method Detail

initialize

void initialize(java.lang.String params)

Initializes this model. This method is invoked by RuntimeModelFactory.modelForName(java.lang.String, java.lang.ClassLoader) after a new Model instance has been created. The format of params depends on implementations of Model.

Parameters:

params - initialization parameters, possibly null

propertyForName

RuntimeModel.Property propertyForName(java.lang.String name,
                                      java.lang.ClassLoader loader)

propertyForName

RuntimeModel.Property propertyForName(java.lang.String name,
                                      TypeLoader loader)

Returns the run-time Property for a given name. The name has to be a name which was returned by an invocation of CompiletimeModel.Property.getRuntimeName() for a compile-time property at compile-time. The implementation has to return the corresponding run-time property. If classes have to be loaded, the loader has to be used.

Parameters:

name - the name of the property, as returned by the compile-time property

loader - a loader for loading of classes

Returns:

the run-time property corresponding to name
