  • Method Details

    • getChanges

      public org.eclipse.milo.opcua.stack.core.types.structured.ModelChangeStructureDataType[] getChanges() throws org.eclipse.milo.opcua.stack.core.UaException
      Description copied from interface: GeneralModelChangeEventType
      Get the local value of the Changes Node.

      The returned value is the last seen; it is not read live from the server.

      Specified by:
      getChanges in interface GeneralModelChangeEventType
      Returns:
      the local value of the Changes Node.
      Throws:
      org.eclipse.milo.opcua.stack.core.UaException - if an error occurs creating or getting the Changes Node.
    • setChanges

      public void setChanges(org.eclipse.milo.opcua.stack.core.types.structured.ModelChangeStructureDataType[] value) throws org.eclipse.milo.opcua.stack.core.UaException
      Description copied from interface: GeneralModelChangeEventType
      Set the local value of the Changes Node.

      The value is only updated locally; it is not written to the server.

      Specified by:
      setChanges in interface GeneralModelChangeEventType
      Parameters:
      value - the local value to set for the Changes Node.
      Throws:
      org.eclipse.milo.opcua.stack.core.UaException - if an error occurs creating or getting the Changes Node.
    • readChanges

      public org.eclipse.milo.opcua.stack.core.types.structured.ModelChangeStructureDataType[] readChanges() throws org.eclipse.milo.opcua.stack.core.UaException
      Description copied from interface: GeneralModelChangeEventType
      Read the value of the Changes Node from the server and update the local value if the operation succeeds.
      Specified by:
      readChanges in interface GeneralModelChangeEventType
      Returns:
      the ModelChangeStructureDataType value read from the server.
      Throws:
      org.eclipse.milo.opcua.stack.core.UaException - if a service- or operation-level error occurs.
    • writeChanges

      public void writeChanges(org.eclipse.milo.opcua.stack.core.types.structured.ModelChangeStructureDataType[] value) throws org.eclipse.milo.opcua.stack.core.UaException
      Description copied from interface: GeneralModelChangeEventType
      Write a new value for the Changes Node to the server and update the local value if the operation succeeds.
      Specified by:
      writeChanges in interface GeneralModelChangeEventType
      Parameters:
      value - the ModelChangeStructureDataType value to write to the server.
      Throws:
      org.eclipse.milo.opcua.stack.core.UaException - if a service- or operation-level error occurs.
    • readChangesAsync

      public CompletableFuture<? extends org.eclipse.milo.opcua.stack.core.types.structured.ModelChangeStructureDataType[]> readChangesAsync()
      Description copied from interface: GeneralModelChangeEventType
      An asynchronous implementation of GeneralModelChangeEventType.readChanges().
      Specified by:
      readChangesAsync in interface GeneralModelChangeEventType
      Returns:
      a CompletableFuture that completes successfully with the value or completes exceptionally if an operation- or service-level error occurs.
    • writeChangesAsync

      public CompletableFuture<org.eclipse.milo.opcua.stack.core.types.builtin.StatusCode> writeChangesAsync(org.eclipse.milo.opcua.stack.core.types.structured.ModelChangeStructureDataType[] changes)
      Description copied from interface: GeneralModelChangeEventType
      Specified by:
      writeChangesAsync in interface GeneralModelChangeEventType
      Returns:
      a CompletableFuture that completes successfully with the operation result or completes exceptionally if a service-level error occurs.
    • getChangesNode

      public PropertyTypeNode getChangesNode() throws org.eclipse.milo.opcua.stack.core.UaException
      Description copied from interface: GeneralModelChangeEventType
      Get the Changes PropertyType Node, or null if it does not exist.

      The Node is created when first accessed and cached for subsequent calls.

      Specified by:
      getChangesNode in interface GeneralModelChangeEventType
      Returns:
      the Changes PropertyType Node, or null if it does not exist.
      Throws:
      org.eclipse.milo.opcua.stack.core.UaException - if an error occurs creating or getting the Node.
    • getChangesNodeAsync

      public CompletableFuture<? extends PropertyTypeNode> getChangesNodeAsync()
      Description copied from interface: GeneralModelChangeEventType
      Asynchronous implementation of GeneralModelChangeEventType.getChangesNode().
      Specified by:
      getChangesNodeAsync in interface GeneralModelChangeEventType
      Returns:
      a CompletableFuture that completes successfully with the PropertyType Node or completes exceptionally if an error occurs creating or getting the Node.
