NEWEXECUTOR operator

The NEWEXECUTOR operator is the creation of an action that allows the execution of other actions in a new thread pool.

Syntax

NEWEXECUTOR action THREADS threadExpr [syncType]

Description

The NEWEXECUTOR operator creates an action that creates a new thread pool and executes the defined action in such a way that any action created with the NEWTHREAD operator will be executed in one of the threads of the created pool.

Parameters

• action

  A context-dependent action operator that defines an action to be executed.

• threadExpr

  An expression which value determines the number of threads in the pool. Must return the value of the INTEGER class.

• syncType

  Synchronisation type. Specifies when the execution of NEWEXECUTOR action completes, allowing you to choose between synchronous and asynchronous approaches. Specified by one of the keywords:

  • WAIT - after all threads have completed execution. This value is used by default.
  • NOWAIT - immediately after all threads have been started.

Examples

testExecutor  {
    NEWEXECUTOR {
        FOR id(Sku s) DO {
            NEWTHREAD {
                NEWSESSION {
                    name(s) <- STRING[20](id(s)); // writing the code into the name in 10 threads
                    APPLY;
                }
            }
        }
    } THREADS 10;
}
