Field Detail

key

protected ProtocolKey key

The idenity of this service, note that it may not be active yet.

---

topModule

protected ModuleInstance topModule

The top module instance

---

protocolTable

protected java.util.Hashtable protocolTable

List of protocols.

---

moduleInstances

protected java.util.Vector moduleInstances

---

monitor

protected BaseMonitor monitor

---

inShutdown

protected boolean inShutdown

---

serviceType

protected org.apache.derby.iapi.services.monitor.PersistentService serviceType

The type of service this was created by. If null then this is a non-persistent service.

---

serviceLocale

java.util.Locale serviceLocale

Constructor Detail

TopService

TopService(BaseMonitor monitor)

---

TopService

TopService(BaseMonitor monitor,
           ProtocolKey key,
           org.apache.derby.iapi.services.monitor.PersistentService serviceType,
           java.util.Locale serviceLocale)

Method Detail

setTopModule

protected void setTopModule(java.lang.Object instance)

---

getService

protected java.lang.Object getService()

---

isPotentialService

protected boolean isPotentialService(ProtocolKey otherKey)

---

isActiveService

boolean isActiveService()

---

isActiveService

boolean isActiveService(ProtocolKey otherKey)

---

findModule

protected java.lang.Object findModule(ProtocolKey key,
                                      boolean findOnly,
                                      java.util.Properties properties)

Find an module in the protocol table that supports the required protocol name combination and can handle the properties. Returns the instance of the module or null if one does not exist in the protocol table.

---

bootModule

java.lang.Object bootModule(boolean create,
                            java.lang.Object service,
                            ProtocolKey key,
                            java.util.Properties properties)
                      throws org.apache.derby.iapi.error.StandardException

Boot a module, performs three steps.

1. Look for an existing module in the protocol table
2. Look for a module in the implementation table that handles this protocol
3. Create an instance that handles this protocol.

---

shutdown

boolean shutdown()

If the service is already beign shutdown we return false.

---

addToProtocol

private boolean addToProtocol(ProtocolKey key,
                              ModuleInstance module)

Add a running module into the protocol hash table. Return true if the module was added successfully, false if it couldn't be added. In the latter case the module should be shutdown if its reference count is 0.

---

inService

protected boolean inService(java.lang.Object instance)

---

getKey

public ProtocolKey getKey()

---

getServiceType

org.apache.derby.iapi.services.monitor.PersistentService getServiceType()

---

stop

private static void stop(java.lang.Object instance)

---
