UA_REFTREE_INITIAL_SIZE

#define UA_REFTREE_INITIAL_SIZE   16

RefTree.

A RefTree is a sorted set of NodeIds that ensures we consider each node just once. It holds a single array for both the ExpandedNodeIds and the entries of a tree-structure for fast lookup. A single realloc operation (with some pointer repairing) can be used to increase the capacity of the RefTree.

When the RefTree is complete, the tree-part at the end of the targets array can be ignored / cut away to use it as a simple ExpandedNodeId array.

The layout of the targets array is as follows:

| Targets [ExpandedNodeId, n times] | Tree [RefEntry, n times] |

		const UA_ReadValueId *	id,
		UA_DataValue *	v
	)

Check Information Model Consistency.

Read a node attribute in the context of a "checked-out" node. So the attribute will not be copied when possible. The variant then points into the node and has UA_VARIANT_DATA_NODELETE set.

readValueAttribute()

		size_t	targetArrayDimensionsSize,
		const UA_UInt32 *	targetArrayDimensions,
		const UA_Variant *	value,
		const UA_NumericRange *	range,
		const char **	reason
	)

Test whether the value matches a variable definition given by.

• datatype
• valueranke
• array dimensions. Sometimes it can be necessary to transform the content of the value, e.g. byte array to bytestring or uint32 to some enum. If editableValue is non-NULL, we try to create a matching variant that points to the original data.

The reason is set whenever the return value is false

compatibleDataTypes()

UA_Boolean compatibleDataTypes	(	UA_Server *	server,
		const UA_NodeId *	dataType,
		const UA_NodeId *	constraintDataType
	)

Is the DataType compatible.

adjustValueType()

void adjustValueType	(	UA_Server *	server,
		UA_Variant *	value,
		const UA_NodeId *	targetDataTypeId
	)

Set to the target type if compatible.

compatibleValueDataType()

UA_Boolean compatibleValueDataType	(	UA_Server *	server,
		const UA_DataType *	dataType,
		const UA_NodeId *	constraintDataType
	)

Is the Value compatible with the DataType? Can perform additional checks compared to compatibleDataTypes.

AddNodes Begin and Finish.

Creates a new node in the nodestore.

AddNode_addRefs()

		UA_Session *	session,
		const UA_NodeId *	nodeId,
		const UA_NodeId *	parentNodeId,

	)

Check the reference to the parent node; Add references.

AddNode_finish()

UA_StatusCode AddNode_finish	(	UA_Server *	server,
		UA_Session *	session,
		const UA_NodeId *	nodeId
	)

Type-check type-definition; Run the constructors.

UA_Server_initNS0()

UA_StatusCode UA_Server_initNS0

(

UA_Server *

UA_NODESTORE_GETFROMREF()

const UA_Node * UA_NODESTORE_GETFROMREF	(	UA_Server *	server,
