Class CompositeResourceFactory_impl

java.lang.Object
  org.apache.uima.impl.CompositeResourceFactory_impl

All Implemented Interfaces:

CompositeResourceFactory, ResourceFactory

public class CompositeResourceFactory_impl
extends java.lang.Object
implements CompositeResourceFactory

A registry containing (ResourceSpecifier Class, ResourceFactory) pairs. Also implements the ResourceFactory interface, and produces resources by delegating to the most recently registered ResourceFactory instance that can handle the class of the given specifier object.

Method Summary

Resource	produceResource(java.lang.Class<? extends Resource> aResourceClass, ResourceSpecifier aSpecifier, java.util.Map<java.lang.String,java.lang.Object> aAdditionalParams) Produces an appropriate Resource instance from a ResourceSpecifier.

Method Detail

produceResource

public Resource produceResource(java.lang.Class<? extends Resource> aResourceClass,
                                ResourceSpecifier aSpecifier,
                                java.util.Map<java.lang.String,java.lang.Object> aAdditionalParams)
                         throws ResourceInitializationException

Description copied from interface: ResourceFactory

Produces an appropriate Resource instance from a ResourceSpecifier. This version of produceResource takes a Map containing additional parameters to be passed to the Resource.initialize(ResourceSpecifier,Map) method.

Specified by:

produceResource in interface ResourceFactory

Parameters:

aResourceClass - the class of resource to be produced (NOTE: this is intended to be a standard UIMA interface name such as "TextAnalysisEngine" or "ASB")

aSpecifier - an object that specifies how to acquire an instance of a Resource.

aAdditionalParams - a Map containing additional parameters to pass to the Resource.initialize(ResourceSpecifier,Map) method. May be null if there are no parameters.

Returns:

a Resource instance. Returns null if this factory does not know how to create a Resource from the ResourceSpecifier provided.

Throws:

ResourceInitializationException - if a failure occurred during production of the resource

registerFactory

public void registerFactory(java.lang.Class aResourceSpecifierInterface,
                            ResourceFactory aFactory)

Description copied from interface: CompositeResourceFactory

Registers a ResourceFactory with this composite factory.

Specified by:

registerFactory in interface CompositeResourceFactory

Parameters:

aResourceSpecifierInterface - the subinterface of ResourceSpecifier that the factory can handle

aFactory - the factory used to create resources from resource specifiers of the given type
