Returns the default value for this Morpher.

hashCode

public int hashCode()

Overrides:

hashCode in class Object

morph

public Object morph(Object value)

Description copied from interface: ObjectMorpher

Morphs the input object into an output object of the supported type.

Parameters:

value - The input value to be morphed

morphsTo

public Class morphsTo()

Description copied from interface: Morpher

Returns the target Class for conversion.
