Constructor Details

LockExecutorImpl

private LockExecutorImpl(AutoLock lock)

Creates an instance of LockExecutorImpl.

Parameters:

lock - The lock.

Method Details

evaluate

public boolean evaluate(Constraint constraint)
                 throws AutoLock.ExecutionFailedException

Evaluates the given condition.

Specified by:

evaluate in interface LockExecutor

Parameters:

constraint - The constraint.

Returns:

The result of the evaluation of the condition.

Throws:

AutoLock.ExecutionFailedException - The evaluation failed for some reason.

execute

public <T> Optional<T> execute(Operation<T> operation)
                        throws AutoLock.ExecutionFailedException

Executes the given operation.

Specified by:

execute in interface LockExecutor

Type Parameters:

T - The type of the operation's result.

Parameters:

operation - The operation.

Returns:

An instance of Optional that holds the result of the operation.

Throws:

AutoLock.ExecutionFailedException - The operation failed for some reason.

of

public static final LockExecutor of(Lock lock)

Creates a new LockExecutor from the given Lock instance.

Parameters:

lock - The lock.

Returns:

The new LockExecutor.

of

public static final LockExecutor of(AutoLock lock)

Creates a new LockExecutor from the given AutoLock instance.

Parameters:

lock - The lock.

Returns:

The new LockExecutor.

perform

public void perform(Action action)
             throws AutoLock.ExecutionFailedException

Performs the given action after obtaining the lock.

This differs from LockExecutor.execute(Operation) as Action does not return something, and a warning regarding "Result of assignment expression used" can be avoided in case the action is used to set an attribute.

Specified by:

perform in interface LockExecutor

Parameters:

action - The action.

Throws:

AutoLock.ExecutionFailedException - The action failed for some reason.
