folly::Executor

Name

Description

KeepAlive

Alias for ExecutorKeepAlive, a safe pointer to an Executor.

Name

Description

~Executor [destructor] [virtual]

Destroys the executor.

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.

Name

Description

getKeepAliveToken

getKeepAliveToken overloads

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

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
