Class SynchronizedGetCode
java.lang.Object

+--ahc.util.SynchronizedGetCode
- public abstract class SynchronizedGetCode
- extends java.lang.Object
This class and performs a blocking wait on a lock and then retrieves an object.
The get operation first waits until a precondition is met and it can acquire a monitor, or until a
timout is reached. The monitor is passed in to the constructor, and the precondition must be provided
by implementing an abstract method.
If the precondition is met and the lock acquired, the actuel result is retrieved by calling the abstract
hook "getUnsynchronized".
This implementation retrieves the result without passing any parameters to the getUnsynchronized method.
