 Question |
Tell me about component Buffer?
|
 Answer
|
When you open any page in a component, the system retrieves all of the data records for the entire component and stores them in one set of record buffers, organized by scroll level and then by page level. This component buffer consists of rows of buffer fields that hold data for the various records that are associated with page controls, including the primary records; related display records, derived work records, and translate table records.
PeopleCode frequently must refer to data in the Component Buffer, that is, the area in memory that stores data for the currently active component.
There are two methods of specifying a piece of data in the Component Buffer from within PeopleCode:
-------- Contextual references, which refer to data relative to the location of the currently executing PeopleCode program.
-------- References using scroll path syntax, which provide a complete, or absolute, path through the Component Buffer to the referenced component.
