Constructor Detail

AcnetNodeTables

public AcnetNodeTables()

Method Detail

getAcnetNodeTables

protected static void getAcnetNodeTables()

getInetAddress

public static InetAddress getInetAddress(short trunk,
                                         short node)

Get the IP address for a specific Acnet trunk and node. Note that null is returned if the trunk/node is not supported on UDP/IP.

Parameters:

trunk - the trunk number

node - the node number

Returns:

InetAddress object

doesBigMes

public static boolean doesBigMes(short trunk,
                                 short node)

Inquire as the the capability of a node to handle big messages (32K bytes).

Parameters:

trunk - the trunk number

node - the node number

Returns:

true if big messages allowed for this trunk/node

setDaqUpDown

public static boolean setDaqUpDown(short trunk,
                                   short node,
                                   boolean upFlag)

Set the operating status of a data acquisition consolidation server to either UP or DOWN.

Parameters:

trunk - the trunk number of the daq

node - the node number of the daq

upFlag - true = UP, false = DOWN

Returns:

true if the status successfully modified

getTrunkNode

public static short[] getTrunkNode(String name)

Get the Acnet trunk and node numbers corresponding to a name. Warning: this method does not provide automatic translation to an IP node. See AcnetWrite.getAcnetTrunkNode

Parameters:

name - the Acnet node name

Returns:

trunk + node as array: trunk first (-1,-1 if error)

getAltTrunkNode

public static short[] getAltTrunkNode(String name)

Get the alternate Acnet trunk and node numbers corresponding to a name.

Parameters:

name - the Acnet node name

Returns:

trunk + node as array: trunk first (-1,-1 if error)

getAltTrunkNode

public static short[] getAltTrunkNode(short trunk,
                                      short node)

Get the alternate Acnet trunk and node numbers corresponding to a trunk and node.

Parameters:

trunk - the trunk number

node - the node number

Returns:

trunk + node as array: trunk first (-1,-1 if error)

getAcnetName

public static String getAcnetName(short trunk,
                                  short node)

Get the Acnet node name corresponding to a trunk and node.

Parameters:

trunk - the trunk number

node - the node number

Returns:

node name, or null

getIpName

public static String getIpName(String name)

Get the IP node name corresponding to an Acnet name

Parameters:

name - the Acnet node name

Returns:

IP node name, or null

getDaqTrunkNode

public static short[] getDaqTrunkNode(short trunk,
                                      short node)

Get the trunk and node number of the data acquisition consolidator node associated with the input trunk and node. If the primary daq consolidator is down, the next available daq consolidator will be returned. Special values returned include (-1,-1) if input node not defined, and (0,0) if no available (and UP) daq server could be found. If the input trunk/node has no assigned daq consolidator, the input trunk and node may be returned as output values.

Parameters:

trunk - the trunk number

node - the node number

Returns:

trunk + node as array: trunk first

getAcnetFromIPName

public static String getAcnetFromIPName(String name)

Get the Node object corresponding to an ip name

Parameters:

name - the ip name

Returns:

the Acnet node name (or null)

getLocalTrunkNode

public static short[] getLocalTrunkNode()

Get the LOCAL Acnet trunk and node number

Returns:

trunk + node as array: trunk first (-1,-1 if error)

getLocalTrunk

public static int getLocalTrunk()

Get the LOCAL Acnet trunk.

Returns:

the LOCAL ACNET trunk (-1 if error)

getLocalNode

public static int getLocalNode()

Get the LOCAL Acnet node.

Returns:

the LOCAL ACNET node (-1 if error)

getLocalAcnetName

public static String getLocalAcnetName()

Get the LOCAL Acnet node name

Returns:

node name (String)
