protected AbstractTcpPlugin(String protocol,
                 int defaultPort,
                 int defaultTimeout,
                 int defaultRetry)

Method Detail

checkConnection

protected final boolean checkConnection(ConnectionConfig config)

Test to see if the passed host-port pair is the endpoint for an Citrix server. If there is an Citrix server at that destination then a value of true is returned from the method. Otherwise a false value is returned to the caller.

Parameters:

config - a ConnectionConfig object.

Returns:

True if server supports Citrix on the specified port, false otherwise

closeSocket

protected void closeSocket(Socket socket,
               ConnectionConfig config)

closeSocket

Parameters:

socket - a Socket object.

config - a ConnectionConfig object.

checkProtocol

protected abstract boolean checkProtocol(Socket socket,
                    ConnectionConfig config)
                                  throws Exception

checkProtocol

Parameters:

socket - a Socket object.

config - a ConnectionConfig object.

Returns:

a boolean.

Throws:

Exception - if any.

createConnectionConfig

protected ConnectionConfig createConnectionConfig(InetAddress address,
                                      int port)

createConnectionConfig

Parameters:

address - a InetAddress object.

port - a int.

Returns:

a ConnectionConfig object.

getConnectionConfigList

protected List<ConnectionConfig> getConnectionConfigList(Map<String,Object> qualifiers,
                                             InetAddress address)

getConnectionConfigList

Parameters:

qualifiers - a Map object.

address - a InetAddress object.

Returns:

a List object.

getKeyedInteger

protected final int getKeyedInteger(Map<String,Object> qualifiers,
                  String key,
                  int defaultVal)

getKeyedInteger

Parameters:

qualifiers - a Map object.

key - a String object.

defaultVal - a int.

Returns:

a int.

getKeyedIntegerArray

protected final int[] getKeyedIntegerArray(Map<String,Object> qualifiers,
                         String key,
                         int[] defaultVal)

getKeyedIntegerArray

Parameters:

qualifiers - a Map object.

key - a String object.

defaultVal - an array of int.

Returns:

an array of int.

getPluginName

public final String getPluginName()

getPluginName

Returns:

Returns the pluginName.

getProtocolName

public final String getProtocolName()

Returns the name of the protocol that this plugin checks on the target system for support.

Specified by:

getProtocolName in interface Plugin

Specified by:

getProtocolName in class AbstractPlugin

Returns:

The protocol name for this plugin.

isProtocolSupported

public final boolean isProtocolSupported(InetAddress address)

Returns true if the protocol defined by this plugin is supported. If the protocol is not supported then a false value is returned to the caller. Returns true if the protocol defined by this plugin is supported. If the protocol is not supported then a false value is returned to the caller. Returns true if the protocol defined by this plugin is supported. If the protocol is not supported then a false value is returned to the caller.

Specified by:

isProtocolSupported in interface Plugin

Specified by:

isProtocolSupported in class AbstractPlugin

Parameters:

address - The address to check for support.

Returns:

True if the protocol is supported by the address.

isProtocolSupported

public final boolean isProtocolSupported(InetAddress address,
                          Map<String,Object> qualifiers)

Returns true if the protocol defined by this plugin is supported. If the protocol is not supported then a false value is returned to the caller. The qualifier map passed to the method is used by the plugin to return additional information by key-name. These key-value pairs can be added to service events if needed. Returns true if the protocol defined by this plugin is supported. If the protocol is not supported then a false value is returned to the caller. The qualifier map passed to the method is used by the plugin to return additional information by key-name. These key-value pairs can be added to service events if needed. Returns true if the protocol defined by this plugin is supported. If the protocol is not supported then a false value is returned to the caller.
