Detailed Description

Wrapper module to create and access single DBManager instance.

The DBModule module is a frontend for the database manager. Upon being added to the module manager (e.g. in its init() method), it creates a single DBManager instance with parameters retrieved from the configuration database. In particular, the following configuration symbols are supported:

• db_stream_id : Id number for the stream to be used for database communications.
• db_fundamental_period : Period in milliseconds for fundamental operations of the database. This rate indicates roughly the minimum time in milliseconds between periodic updates and the minimum rate at which immediate changes will be propagated (See DBManager and DBBase for details).
• db_update_period : Period of update for database entry callbacks. The units are in module manager ticks.
• db_prio : Priority for database related threads. Negative values are relative to the main loop priority, whereas positive values are absolute QNX priorities. Note that this is currently ignored in Linux.

Member Function Documentation

DBManager* DBModule::getManager (  void   )  [inline]

This method returns the single DBManager instance created upon initialization. It is recommended that this instance is used for all database operations in RHexLib. The creation of a second database manager will waste resources and may cause weird behavior.
