Protected Attributes | |
| unsigned | maxBitRate |
An application may create a descendent off this class and override functions as required for descibing a codec.
| H323DataCapability::H323DataCapability | ( | unsigned | maxBitRate = 0 |
) |
Create a new data capability.
| maxBitRate | Maximum bit rate for data in 100's b/s |
| H323DataCapability::H323DataCapability | ( | unsigned | maxBitRate = 0 |
) |
Create a new data capability.
| maxBitRate | Maximum bit rate for data in 100's b/s |
| virtual MainTypes H323DataCapability::GetMainType | ( | ) | const [virtual] |
Get the main type of the capability. Always returns e_Data.
Implements H323Capability.
| virtual unsigned H323DataCapability::GetDefaultSessionID | ( | ) | const [virtual] |
Get the default RTP session. This function gets the default RTP session ID for the capability type. For example audio capabilities return the value RTP_Session::DefaultAudioSessionID etc.
The default behaviour returns 3, indicating a data session.
Reimplemented from H323Capability.
| virtual BOOL H323DataCapability::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.
| pdu | PDU to set information on |
Implements H323Capability.
| virtual BOOL H323DataCapability::OnSendingPDU | ( | H245_DataType & | pdu | ) | const [virtual] |
This function is called whenever and outgoing OpenLogicalChannel 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.
| pdu | PDU to set information on |
Implements H323Capability.
| virtual BOOL H323DataCapability::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 calls the OnSendingPDU() function with a more specific PDU type.
| pdu | PDU to set information on |
Implements H323Capability.
| virtual BOOL H323DataCapability::OnSendingPDU | ( | H245_DataApplicationCapability & | pdu | ) | const [virtual] |
This function is called whenever and outgoing TerminalCapabilitySet or OpenLogicalChannel 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.
| pdu | PDU to set information on |
Reimplemented in H323_H224Capability, H323NonStandardDataCapability, H323_T120Capability, and H323_T38Capability.
| virtual BOOL H323DataCapability::OnSendingPDU | ( | H245_DataApplicationCapability & | pdu, | |
| CommandType | type | |||

| pdu | PDU to set information on |
| type | Type of PDU to send in |
| virtual BOOL H323DataCapability::OnSendingPDU | ( | H245_DataMode & | pdu | ) | const [pure 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 sets the PDUs tag according to the GetSubType() function (translated to different enum).
| pdu | PDU to set information on |
Implemented in H323_H224Capability, H323NonStandardDataCapability, H323_T120Capability, and H323_T38Capability.
| virtual BOOL H323DataCapability::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 FALSE then the received PDU codec description is not supported, so will be ignored. The default behaviour simply returns TRUE.
| pdu | PDU to get information from |
Reimplemented from H323Capability.
| virtual BOOL H323DataCapability::OnReceivedPDU | ( | const H245_DataType & | pdu, | |
| BOOL | receiver | |||
| ) | [virtual] |
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.
| pdu | PDU to get information from |
| receiver | Is receiver OLC |
Implements H323Capability.
| virtual BOOL H323DataCapability::OnReceivedPDU | ( | const H245_DataApplicationCapability & | pdu | ) | [virtual] |
This function is called whenever and incoming TerminalCapabilitySet or 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.
| pdu | PDU to set information on |
Reimplemented in H323_H224Capability, H323NonStandardDataCapability, H323_T120Capability, and H323_T38Capability.
