getPropertyMapFromObject

public java.util.Map getPropertyMapFromObject(java.lang.Object example,
                                              boolean readRequired,
                                              boolean writeRequired)
                                       throws MarshallException
Description copied from interface: NamedConverter
Get a map of property names to implementations of Property.

HibernateBeanConverter (and maybe others) may want to provide alternate versions of bean.getClass(), and we may wish to fake or hide properties in some cases.

This implementation is preferred above the alternate: NamedConverter.getPropertyMapFromClass(Class, boolean, boolean) because it potentially retains important extra type information.

Specified by:
getPropertyMapFromObject in interface NamedConverter
Parameters:
example - The object to find bean info from
readRequired - The properties returned must be readable
writeRequired - The properties returned must be writeable
Returns:
An array of PropertyDescriptors describing the beans properties
Throws:
MarshallException - If the introspection fails
See Also:
NamedConverter.getPropertyMapFromClass(Class, boolean, boolean)

getPropertyMapFromClass

public java.util.Map getPropertyMapFromClass(java.lang.Class type,
                                             boolean readRequired,
                                             boolean writeRequired)
                                      throws MarshallException
Description copied from interface: NamedConverter
Get a map of property names to implementations of Property.

HibernateBeanConverter (and maybe others) may want to provide alternate versions of bean.getClass(), and we may wish to fake or hide properties in some cases.

If you have a real object to investigate then it is probably better to call NamedConverter.getPropertyMapFromObject(Object, boolean, boolean) because that version can take into accound extra runtime type info.

Specified by:
getPropertyMapFromClass in interface NamedConverter
Parameters:
type - The class to find bean info from
readRequired - The properties returned must be readable
writeRequired - The properties returned must be writeable
Returns:
An array of PropertyDescriptors describing the beans properties
Throws:
MarshallException - If the introspection fails
See Also:
NamedConverter.getPropertyMapFromObject(Object, boolean, boolean)
