Member Data Documentation

executionQueue

ExecutionCommandQueue& Execution::Context::executionQueue

LiveModification

retired

bool Execution::Context::retired = false

Set when this context's ContextData has been replaced. A replaced ContextData can outlive its replacement: the tick holds a strong reference and audio_engine::sync() does not wait for the audio thread when running() is false. Until it dies it stays subscribed to the cable signal and to every port it bound, over an execution_state whose devices may already be gone, so retired contexts must do nothing.

Declared last: ContextData initialises Context positionally. UI thread only.

time

Execution::time_function Execution::Context::time

Used to map the "high-level" durations in score to low-level durations

For instance, milliseconds to microseconds or milliseconds to samples
