Subject RE: Bean Field Serialization/Deserialization
Date Mon, 22 Apr 2002 12:51:57 GMT
I don't understand why you don't intend to use BeanInfo instead of creating
your own class descriptor (TypeDesc).
I know that PropertyDescriptor doesn't contain all the informations
required, but is it impossible to could extend it, or to use it by default,
or something like that ...

Objet : Bean Field Serialization/Deserialization

There has been some discussion and bugs related to the serialization and
deserialization of
beans that do not have getter/setters but instead have public fields.

I am working on the following change.

Changes to utils.BeanPropertyDescriptor:
*  Add constructor to set BPD with a java.lang.reflect.Field.  So now a BPD
be constructed for a Field or it can be constructed with a read/write
Method pair.
* Get rid of the getReadMethod/getWriteMethod methods.
* Instead have set/get methods which will use the methods if available or
use the field.
* Have isReadable, isWriteable, isIndexed methods to query the BPD.

Changes to utils.BeanUtils
* Add the BPD's for public fields that do not have getters/setters.

Changes to encoding/ser/BeanPropertyTarget
* Change the getWriteMethod calls to use the new BPD.set calls...simplifies
this code.

Changes to encoding/ser/BeanSerializer & BeanDeserializer
* Similar changes to remove getWriteMethod and getReadMethod calls and use
the set/get and other query methods.  This also simplifies the code.

Any comments ?
