Creates a new transformation provider.

Method Detail

getObjectTransformation

public ILcdObjectTransformation getObjectTransformation(TLcdDataType aSourceType,
                                                        TLcdDataType aTargetType)

Returns the object transformation that can transform instances of the given source type to instances of the given target type. Returns null if no such transformation can be found.

The implementation first looks for transformation that have been registered on this instance for the given source and target type. If no such transformation can be found, it tries to find an appropriate default transformation.

Parameters:

aSourceType - the source type

aTargetType - the target type

Returns:

an object transformation that transforms from source type to target type

getTargetTypes

public Collection<TLcdDataType> getTargetTypes(TLcdDataType aType)

Returns a collection of target data types for which transformations have been registered for the given source type.

Parameters:

aType - the source type

Returns:

the collection of target types for which a transformation has been registered for the given source type

register

public void register(TLcdDataType aSourceType,
                     TLcdDataType aTargetType,
                     ILcdObjectTransformation aTransformation)

Registers a transformation from the given source type to the given target type. If the transformation has an inverse, the inverse will be available on this object's inverse (see getInverse().

Parameters:

aSourceType - the source type

aTargetType - the target type

aTransformation - the transformation to register

getInverse

public TLcdObjectTransformationProvider getInverse()

Returns the inverse of this provider. Typically, each transformation that is registered on this instance and that has an inverse, will be available on the returned inverse.

Returns:

the inverse of this provider
