Functionality

This class provides a buffer for table keys. Its purpose is to hold new primary keys that are not yet persisted in the according database table.

This is specifically the case in create function modules that use CALL ... IN UPDATE TASK for persistingnew entries (with new primary keys). Since such new entries don't exist in the database until COMMITWORK is called, it is next to impossible to check their primary keys in subsequent function calls within the same transaction.

This is where this class comes in. Whenever a new entry is created, that is the update function is queued,its primary key is set in this buffer class. Within the next call to the update function, this buffer is queried for the primary key of the to be created entry.
