folly::DefaultKeepAliveExecutor

Name

Description

Executor

Schedules and runs asynchronous work.

Name

Description

WeakRefExecutor

Marker base for the weak‐reference executor wrappers.

Name

Description

KeepAlive

Alias for ExecutorKeepAlive, a safe pointer to an Executor.

Name

Description

~DefaultKeepAliveExecutor [destructor] [virtual]

Destroys the executor, asserting its keep‐alive has already been joined.

add [virtual]

Enqueue a function to be executed by this executor. This and all variants must be threadsafe.

addWithPriority [virtual]

Enqueue a function with a given priority, where 0 is the medium priority This is up to the implementation to enforce

getNumPriorities [virtual]

Returns the number of priority levels this executor supports.

weakRef

Returns a weak keep‐alive to this executor.

Name

Description

getKeepAliveToken

getKeepAliveToken overloads

getWeakRef

Returns a weak keep‐alive to executor that does not extend its lifetime.

invokeCatchingExns

Invokes f, logging and swallowing any exception it throws.

Name

Description

HI_PRI

Highest schedulable priority.

LO_PRI

Lowest schedulable priority.

MID_PRI

Medium (default) schedulable priority.

Name

Description

joinAndResetKeepAlive

Joins the keep‐alive, then reinstates a fresh one so the executor is reusable.

joinKeepAlive

Releases this executor's own keep‐alive and waits for all others to drain.

keepAliveAcquire [virtual]

Acquire a keep alive token. Should return false if keep‐alive mechanism is not supported.

keepAliveRelease [virtual]

Release a keep alive token previously acquired by keepAliveAcquire(). Will never be called if keepAliveAcquire() returns false.

Name

Description

isKeepAliveDummy

Returns true if the KeepAlive is constructed from an executor that does not support the keep alive ref‐counting functionality

keepAliveAcquire

Acquires a keep‐alive reference on executor.

keepAliveRelease

Releases a keep‐alive reference on executor.

makeKeepAlive

Makes a counted (non‐dummy, non‐alias) keep‐alive referring to executor.

Name

Description

async_tracing::logFutureVia

Trace hook invoked when a Future is rescheduled onto an executor.

async_tracing::logGetGlobalCPUExecutor

Trace hook invoked when the global CPU executor is retrieved.

async_tracing::logGetImmutableCPUExecutor

Trace hook invoked when the immutable CPU executor is retrieved.

async_tracing::logSemiFutureVia

Trace hook invoked when a SemiFuture is rescheduled onto an executor.

async_tracing::logSetGlobalCPUExecutor

Trace hook invoked when the global CPU executor is set.

Name

Description

ThreadPoolExecutor

Base class for implementing threadpool based executors.

VirtualExecutor

VirtualExecutor implements a light‐weight view onto existing Executor.
