)

abstract TryLock : 
        key : 'TKey * 
        time : int64 * 
        timeunit : TimeUnit * 
        leaseTime : int64 * 
        leaseTimeunit : TimeUnit -> bool

Parameters

key: Type: TKey

time: Type: SystemInt64
maximum time to wait for the lock.
timeunit: Type: Hazelcast.CoreTimeUnit
time unit of the time argument.
leaseTime: Type: SystemInt64
time to wait before releasing the lock.
leaseTimeunit: Type: Hazelcast.CoreTimeUnit

Remarks

Tries to acquire the lock for the specified key for the specified lease time.

After lease time, the lock will be released.

If the lock is not available, then the current thread becomes disabled for thread scheduling purposes and lies dormant until one of two things happens:

the lock is acquired by the current thread, or
the specified waiting time elapses.

Warning:

This method uses hashCode and equals of the binary form of the key, not the actual implementations of hashCode and equals defined in the key's class.
