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(IContext context, string key)
- context: IContext - (optional) a context to trace execution through a 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(IContext context, string key, long ttl)
- context: IContext - (optional) a context to trace execution through a 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...
});
