Interface MappingService

All Known Implementing Classes:

BidiMappingService, SpringBidiMappingService, SpringBidiMappingService

public interface MappingService

Interface for mapping a set of keysets into corresponding values.

The back end mapping implementation is not defined by this interface. Examples could be a simple Map or a remote terminology service, for which proper implementations of this interface must be provided.

Method Detail

get

Object get(Object mappingKey,
           Object key)

Parameters:

mappingKey - mapping name

key - left side of the mapping

Returns:

the value mapped by a registered mapping. The implementation of the mapping implements the behavior if the key does not exist.

Throws:

IllegalArgumentException - if the mappingKey is not registered.

get

Object get(Object mappingKey,
           Object key,
           Object defaultValue)

Parameters:

mappingKey - mapping name

key - left side of the mapping

defaultValue - default right side if there is no mapping for the code

Returns:

the value mapped by a registered mapping. If no mapping exists, the default value if returned. The implementation of the mapping implements the behavior if the key does not exist.

Throws:

IllegalArgumentException - if the mappingKey is not registered.

getKey

Object getKey(Object mappingKey,
              Object value)

Reverse mapping (Optional implementation)

Parameters:

mappingKey - mapping name

value - right side of the mapping

Returns:

the key mapped by a registered mapping. The implementation of the mapping implements the behavior if the value does not exist.

Throws:

IllegalArgumentException - if the mappingKey is not registered.

getKey

Object getKey(Object mappingKey,
              Object value,
              Object defaultKey)

Reverse mapping (Optional implementation)

Parameters:

mappingKey - mapping name

value - right side of the mapping

defaultKey - default left side

Returns:

the key mapped by a registered mapping. If no mapping exists, the default value if returned. The implementation of the mapping implements the behavior if the key does not exist.

Throws:

IllegalArgumentException - if the mappingKey is not registered.

getKeySystem

Object getKeySystem(Object mappingKey)

Parameters:

mappingKey - mapping name

Returns:

a formal identification of the key system (e.g. an OID)

Throws:

IllegalArgumentException - if the mappingKey is not registered.

getValueSystem

Object getValueSystem(Object mappingKey)

Parameters:

mappingKey - mapping name

Returns:

a formal identification of the value system (e.g. an OID)

Throws:

IllegalArgumentException - if the mappingKey is not registered.

mappingKeys

Set<?> mappingKeys()

Returns:

a set of names of all registered mappings. Changes to the set do not change the registry itself.

keys

Set<?> keys(Object mappingKey)

Parameters:

mappingKey - mapping key

Returns:

key set of a registered mapping. Changes to the set do not change the registry itself.

Throws:

IllegalArgumentException - if the mappingKey is not registered.

values

Collection<?> values(Object mappingKey)

Parameters:

mappingKey - mapping key

Returns:

value set of a registered mapping. Changes to the set do not change the registry itself.

Throws:

IllegalArgumentException - if the mappingKey is not registered.
