Idle

discards packets

SYNOPSIS§

Idle

Batching: Batching natively supported
Ports: any number of inputs, any number of outputs
Processing: agnostic

DESCRIPTION§

Idle never pushes a packet to any output or pulls a packet from any input. Any packet it does receive by push is discarded. Idle is often used to avoid "input not connected" error messages.

Idle provides an upstream-empty notifier to inform downstream pullers that it is dormant. As a result, in the configuration

 Idle -> SimpleQueue -> Discard;

the Discard element will itself go dormant. Use SimpleIdle to avoid this effect.
