Constructor Detail

ReflectiveInstanceVariable

public ReflectiveInstanceVariable(NodeManagerUaNode nodeManager,
                                  NodeId nodeId,
                                  Object source,
                                  String propertyName,
                                  NodeId instanceDeclarationId)
                           throws SecurityException,
                                  NoSuchMethodException,
                                  StatusException

Create a new node, referring to an instance declaration node.

Parameters:

nodeManager - The node manager to which the node is created.

nodeId - The ID of the new node.

source - the node, whose property is wrapped using reflection

propertyName - the name of the wrapped property - parent must have a getPropertyName and optionally also a setPropertyName method. The propertyName is used as the BrowseName and DisplayName of the property node.

instanceDeclarationId - The ID of the instance declaration node, which this node is referring to. I.e. the same variable or property as this one, but under the type, instead of the instance.

Throws:

StatusException - if instanceDeclarationId cannot be converted to a variable node

NoSuchMethodException - if the getter for the defined property does not exist

SecurityException - if the getter for the defined property cannot be accessed

ReflectiveInstanceVariable

public ReflectiveInstanceVariable(NodeManagerUaNode nodeManager,
                                  NodeId nodeId,
                                  Object source,
                                  String propertyName,
                                  UaVariable instanceDeclaration)
                           throws NoSuchMethodException

Create a new node, referring to an instance declaration node.

Parameters:

nodeManager - The node manager to which the node is created.

nodeId - The ID of the new node.

source - the node, whose property is wrapped using reflection

propertyName - the name of the wrapped property - parent must have a getPropertyName and optionally also a setPropertyName method. The propertyName is used as the BrowseName and DisplayName of the property node.

instanceDeclaration - The instance declaration node, which this node is referring to. I.e. the same variable or property as this one, but under the type, instead of the instance.

Throws:

NoSuchMethodException - if the getter for the defined property does not exist

SecurityException - if the getter for the defined property cannot be accessed
