Method Detail

lookupRTDataFeeder

public RTDataFeeder lookupRTDataFeeder(java.lang.String name)
                                throws PanamaException

Get a run-time DataFeeder by name. This method is similar in concept to ModelServices.lookupDataFeeder. However, while ModelServices always returns Panama model objects, this method can return an instance of a user-specified class that implements the RTDataFeeder interface.

Parameters:

name - the name of the RTDataFeeder to look up

Returns:

RTDataFeeder for the given name

Throws:

PanamaException - if the named RTDataFeeder could not be found

lookupRTDataFeeder

public RTDataFeeder lookupRTDataFeeder(long id)
                                throws PanamaException

Get a run-time DataFeeder by id. This method is similar in concept to ModelServices.lookupDataFeeder. However, while ModelServices always returns Panama model objects, this method can return an instance of a user-specified class that implements the RTDataFeeder interface.

Parameters:

id - the id of the RTDataFeeder to look up: this should be the id returned by registerRTDataFeeder

Returns:

RTDataFeeder for the given name

Throws:

PanamaException - if the named RTDataFeeder could not be found

registerRTDataFeeder

public long registerRTDataFeeder(java.lang.String name,
RTDataFeeder rtdf)
                          throws PanamaException

Register a RTDataFeeder (pass-through DataFeeder).

Returns:

unique id of the newly registred RTDataFeeder

PanamaException
