Class ComponentLoader

java.lang.Object
  org.objectweb.fractal.adl.AbstractLoader
      org.objectweb.fractal.adl.components.ComponentLoader

All Implemented Interfaces:

ComponentLoaderAttributes, Loader, org.objectweb.fractal.api.control.AttributeController, org.objectweb.fractal.api.control.BindingController

Direct Known Subclasses:

ArgumentComponentLoader

public class ComponentLoader
extends AbstractLoader
implements ComponentLoaderAttributes

A Loader to check Component nodes in definitions. This loader checks sub component names, loads the definitions referenced by the component nodes (and the "extends" attribute), and merges all these definitions into a single one (by following inheritance rules).

Field Summary

protected static java.util.logging.Logger	logger
protected java.util.Map<java.lang.String,java.lang.String>	nameAttributes The names of the "name" attribute for each AST node type.
NodeMerger	nodeMergerItf The node merger component used to merge AST.
