Member Functions

Name

Description

basic_system_executor

Default constructor.

context

Obtain the underlying execution context.

defer

Request the system executor to invoke the given function object.

dispatch

Request the system executor to invoke the given function object.

execute

Oneway execution function.

on_work_finished

Inform the executor that some work is no longer outstanding.

on_work_started

Inform the executor that it has some outstanding work to do.

post

query

Query the current value of the allocator property.

query

Query the current value of the mapping property.

Query the current value of the context property.

Query the current value of the blocking property.

Query the current value of the relationship property.

require

Obtain an executor with the blocking.possibly property.

Obtain an executor with the blocking.always property.

Obtain an executor with the blocking.never property.

Obtain an executor with the relationship.continuation property.

Name

Description

operator!=

Compare two executors for inequality.

operator==

Compare two executors for equality.

The system executor represents an execution context where functions are permitted to run on arbitrary threads. When the blocking.never property is established, the system executor will schedule the function to run on an unspecified system thread pool. When either blocking.possibly or blocking.always is established, the executor invokes the function immediately.
