Member Function Documentation

add()

virtual int zth::PollerServerBase::add ( Pollable &  p, Client *  client  )

pure virtualnoexcept

Add a Pollable, that belongs to a given client.

client can be nullptr.

Returns

0 on success, otherwise an errno

Implemented in zth::PollerServer< PollItem_ >, and zth::PollerServer< zmq_pollitem_t >.

migrateTo()

virtual int zth::PollerServerBase::migrateTo ( PollerServerBase &  p )

pure virtualnoexcept

Move all registered Pollables to another server.

Returns

0 on success, otherwise an errno

Implemented in zth::PollerServer< PollItem_ >, and zth::PollerServer< zmq_pollitem_t >.

poll()

virtual int zth::PollerServerBase::poll ( int  timeout_ms )

pure virtualnoexcept

Poll.

The Pollables with events are not saved in the server, but these are forwarded to the registered Client.

Returns

0 when a Pollable returned an event, otherwise an errno

Implemented in zth::PollerServer< PollItem_ >, and zth::PollerServer< zmq_pollitem_t >.

remove()

virtual int zth::PollerServerBase::remove ( Pollable &  p, Client *  client  )

pure virtualnoexcept

Remove the given Pollable, belonging to the given client.

client must match the one that was specified during add().

Returns

0 on success, otherwise an errno

Implemented in zth::PollerServer< PollItem_ >, and zth::PollerServer< zmq_pollitem_t >.
