          Description

Interface Summary
ClientSocketFactory Interface ClientSocketFactory is used to create non-default client sockets.
DistributedMember This is the fundamental representation of a member in a GemFire distributed system.
Role Members of the distributed system can fill one or more user defined roles.
 

Class Summary
AbstractLauncher<T extends Comparable<T>> The AbstractLauncher class is a base class for implement various launchers to construct and run different GemFire processes, like Cache servers or Locators, Managers, HTTP servers and so on.
AbstractLauncher.ServiceState<T extends Comparable<T>> The ServiceState is an immutable type representing the state of the specified Locator at any given moment in time.
DistributedLockService A named instance of DistributedLockService defines a space for locking arbitrary names across the distributed system defined by a specified distribution manager.
DistributedSystem A "connection" to a GemFire distributed system.
DurableClientAttributes Class DurableClientAttributes represents durable member attributes.
Locator Represents a distribution locator server that provides discovery information to members and clients of a GemFire distributed system.
LocatorLauncher The LocatorLauncher class is a launcher for a GemFire Locator.
LocatorLauncher.Builder Following the Builder design pattern, the LocatorLauncher Builder is used to configure and create a properly initialized instance of the LocatorLauncher class for running the Locator and performing other Locator operations.
LocatorLauncher.LocatorState The LocatorState is an immutable type representing the state of the specified Locator at any given moment in time.
ServerLauncher The ServerLauncher class is a launcher class with main method to start a GemFire Server (implying a GemFire Cache server process).
ServerLauncher.Builder The Builder class, modeled after the Builder creational design pattern, is used to construct a properly configured and initialized instance of the ServerLauncher to control and run GemFire servers (in particular, cache servers).
ServerLauncher.ServerState The ServerState is an immutable type representing the state of the specified Locator at any given moment in time.
 

Enum Summary
AbstractLauncher.Status The Status enumerated type represents the various lifecycle states of a GemFire service (such as a Cache Server, a Locator or a Manager).
LocatorLauncher.Command An enumerated type representing valid commands to the Locator launcher.
ServerLauncher.Command An enumerated type representing valid commands to the Server launcher.
 

Exception Summary
DistributedSystemDisconnectedException Thrown when a GemFire distributed system has been terminated.
FutureCancelledException Thrown when a Future has been cancelled.
GatewayCancelledException Thrown when a GemFire oplog has been terminated.
LeaseExpiredException A LeaseExpiredException is thrown when GemFire detects that a distributed lock obtained by the current thread with a limited lease (see @link DistributedLockService} has expired before it was explicitly released.
LockNotHeldException A LockNotHeldException is thrown when attempting unlock a lock that is not held by the thread performing the unlock.
LockServiceDestroyedException A LockServiceDestroyedException is thrown when attempting use a distributed lock service that has been destroyed.
OplogCancelledException Thrown when a GemFire gateway has been terminated.
PoolCancelledException Thrown when a GemFire pool has been cancelled.
TXManagerCancelledException Thrown when a GemFire transaction manager has been terminated.
 

Package com.gemstone.gemfire.distributed Description

Provides information about, access to, and common tools for GemFire distributed systems. When a program wishes to access distributed dtaa data stored in GemFire, it first creates a DistributedSystem that will connect to the distributed system. GemFire provides two means of discovering the other members in a distributed group. The first uses IP multicast to broadcast a message to all members that listen on a given port and address. The second method of discovery uses special VMs called "locators" to keep track of the members of the distributed system. Each locator is identified by a host/port pair that is specified when connecting to the distributed system.
