Instance methods

AcquireLock

Makes multiple attempts to acquire a lock by its key within a given time interval.

public AcquireLock(IContext context, string key, long ttl, long timeout)

  • 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.
  • timeout: long - lock acquisition timeout.

ReleaseLock

Releases a prevously acquired lock by its key.

public 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 - a lock timeout (time to live) in milliseconds.
