Inheritance diagram for IPacketReader: Collaboration diagram for IPacketReader:A signal reader reads packets from a signal data stream.
Public Member Functions | |
| virtual ErrCode INTERFACE_FUNC | read (IPacket **packet)=0 |
| Retrieves the next available packet in the data-stream. More... | |
| virtual ErrCode INTERFACE_FUNC | readAll (IList **packets)=0 |
| Retrieves all the currently available packets in the data-stream. More... | |
| Public Member Functions inherited from IReader | |
| virtual ErrCode INTERFACE_FUNC | getAvailableCount (SizeT *count)=0 |
| Gets the number of segments available to read. More... | |
| virtual ErrCode INTERFACE_FUNC | setOnDataAvailable (IProcedure *callback)=0 |
Sets the specified callback function to be called when there is available data in the reader. Pass nullptr to unset the callback. The callback should take no arguments. More... | |
| virtual ErrCode INTERFACE_FUNC | getEmpty (Bool *empty)=0 |
| Checks if there is data to read. More... | |
| Public Member Functions inherited from IBaseObject | |
| virtual ErrCode INTERFACE_FUNC | borrowInterface (const IntfID &intfID, void **obj) const =0 |
| Returns another interface which is supported by the object without incrementing the reference count. More... | |
| virtual ErrCode INTERFACE_FUNC | dispose ()=0 |
| Disposes all references held by the object. More... | |
| virtual ErrCode INTERFACE_FUNC | getHashCode (SizeT *hashCode)=0 |
| Returns hash code of the object. More... | |
| virtual ErrCode INTERFACE_FUNC | equals (IBaseObject *other, Bool *equal) const =0 |
| Compares object to another object for equality. More... | |
| virtual ErrCode INTERFACE_FUNC | toString (CharPtr *str)=0 |
| Returns a string representation of the object. More... | |
| Public Member Functions inherited from IUnknown | |
| virtual ErrCode INTERFACE_FUNC | queryInterface (const IntfID &intfID, void **obj)=0 |
| Returns another interface which is supported by the object and increments the reference count. More... | |
| virtual int INTERFACE_FUNC | addRef ()=0 |
| Increments the reference count for an interface on an object. More... | |
| virtual int INTERFACE_FUNC | releaseRef ()=0 |
| Decrements the reference count for an interface on an object. More... | |
Retrieves the next available packet in the data-stream.
| [out] | packet | The next available packet or nullptr if not are available. |
