ODP is a framework that lets you manage bidirectional conversion between instances of GVBuffer and generic objects, the access to the generic objects fields will be execute through OGNL and / or XPath. Each Data provider contains a field element identify by a key, this fileds are of three type:
- IN,
- OUT,
IN-OUT
All data provider field contains the elements that define a field identified by a key, these fields can be of three types in, out, in-out. The fields of type IN operation is performed on the input object type getValue going to put in execution context with the key defined, then in subsequent expressions we use these values by logging in with the syntax # key when OGNL expressions. The fields are defined type out only if you want to make the expression that modify object context.
