Be familiar with the class and method for the Configuration
and Management components. The method retrieves information from the
context.
The ConfigContext class is used to establish a read-only configuration
context in which the configuration is guaranteed not to change for
as long as the context is maintained. This is useful for clients that
need to ensure that all the code executing under the same transaction
will have a consistent view of the configuration, independent of changes
to the configuration external to the transaction.
Note: The context
only applies within the same process (JVM) in which it was created.
For transactions that execute across many processes, the client
is responsible for ensuring a consistent view of the configuration,
possibly by passing those configuration values through all the method
calls in the transaction.
The public Node getConfigItemsMap() method retrieves the map of
the configuration corresponding to the context.
