MemoryLock

Lock used to synchronize the execution of a process using shared memory.

Inherits: Lock

Description

The MemoryLock class is used to synchronize the execution of a process using shared memory.

Important points

This implementation is not suitable for synchronization of distributed processes.

Configuration parameters

options:

retry_timeout: timeout in milliseconds to retry lock acquisition. (Default: 100)

Instance methods

ReleaseLock

Releases a prevously acquired lock by its key.

public override void ReleaseLock(string correlationId, string key)

correlationId: string - (optional) transaction id used to trace execution through the call chain.
key: string - unique lock key to release.

TryAcquireLock

Makes a single attempt to acquire a lock by its key. It returns immediately a positive or negative result.

public bool TryAcquireLock(string correlationId, string key, long ttl)

correlationId: string - (optional) transaction id used to trace execution through the call chain.
key: string - unique lock key to acquire.
ttl: long - lock timeout (time to live) in milliseconds.
returns: bool - lock result

Examples

var lock = new MemoryLock();
lock.TryAcquireLock("123", "key1", 0);
try {
   // Processing...
}
finally  {
   lock.ReleaseLock("123", "key1");
   // Continue...
});
