Method Detail

getInverse

public ILcdObjectTransformation getInverse()

Description copied from interface: ILcdObjectTransformation

Returns the inverse transformation. getInverse().transform( transform( object ) ) should always return an object that can be considered equal to the given object. When the transformation has no inverse, null should be returned.

Specified by:

getInverse in interface ILcdObjectTransformation

Returns:

the inverse transformation

transform

public abstract Object transform(Object aObject,
                                 Map<Object,Object> aContext)

Description copied from interface: ILcdObjectTransformation

Transforms the given value to another value. The given aObject should not be null. The context can be used to share information between transformations.

Specified by:

transform in interface ILcdObjectTransformation

Parameters:

aObject - the value to transform

aContext - the context

Returns:

the transformed value

invert

protected abstract Object invert(Object aObject,
                                 Map<Object,Object> aContext)

Returns the inverse of the given object.

Parameters:

aObject - the object on which the inverse transformation should be performed

aContext - the transformation context

Returns:

the inverted object
