Detailed Description

Defines a collection of elements that define filtering criteria.

Each element in the collection describes an operator and an array of operands to be used by the operator. See OpcUa_FilterOperator for a description of the operators that can be used in a ContentFilter. The filter is evaluated by evaluating the first entry in the element array starting with the first operand in the operand array. The operands of an element may contain References to subelements resulting in the evaluation continuing to the referenced elements in the element array. If an element cannot be traced back to the starting element it is ignored. Extra operands for any operator shall result in an error.
