Method Detail

initialize

public boolean initialize(ResourceSpecifier aSpecifier,
                          java.util.Map<java.lang.String,java.lang.Object> aAdditionalParams)
                   throws ResourceInitializationException

Called by the framework to initialize this Collection Reader. Subclasses should generally NOT override this method; instead they should override the zero-argument initialize() method and access metadata via the getProcessingResourceMetaData() method. This method is non-final only for legacy reasons.

Specified by:

initialize in interface Resource

Overrides:

initialize in class Resource_ImplBase

Parameters:

aSpecifier - specifies how to create a resource or locate an existing resource service.

aAdditionalParams - a Map containing additional parameters. May be null if there are no parameters. Each class that implements this interface can decide what additional parameters it supports.

Returns:

true if and only if initialization completed successfully. Returns false if the given ResourceSpecifier is not of an appropriate type for this Resource. If the ResourceSpecifier is of an appropriate type but is invalid or if some other failure occurs, an exception should be thrown.

Throws:

ResourceInitializationException - if a failure occurs during initialization.

See Also:

Resource.initialize(org.apache.uima.resource.ResourceSpecifier, java.util.Map)

initialize

public void initialize()
                throws ResourceInitializationException

This method is called during initialization, and does nothing by default. Subclasses should override it to perform one-time startup logic.

Throws:

ResourceInitializationException - if a failure occurs during initialization.

destroy

public void destroy()

Description copied from interface: Resource

Releases all resources held by this Resource.

Specified by:

destroy in interface Resource

Overrides:

destroy in class Resource_ImplBase

See Also:

Resource.destroy()

getProcessingResourceMetaData

public ProcessingResourceMetaData getProcessingResourceMetaData()

Description copied from interface: BaseCollectionReader

Gets the metadata that describes this CasProcesor.

Specified by:

getProcessingResourceMetaData in interface BaseCollectionReader

Returns:

an object containing all metadata for this CasProcessor

See Also:

BaseCollectionReader.getProcessingResourceMetaData()

isConsuming

public boolean isConsuming()

Description copied from interface: BaseCollectionReader

Gets whether this is a consuming CollectionReader. Consuming CollectionReaders remove each element from the Collection as it is read.

Specified by:

isConsuming in interface BaseCollectionReader

Returns:

true if and only if this is a consuming CollectionReader

See Also:

BaseCollectionReader.isConsuming()
