is a one-instance service that provides access to a set of
Contents via ContentProviders.
If the instance is created with two arguments of type string,
these two strings are used to configure the newly instantiated broker;
see the description of the required
::com::sun::star::lang::XInitialization interface for
details.
If the instance is created without arguments, the newly instatiated
broker is not configured.
must be implemented to make it possible to resolve cyclic object
references.
Those references i.e. may occure if content provider implementations
hold references to the Broker. The Broker itself always holds its
providers. If the Broker shall be released,
::com::sun::star::lang::XComponent::dispose
must be called at the Broker. The implementation of this method must
call
::com::sun::star::lang::XEventListener::disposing
on the registered listeners (the providers holding the Broker must be
those listeners) and release the appropriate object references. At
the other hand, the implementation of XEventListener::disposing must
release its appropriate references.
supports the configuration of a newly created broker.
The
::com::sun::star::lang::XInitialization::initialize
method should be called with two arguments of type string. These strings
are used as a pair of keys to retrieve a set of content provider
descriptions from the configuration management (stored at
org.openoffice.ucb.Configuration.ContentProviders.key1.SecondaryKeys.key2.ProviderData
within the configuration management's hierarchy). The retrieved
descriptions are in turn used to register the corresponding content
provider services at the broker.
Typical values for the pair of strings would be
"Local"/"Office", to configure a broker that
contains all the relevant content providers.
enables the caller to execute commands at the broker.
This interface is required.
