Method Detail

getNodeDao

public NodeDao getNodeDao()

setNodeDao

public void setNodeDao(NodeDao nodeDao)

getIpInterfaceDao

public IpInterfaceDao getIpInterfaceDao()

setIpInterfaceDao

public void setIpInterfaceDao(IpInterfaceDao ipInterfaceDao)

dataSourceSync

@Transactional
public void dataSourceSync()

Clears and synchronizes the internal known IP address cache with the current information contained in the database. To synchronize the cache the method opens a new connection to the database, loads the address, and then closes it's connection.

Specified by:

dataSourceSync in interface InterfaceToNodeCache

Throws:

SQLException - Thrown if the connection cannot be created or a database error occurs.

getNodeId

public int getNodeId(String location,
                     InetAddress addr)

Returns the nodeid for the IP Address

Specified by:

getNodeId in interface InterfaceToNodeCache

Parameters:

addr - The IP Address to query.

Returns:

The node ID of the IP Address if known.

setNodeId

@Transactional
public int setNodeId(String location,
                                    InetAddress addr,
                                    int nodeid)

Sets the IP Address and Node ID in the Map.

Specified by:

setNodeId in interface InterfaceToNodeCache

Parameters:

addr - The IP Address to add.

nodeid - The Node ID to add.

Returns:

The nodeid if it existed in the map.

removeNodeId

public int removeNodeId(String location,
                        InetAddress addr)

Removes an address from the node ID map.

Specified by:

removeNodeId in interface InterfaceToNodeCache

Parameters:

addr - The address to remove from the node ID map.

Returns:

The nodeid that was in the map.

size

public int size()

Specified by:

size in interface InterfaceToNodeCache

clear

public void clear()
