Register a ConnectedDescriptor for read events.
- Parameters
-
descriptor | the ConnectedDescriptor to register. The OnData() method will be called when there is data available for reading. Additionally, OnClose() will be called if the other end closes the connection. |
delete_on_close | controls whether the descriptor is deleted when it's closed. |
- Returns
- true if the descriptor was registered, false otherwise.
Implements ola::io::PollerInterface.
◆ AddWriteDescriptor()
◆ Poll()
Poll the Descriptors for events and execute any callbacks.
- Parameters
-
timeout_manager | the TimeoutManager to use for timer events. |
poll_interval | the maximum time to block for. |
- Returns
- false if any errors occurred, true if events were handled.
Implements ola::io::PollerInterface.
◆ RemoveReadDescriptor() [1/2]
Unregister a ReadFileDescriptor for read events.
- Parameters
-
- Returns
- true if unregistered successfully, false otherwise.
- Precondition
- descriptor->ReadFileDescriptor() is valid.
