  - isTolerateFaultyServerState
```
public boolean isTolerateFaultyServerState()

    Returns:
    
    true if faulty server states are tolerated
    
    See Also:
    
    setTolerateFaultyServerState(boolean)
  - setTolerateFaultyServerState
```
public void setTolerateFaultyServerState(boolean value)
```
    Sets whether the client tolerates a server that reports a state other than "Running".
    A server can be reachable and still report that it is not working, for example "Suspended" or "Failed". By default (false) the client treats that as a lost connection: isConnected() turns false and the connection listeners are told. The session itself is kept, not rebuilt, and its subscriptions stay in place; data the server sends for them in the meantime is still delivered. As soon as the server reports "Running" again the client counts as connected again. With true the client stays connected whatever state the server reports.
    
    The state "Unknown" never counts as a loss. The setting takes effect on a running session with the next keep-alive.
    
    Warning: Server data may be incorrect while the server is not "Running". Use true at your own risk.
    
    Parameters:
    
    value - true to tolerate faulty server states

```
    Gets endpoints on the opc ua server, filtered to match the transport protocol of the discovery URL. For example, if the discovery URL uses opc.tcp, only opc.tcp endpoints are returned - opc.https endpoints are excluded. This mirrors the behaviour of the C# SDK's GetEndpoints(Uri) method.
    Use discoverAllEndpoints(URI) if you need all endpoints regardless of transport protocol.
    
    Parameters:
    
    discoveryEndpointUri - the discovery URI (e.g. opc.tcp://localhost:48410)
    
    Returns:
    
    an array of EndpointDescription objects matching the transport protocol of the discovery URL

```
    Gets all endpoints on the opc ua server, regardless of transport protocol. Returns both opc.tcp and opc.https endpoints (and any other transports the server offers). This mirrors the behaviour of the C# SDK's GetAllEndpoints(Uri) method.

    �Too large� in this context means that the server is not able to return a larger response or that the number of results to return exceeds the maximum number of results to return that was specified by the client in the original Browse request.
    
    Parameters:
    
    releaseContinuationPoints - if true, passed continuationPoints shall be reset to free resources in the server. If false, passed continuationPoints shall be used to get the next set of browse information.
    
    continuationPoints - a list of server-defined opaque values that represent continuation points.
    
    Returns:
    
    a BrowseNextResponse object
    
    Throws:
    
    com.plccom.opc.ua.common.ServiceFaultException - on error while executing the operation

  - getComplexTypeSystem
```
public UaComplexTypeSystem getComplexTypeSystem()
```
    Creates a new UaComplexTypeSystem for this client session.
    Call load() on the returned instance to browse the server's DataType hierarchy and cache all StructureDefinition objects. After loading, use decode(ExtensionObject) to decode complex type values into UaStructuredValue instances.
    
    Example:
    
    UaComplexTypeSystem typeSystem = client.getComplexTypeSystem(); typeSystem.load(); UaStructuredValue value = typeSystem.decode(extensionObject); System.out.println(value.getField("Temperature"));
    Returns:
    
    a new UaComplexTypeSystem bound to this session
  - startReverseConnectListener
```
public void startReverseConnectListener(String listenUrl)
                                 throws Exception
```
    Configures the URL on which this client listens for incoming Reverse Connect connections from the server. The stack opens the ServerSocket internally. Call this before connectReverse(int).
    
    Parameters:
    
    listenUrl - the URL to listen on, e.g. "opc.tcp://localhost:48500"
    
    Throws:
    
    Exception - if the URL is invalid
  - stopReverseConnectListener
```
public void stopReverseConnectListener()
```
    Resets the reverse connect listener configuration.
  - connectReverse
```
public void connectReverse(int timeoutMs)
                    throws Exception
```
    Waits for an incoming ReverseHello from the server and establishes a session. Call startReverseConnectListener(String) first. Spec-compliant per OPC UA Part 6 Â§7.1.3: the session runs over the same TCP connection initiated by the server. The stack handles the ReverseHello -> Hello -> Acknowledge handshake on the accepted socket.
    
    Parameters:
    
    timeoutMs - timeout in milliseconds to wait for the server. Default: 60000.
    
    Throws:
    
    IllegalStateException - if the listener has not been started
    
    Exception - on connection or session errors
  - connectReverse
```
public void connectReverse()
                    throws Exception
```
    Waits for an incoming ReverseHello with default timeout of 60 seconds.
    
    Throws:
    
    Exception - if the connection fails or times out
  - disconnect
```
public void disconnect()
                throws com.plccom.opc.ua.common.ServiceFaultException,
                       com.plccom.opc.ua.common.ServiceResultException
```
    Deprecated.
    Use close() instead
    
    disconnect the Ua OpcUaClient from OPC Ua server
    
    Throws:
    
    com.plccom.opc.ua.common.ServiceFaultException - on error while executing the operation
    
    com.plccom.opc.ua.common.ServiceResultException - on communication error
  - addSessionConnectionStateChangeListener
```
public boolean addSessionConnectionStateChangeListener(SessionConnectionStateChangeListener handler)
```
    append a SessionConnectionStateChangeListener object to event register
    
    Parameters:
    
    handler - a SessionConnectionStateChangeListener object
    
    Returns:
    
    true (as specified by Collection#add)

```
public boolean removeSessionConnectionStateChangeListener(SessionConnectionStateChangeListener handler)
```
    remove a SessionConnectionStateChangeListener object from event register
    
    Parameters:
    
    handler - a SessionConnectionStateChangeListener element to be removed from this list, if present
    
    Returns:
    
    true if this list contained the specified element
  - addSessionKeepAliveListener
```
public boolean addSessionKeepAliveListener(SessionKeepAliveListener handler)
```
    append a SessionKeepAliveListener object to event register
    
    Parameters:
    
    handler - a SessionKeepAliveListener object
    
    Returns:
    
    true (as specified by Collection#add)
  - removeSessionKeepAliveListener
```
public boolean removeSessionKeepAliveListener(SessionKeepAliveListener handler)
```
    remove a SessionKeepAliveListener object from event register
    
    Parameters:
    
    handler - a SessionKeepAliveListener element to be removed from this list, if present
    
    Returns:
    
    true if this list contained the specified element
  - onSessionKeepAlive
```
public void onSessionKeepAlive(com.plccom.opc.ua.core.ServerStatusDataType serverStatusDataType,
                               com.plccom.opc.ua.core.ServerState serverState)
```
