Detailed Description
This class describes a generic control capability, as used in H.239
Constructor & Destructor Documentation
| H323GenericControlCapability::H323GenericControlCapability | ( | const PString & | identifier | ) |
Create a new data capability.
- Parameters:
-
identifier Indentifer (OID) for generic control

| const H245_H2250LogicalChannelParameters * | param | |||
| ) | const [virtual] |
Create the channel instance, allocating resources as required. This creates a logical channel object appropriate for the parameters provided. Not if param is NULL, sessionID must be provided, otherwise this is taken from the fields in param.
- Parameters:
-
connection Owner connection for channel dir Direction of channel sessionID Session ID for RTP channel param Parameters for channel
Implements H323Capability.
| virtual MainTypes H323GenericControlCapability::GetMainType | ( | ) | const [virtual] |
Get the main type of the capability. Always returns e_Data.
Implements H323Capability.
| virtual unsigned H323GenericControlCapability::GetSubType | ( | ) | const [virtual] |
Get the sub-type of the capability. This is a code dependent on the main type of the capability.
This returns H245_VideoCapability::e_extendedVideoCapability.
Implements H323Capability.
| virtual PBoolean H323GenericControlCapability::IsMatch | ( | const PASN_Choice & | subTypePDU | ) | const [virtual] |
Compare the generic part of the capability, if applicable.
- Parameters:
-
subTypePDU sub-type PDU of H323Capability
Reimplemented from H323Capability.
| virtual PBoolean H323GenericControlCapability::OnReceivedPDU | ( | const H245_Capability & | pdu | ) | [virtual] |
This function is called whenever and incoming TerminalCapabilitySet PDU is received on the control channel, and a new H323Capability descendent was created. This completes reading fields from the PDU into the classes members.
If the function returns PFalse then the received PDU codec description is not supported, so will be ignored. The default behaviour simply returns PTrue.
- Parameters:
-
pdu PDU to get information from
Reimplemented from H323Capability.
| virtual PBoolean H323GenericControlCapability::OnSendingPDU | ( | H245_ModeElement & | pdu | ) | const [virtual] |
This function is called whenever and outgoing RequestMode PDU is being constructed for the control channel. It allows the capability to set the PDU fields from information in members specific to the class.
The default behaviour is pure.
- Parameters:
-
pdu PDU to set information on
Implements H323Capability.
| virtual PBoolean H323GenericControlCapability::OnSendingPDU | ( | H245_Capability & | pdu | ) | const [virtual] |
This function is called whenever and outgoing TerminalCapabilitySet PDU is being constructed for the control channel. It allows the capability to set the PDU fields from information in members specific to the class.
The default behaviour calls the OnSendingPDU() function with a more specific PDU type.
- Parameters:
-
pdu PDU to set information on
Implements H323Capability.
