All Superinterfaces:

Cloneable, MetaDataObject, ResourceSpecifier, Serializable, XMLizable

All Known Subinterfaces:

public interface ResourceCreationSpecifier
extends ResourceSpecifier

A ResourceCreationSpecifier is the supertype of AnalysisEngineDescription, CasConsumerDescription, CollectionReaderDescription, and CasInitializerDescription.

All Resource Creation Specifiers must the following:

• frameworkImplementation: The name of the UIMA framework in which the component executes. The name for this implementation is given by Constants.JAVA_FRAMEWORK_NAME. A component that runs in the C++ enablement layer needs to have the framework name given by Constants.CPP_FRAMEWORK_NAME.
• implementationName: The fully-qualified Java class name of the user's component (Annotator, CAS Consumer, Collection Reader, or CAS Initializer).
• metaData: the ResourceMetaData describing the resource

The following are optional:

• A set of ExternalResourceDependency objects that define this resource's dependencies on other resources.
• A set of ExternalResourceDescription objects that satisfy the dependencies.

Method Detail

getFrameworkImplementation

String getFrameworkImplementation()

Gets the name of the AE framework implementation within which the Resource executes. The framework name for this implementation is given by Constants.JAVA_FRAMEWORK_NAME..

Returns:

the framework implementation name

setFrameworkImplementation

void setFrameworkImplementation(String aFrameworkImplementation)

Sets the name of the AE framework implementation within which the ResourceCreationSpecifier executes. The framework name for this implementation is given by Constants.JAVA_FRAMEWORK_NAME..

Parameters:

aFrameworkImplementation - the framework implementation name

getImplementationName

String getImplementationName()

Retrieves the name of this ResourceCreationSpecifier's implementation. This must be a fully qualified Java class name.

Returns:

the implementation name of the CasConsumer

setImplementationName

void setImplementationName(String aImplementationName)

Sets the name of this ResourceCreationSpecifier's implementation. This must be a fully qualified Java class name.

Parameters:

aImplementationName - the implementation name of the CasConsumer

getMetaData

ResourceMetaData getMetaData()

Retrieves the ResourceMetaData to assign to the newly constructed ResourceCreationSpecifier.

Returns:

the metadata for the new resource. This will always be modifiable.

setMetaData

void setMetaData(ResourceMetaData aMetaData)

Sets the MetaData for this ResourceCreationSpecifier.

Parameters:

aMetaData - metadata to assign

getExternalResourceDependencies

ExternalResourceDependency[] getExternalResourceDependencies()

Retrieves descriptions of this ResourceCreationSpecifier's dependencies on external resources. Each required external resource is assigned a String identifier. This is the identifier that this ResourceCreationSpecifier can use to locate the Resource (using the AnnotatorContext.getResourceObject(String) method).

Returns:

an array of ExternalResourceDependency objects that describe this AnalysisEngine's resource dependencies.

setExternalResourceDependencies

void setExternalResourceDependencies(ExternalResourceDependency[] aDependencies)

Sets the descriptions of this ResourceCreationSpecifier's dependencies on external resources.

Parameters:

aDependencies - an array of ExternalResourceDependency objects that describe this ResourceCreationSpecifier's resource dependencies.

getExternalResourceDependency

ExternalResourceDependency getExternalResourceDependency(String aKey)

Gets the external resource dependency with the given key.

Parameters:

aKey - the key of the external resource dependency to get

Returns:

the resource dependency with the specified key, null if none.

getResourceManagerConfiguration

ResourceManagerConfiguration getResourceManagerConfiguration()

Retrieves the Resource Manager configuration, which declares the resources that satisfy the dependencies defined by getExternalResourceDependencies().

Returns:

the Resource Manager configuration that describes how external resource dependencies are bound to actual resources.

setResourceManagerConfiguration

void setResourceManagerConfiguration(ResourceManagerConfiguration aResourceManagerConfiguration)

Sets the Resource Manager configuration, which declares the resources that satisfy the dependencies defined by getExternalResourceDependencies().

Parameters:

aResourceManagerConfiguration - the Resource Manager configuration that describes how external resource dependencies are bound to actual resources.

validate

void validate()
              throws ResourceInitializationException,
                     ResourceConfigurationException

Checks that this ResourceCreationSpecifier is valid. An exception is thrown if it is not valid. This only does fairly lightweight checking. To do a more complete but more expensive check, use doFullValidation().

Throws:

ResourceInitializationException - if aDesc is invalid

ResourceConfigurationException - if the configuration parameter settings in aDesc are invalid

validate

void validate(ResourceManager aResourceManager)
              throws ResourceInitializationException,
                     ResourceConfigurationException

Checks that this ResourceCreationSpecifier is valid. An exception is thrown if it is not valid. This only does fairly lightweight checking. To do a more complete but more expensive check, use doFullValidation().

Parameters:

aResourceManager - a ResourceManager instance to use to resolve imports by name.

Throws:

ResourceInitializationException - if aDesc is invalid

ResourceConfigurationException - if the configuration parameter settings in aDesc are invalid

doFullValidation

void doFullValidation()
                      throws ResourceInitializationException

Does full validation of this ResourceCreationSpecifier. This essentially performs all operations necessary to instantiate a Resource except that it does not actually instantiate the implementation class. If appropriate, this method will also attempt to create a CAS based on the descriptor, in order to do full type system verification. If any operations fail, an exception will be thrown.

Throws:

ResourceInitializationException - if validation failed

doFullValidation

void doFullValidation(ResourceManager aResourceManager)
                      throws ResourceInitializationException

Does full validation of this ResourceCreationSpecifier. This essentially performs all operations necessary to instantiate a Resource except that it does not actually instantiate the implementation class. If appropriate, this method will also attempt to create a CAS based on the descriptor, in order to do full type system verification. If any operations fail, an exception will be thrown.

Parameters:

aResourceManager - a ResourceManager instance to use to load annotator classes, external resource classes, and resolve imports by name.

Throws:

ResourceInitializationException - if validation failed
