|
Create the capability for User Input. The subType parameter is a value from the enum H245_UserInputCapability::Choices. |
|
|
|
Create a copy of the object. |
|
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.
Implements H323Capability. |
|
Get the name of the media data format this class represents. Implements H323Capability. |
|
Get the main type of the capability. This function is overridden by one of the three main sub-classes off which real capabilities would be descendend. Implements H323Capability. |
|
Get the sub-type of the capability. This is a code dependent on the main type of the capability. Implements H323Capability. |
|
Validate that the capability is usable given the connection. This checks agains the negotiated protocol version number and remote application to determine if this capability should be used in TCS or OLC pdus. The default behaviour will check for early versions and return FALSE for RFC2833 mode. Reimplemented from H323Capability. |
|
This function is called whenever and incoming OpenLogicalChannel PDU has been used to construct the control channel. It allows the capability to set from the PDU fields, information in members specific to the class. The default behaviour is pure.
Implements H323Capability. |
|
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 FALSE then the received PDU codec description is not supported, so will be ignored. The default behaviour simply returns TRUE.
Reimplemented from H323Capability. |
|
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 calls the OnSendingPDU() function with a more specific PDU type.
