Member Function Documentation

add() [1/2]

virtual int zth::PollerInterface::add ( Pollable &  p )

pure virtualnoexcept

Add a pollable object.

Once a pollable is added, do not modify its properties, except for user_data.

Returns

0 on success, otherwise an errno

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

add() [2/2]

int zth::PollerInterface::add ( std::initializer_list< std::reference_wrapper< Pollable > >  l )

noexcept

Add pollable objects.

Returns

0 on success, otherwise an errno

Definition at line 22 of file poller.cpp.

empty()

virtual bool zth::PollerInterface::empty ( ) const

pure virtualnoexcept

Checks if there is any pollable registered.

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

remove()

virtual int zth::PollerInterface::remove ( Pollable &  p )

pure virtualnoexcept

Remove a pollable object.

Returns

0 on success, otherwise an errno

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

reserve()

virtual void zth::PollerInterface::reserve ( size_t  more )

pure virtual

Reserve memory to add more pollables.

Exceptions

std::bad_alloc

when allocation fails

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