Class DateFormatSupplier

java.lang.Object

java.lang.ThreadLocal<DateFormat>

org.apache.accumulo.core.util.format.DateFormatSupplier

All Implemented Interfaces:

Supplier<DateFormat>

public abstract class DateFormatSupplier
extends ThreadLocal<DateFormat>
implements Supplier<DateFormat>

DateFormatSupplier is a ThreadLocal<DateFormat> that will set the correct TimeZone when the object is retrieved by get(). This exists as a way to get around thread safety issues in DateFormat. This class also contains helper methods that create some useful DateFormatSuppliers. Instances of DateFormatSuppliers can be shared, but note that a DateFormat generated from it will be shared by all classes within a Thread. In general, the state of a retrieved DateFormat should not be changed, unless it makes sense to only perform a state change within that Thread.
