Method Detail

initialize

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

Description copied from interface: Resource

Initializes this Resource from a ResourceSpecifier. Applications do not need to call this method. It is called automatically by the ResourceFactory and cannot be called a second time.

Specified by:

initialize in interface Resource

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. Reutrns 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.

destroy

public void destroy()

Description copied from interface: Resource

Releases all resources held by this Resource.

Specified by:

destroy in interface Resource

Resource.destroy()

getMetaData

public ResourceMetaData getMetaData()

Description copied from interface: Resource

Gets the metadata that describes this Resource.

Specified by:

getMetaData in interface Resource

Returns:

an object containing all metadata for this resource.

See Also:

Resource.getMetaData()

setMetaData

protected void setMetaData(ResourceMetaData aMetaData)

Sets the ResourceMetaData object associated with this Resource. Any previously existing metadata will be replaced.

Resource subclasses should call this method during initialization in order to set the metadata before any calls to getMetaData() are made.

Parameters:

aMetaData - metadata to assign to this Resource

getLogger

public Logger getLogger()

Description copied from interface: Resource

Gets the Logger that this Resource is currently using.

Specified by:

getLogger in interface Resource

Returns:

this Resource's logger

See Also:

setLogger

public void setLogger(Logger aLogger)

Description copied from interface: Resource

Sets the Logger that this Resource will use. If this method is not called, the default logger (UIMAFramework.getLogger()) will be used.

Specified by:

setLogger in interface Resource

Parameters:

aLogger - the logger for this Resource to use

See Also:

Resource.setLogger(org.apache.uima.util.Logger)

getResourceManager

public ResourceManager getResourceManager()

Description copied from interface: Resource

Gets the ResourceManager that this Resource uses to locate other Resources.

Specified by:

getResourceManager in interface Resource

Returns:

the ResourceManager

See Also:

getUimaContext

public UimaContext getUimaContext()

Description copied from interface: Resource

Gets the UIMA Context for this Resource. This can be used to access external resources or facilities such as the Logger.

Specified by:

public UimaContextAdmin getUimaContextAdmin()

Gets the Admin interface to this Resource's UimaContext.

Specified by:

getUimaContextAdmin in interface Resource

Returns:

the administrative interface to this Resource's UimaContext

getCasManager

public CasManager getCasManager()
