Interface ExternalResourceDependency

All Superinterfaces:

Cloneable, MetaDataObject, Serializable, XMLizable

public interface ExternalResourceDependency
extends MetaDataObject

An ExternalResourceDependency object describes an resources's requirements on an external resource. This object has four properties:

• A key, by which the annotator will identify the resource.
• A textual description of the resource dependency.
• The name of a Java interface through which the data will be accessed. This is optional; if not specified, the default DataResource interface will be used.
• Whether the resource is required or optional.

Method Summary

String	getDescription() Retrieves the textual description of the resource.
String	getInterfaceName() Retrieves the name of the Java interface through which this resource will be accessed.
String	getKey() Retrieves the key by which the resource is identified.
boolean	isOptional() Gets whether this resource dependency is optional.
void	setDescription(String aDescription) Retrieves the textual description of the resource.
void	setInterfaceName(String aName) Sets the name of the Java interface through which this resource will be accessed.
void	setKey(String aKey) Sets the key by which the resource is identified.
void	setOptional(boolean aOptional) Sets whether this resource dependency is optional.

Method Detail

getKey

String getKey()

Retrieves the key by which the resource is identified.

Returns:

the key for this resource.

setKey

void setKey(String aKey)

Sets the key by which the resource is identified.

Parameters:

aKey - the key for this resource.

getDescription

String getDescription()

Retrieves the textual description of the resource.

Returns:

the textual description of the resource.

setDescription

void setDescription(String aDescription)

Retrieves the textual description of the resource.

Parameters:

aDescription - the textual description of the resource.

getInterfaceName

String getInterfaceName()

Retrieves the name of the Java interface through which this resource will be accessed.

Returns:

the name of the Java interface for this external resource, null if none.

setInterfaceName

void setInterfaceName(String aName)

Sets the name of the Java interface through which this resource will be accessed.

Parameters:

aName - the name of the Java interface for this external resource, null if none.

Throws:

UIMA_UnsupportedOperationException - if this object is not modifiable

isOptional

boolean isOptional()

Gets whether this resource dependency is optional. Dependencies that are not optional must be linked to resource definitions prior to instantiating the Analysis Engine, or an exception will be thrown.

Returns:

true if this resource dependency is optional, false if not

setOptional

void setOptional(boolean aOptional)

Sets whether this resource dependency is optional. Dependencies that are not optional must be linked to resource definitions prior to instantiating the Analysis Engine, or an exception will be thrown.

Parameters:

aOptional - true if this resource dependency is optional, false if not
