java.lang.Object

com.boomi.connector.util.ExpiringValue<V>

Direct Known Subclasses:

SimpleExpiringValue

public abstract class ExpiringValue<V>
extends Object

Base class for tracking a value which needs to expire after a certain amount of time or inactivity. When the current value is no longer valid, get() will return null.

This class is not thread-safe. The expectation is that subtypes of this class will be used within a ConnectorCache instance which manages the thread-safety.
