Exceptions

ExceptionCondition
[!:IllegalArgumentException] if key is null
[!:CacheLoaderException] if CacheLoader throws an exception
[!:CacheServerException] If an exception is received from the Java cache server. Only for Native Client regions.
[!:NotConnectedException] if not connected to the GemFire system because the client cannot establish usable connections to any of the servers given to it. For pools configured with locators, if no locators are available, innerException of NotConnectedException is set to NoAvailableLocatorsException.
[!:MessageException] If the message received from server could not be handled. This will be the case when an unregistered typeId is received in the reply or reply is not well formed. More information can be found in the log.
System TimeoutException if the operation timed out
[!:RegionDestroyedException] if this region has been destroyed
Remarks

For local region instance - returns the value with the specified key from the local cache only. For distributed region instance - If the value is not present locally then it is requested from the java server. If even that is unsuccessful then a local CacheLoader will be invoked if there is one.

The value returned by get is not copied, so multi-threaded applications should not modify the value directly, but should use the update methods.

Updates the [!:CacheStatistics.LastAccessedTime][!:CacheStatistics.HitCount], [!:CacheStatistics.MissCount], and LastModifiedTime (if a new value is loaded) for this region and the entry.
