|
| | DeviceDescriptor (int fd) |
| | Create a new DeviceDescriptor.
|
| |
| DescriptorHandle | ReadDescriptor () const |
| | Returns the read descriptor for this socket.
|
| |
| DescriptorHandle | WriteDescriptor () const |
| | Returns the write descriptor for this socket.
|
| |
| bool | Close () |
| | Close this DeviceDescriptor.
|
| |
| virtual ssize_t | Send (const uint8_t *buffer, unsigned int size) |
| | Write a buffer to the descriptor.
|
| |
| virtual ssize_t | Send (IOQueue *data) |
| | Write data from an IOQueue to a descriptor.
|
| |
| virtual int | Receive (uint8_t *buffer, unsigned int size, unsigned int &data_read) |
| | Read data from this descriptor.
|
| |
| virtual bool | SetReadNonBlocking () |
| | Enable on non-blocking reads..
|
| |
| int | DataRemaining () const |
| | Find out how much data is left to read.
|
| |
|
bool | IsClosed () const |
| | Check if the descriptor is closed.

| |
| void | SetOnClose (OnCloseCallback *on_close) |
| | Set the callback to be run when the descriptor is closed.
|
| |
| OnCloseCallback * | TransferOnClose () |
| | Take ownership of the on_close callback.
|
| |
| void | SetOnData (ola::Callback0< void > *on_read) |
| | Set the callback to be run when data is available for reading.
|
| |
| void | SetOnWritable (ola::Callback0< void > *on_write) |
| | Set the callback to be run when the descriptor can be written to.
|
| |
| void | PerformRead () |
| | Called when there is data available on the descriptor.
|
| |
| void | PerformWrite () |
| | Called when the descriptor can be written to.
