org.joda.time.tz
Class CachedDateTimeZone

java.lang.Object
  org.joda.time.DateTimeZone
      org.joda.time.tz.CachedDateTimeZone

All Implemented Interfaces:: Serializable

public class CachedDateTimeZone
extends DateTimeZone
extends DateTimeZone

Improves the performance of requesting time zone offsets and name keys by caching the results. Time zones that have simple rules or are fixed should not be cached, as it is unlikely to improve performance.

CachedDateTimeZone is thread-safe and immutable.

Since:: 1.0

Method Summary
`boolean`	`equals(Object obj)` Compare this datetime zone with another.
`static CachedDateTimeZone`	`forZone(DateTimeZone zone)` Returns a new CachedDateTimeZone unless given zone is already cached.
`String`	`getNameKey(long instant)` Returns a non-localized name that is unique to this time zone.
`int`	`getOffset(long instant)` Gets the millisecond offset to add to UTC to get local time.
`int`	`getStandardOffset(long instant)` Gets the standard millisecond offset to add to UTC to get local time, when standard time is in effect.
`DateTimeZone`	`getUncachedZone()` Returns the DateTimeZone being wrapped.
`int`	`hashCode()` Gets a hash code compatable with equals.
`boolean`	`isFixed()` Returns true if this time zone has no transitions.
`long`	`nextTransition(long instant)` Advances the given instant to where the time zone offset or name changes.
