The ManageApp uses MANAGEMENT-… messages to communicate with other applications to fetch summary and drilldown information regarding the application’s current configuration and resources, as well as requesting updates to those values where supported.
The Application base class performs callbacks to methods which applications must override in order to implement support for their configuration and resources. Applications will interact with those methods, and do not need to interact directly with these MANAGEMENT-… messages.
The MANAGEMENT-… messages are:
Note that these messages begin with the special
! character, and so are treated
as administration messages. They will be passed between applications using the
dedicated administration message FIFO mechanism, and will always be processed before
user-level messages are processed.
