[OJB-developers] OJB enhancements to 07.343

[Jakob B. <jbr...@ho...>]

hi,

the attached zip contains several enhancements to version 07.343:

- deferred loading (lazy) for 1:1 relationships
- wasNull when reading from ResultSet
- platform cacheing
- platform functions for setObject(), setNull()
- a MySql platform to fix setObject for Types.BIT
- StatementManager bindInsert and bindUpdate use platform functions now

the most important feature is deferred loading for 1:1 relationships. it's
based on DynamicProxies and thus requires you to implement an interface for
the target side of the relationship (referenced.class). to enable it, use
<proxyReference>true</proxyReference> in ReferenceDescriptor:

<ReferenceDescriptor id="1">
    <rdfield.name>partner</rdfield.name>
    <referenced.class>brj.ojb.Person</referenced.class>
    <fk_descriptor_ids>9</fk_descriptor_ids>
    <proxyReference>true</proxyReference>
</ReferenceDescriptor>

for consistency i also renamed <proxy> to <proxyCollection> for
CollectionDescriptor.
