Description copied from interface: Transformer

Perform the transformation defined by this on the given input object and return the resulting object

Specified by:

transform in interface Transformer

Parameters:

returnClass - the class of the object that should be returned by this method. If not null, returned object must be an instance of this class, ie returnObject instanceof returnClass must be true. May be null, in which case the converter is not constrained in the class of the object it returns. Implementations may impose more restrictive semantics on this parameter.

objectToTransform - the object that should be transformed. If the original property to which the transormation is being applied was primitive-valued, then this will be the java.lang equivalent of the primitive value.

args - the arguments for transformation. these come from the {model,snapshot}-converter-arg-{1-9} attributes. For each arg, if the value is null, then no arg at that index was specified. It is up to to implementations to impose more precise semantics on this parameter.

context - the TransformContext for the overall transformation in progress

Returns:

the transformed value. If returnClass was specified, this must be an instance of that class, unless it represents a primitive type, in which case the returned value should be as follows, for possible values of returnClass:

short, int, long, byte, float, double

an instance of java.lang.Number

char

an instance of java.lang.Character

boolean

an instance of java.lang.Boolean
