/** Singleton class to manage retrieved input stream data in Writer
|
|
|
|
OD 2007-01-29 #i73788#
|
|
The instance of this class provides data container for retrieved input
|
|
stream data. The data container is accessed via a key, which the data
|
|
manager provides on creation of the data container.
|
|
When a certain data container is filled with data, an user event is submitted
|
|
to trigger the processing of with data.
