Class BeanMorpher

java.lang.Object

net.sf.ezmorph.bean.BeanMorpher

All Implemented Interfaces:

Morpher, ObjectMorpher

public final class BeanMorpher
extends java.lang.Object
implements ObjectMorpher

Converts a JavaBean into another JavaBean or DynaBean.
This Morpher will try to match every property from the target JavaBean's class to the properties of the source JavaBean. If any target property differs in type from the source property, it will try to morph it. If a Morpher is not found for that type, the conversion will be aborted with a MorphException; this may be changed by setting the Morpher to be lenient, in that way it will ignore the property (the resulting value will be null).

Specified by:

morph in interface ObjectMorpher

Parameters:

sourceBean - The input value to be morphed

morphsTo

public java.lang.Class morphsTo()

Description copied from interface: Morpher

Returns the target Class for conversion.

Specified by:

morphsTo in interface Morpher

Returns:

the target Class for conversion.

supports
