copyvoid copy(Object from, Object to, Map<String, Object> context, Collection<String> exclusions, Collection<String> inclusions) Copies the properties in the object "from" and sets them in the object "to" using specified type converter, orXWorkConverterif none is specified.- Parameters:
- from- the source object
- to- the target object
- context- the action context we're running under
- exclusions- collection of method names to excluded from copying ( can be null)
- inclusions- collection of method names to included copying (can be null) note if exclusions AND inclusions are supplied and not null nothing will get copied.
 
- 
copyvoid copy(Object from, Object to, Map<String, Object> context, Collection<String> exclusions, Collection<String> inclusions, Class<?> editable) Copies the properties in the object "from" and sets them in the object "to" only setting properties defined in the given "editable" class (or interface) using specified type converter, orXWorkConverterif none is specified.- Parameters:
- from- the source object
- to- the target object

getRealTargetObject getRealTarget(String property, Map<String, Object> context, Object root) throws ReflectionExceptionLooks for the real target with the specified property given a root Object which may be a CompoundRoot.- Parameters:
- property- specified property
- context- the context
- root- the root object
- Returns:
- the real target or null if no object can be found with the specified property

- 
getBeanMapCreates a Map with read properties for the given source object.If the source object does not have a read property (i.e. write-only) then the property is added to the map with the value here is no read method for property-name.- Parameters:
