Method Detail

startBridgeServer

public static com.gemstone.gemfire.cache.server.CacheServer startBridgeServer(String bridgeConfig)

Creates and starts a bridge server in the current cache using the given bridge configuration.

See Also:

createBridgeServer(String), startBridgeServer(java.lang.String)

createBridgeServer

public static com.gemstone.gemfire.cache.server.CacheServer createBridgeServer(String bridgeConfig)

Creates a bridge server in the current cache. The bridge is configured using the BridgeDescription corresponding to the given bridge configuration from BridgePrms.names.

Upon initial creation, selects a random port and registers the BridgeHelper.Endpoint in the BridgeBlackboard map. Starts of the bridge server will always use this port.

Throws:

HydraRuntimeException - if an attempt is made to reconfigure an existing bridge server.

startBridgeServer

public static com.gemstone.gemfire.cache.server.CacheServer startBridgeServer()

Starts the existing bridge server in the current cache.

Lazily creates the gateway disk store specified by #diskStoreName, using DiskStoreHelper.createDiskStore(String).

Throws:

HydraRuntimeException - if the bridge has not been created.

getBridgeServer

public static com.gemstone.gemfire.cache.server.CacheServer getBridgeServer()

Returns the bridge server for the current cache, or null if no bridge server or cache exists.

stopBridgeServer

public static void stopBridgeServer()

Stops the bridge server in the current cache, if it exists.

bridgeServerToString

public static String bridgeServerToString(com.gemstone.gemfire.cache.server.CacheServer bridge)

Returns the given bridge server as a string.

getBridgeDescription

public static BridgeDescription getBridgeDescription(String bridgeConfig)

Returns the BridgeDescription with the given configuration name from BridgePrms.names.

getEndpoints

public static List<BridgeHelper.Endpoint> getEndpoints()

Returns all bridge server endpoints from the BridgeBlackboard map, a possibly empty list. This includes all servers that have ever started, regardless of their distributed system or current active status.

getEndpoints

public static List getEndpoints(String distributedSystemName)

Returns all bridge server endpoints) for the specified distributed system from the BridgeBlackboard map, a possibly empty list. This includes all servers that have ever started for the system, regardless of their current active status.

getEndpointsInGroup

public static List getEndpointsInGroup(String distributedSystemName,
                                       String group)

Returns all bridge server endpoints) for the specified distributed system in the given server group from the BridgeBlackboard map, a possibly empty list. This includes all servers that have ever started for the system, regardless of their current active status.

getRemoteEndpoints

public static List getRemoteEndpoints()

Returns all remote bridge server endpoints from the BridgeBlackboard map, a possibly empty list. This includes all servers that have ever started, except for the caller (if it is a server), regardless of their distributed system or current active status.

getRemoteEndpoints

public static List getRemoteEndpoints(String distributedSystem)

Returns all remote bridge server endpoints for the specified distributed system from the BridgeBlackboard map, a possibly empty list. This includes all servers that have ever started, except for the caller (if it is a server), regardless of their current active status.

getEndpoint

protected static BridgeHelper.Endpoint getEndpoint(String[] groups)

Gets the bridge server endpoint for this VM from the shared BridgeBlackboard map using the given server groups. Lazily selects a random port and registers the endpoint in the map.

getEndpoint

protected static BridgeHelper.Endpoint getEndpoint(int port,
                                                   String[] groups)

Gets the bridge server endpoint for this VM from the shared BridgeBlackboard map using the given port and server groups. Registers the endpoint in the map.
