\inqmlmodule QtOpcUa
\brief The OPC UA ContentFilterElement.
\since QtOpcUa 5.13
\deprecated [6.9]
A content filter element contains an operator and operands.
There are four different operator types which contain literal values, references to
attributes of nodes or to other content filter elements.
A combination of one or more content filter elements makes a content filter which is used
by the server to filter data for the criteria defined by the content filter elements.
For example, the \c where clause of an event filter is a content filter which is used to decide
if a notification is generated for an event.
\code
QtOpcUa.FilterElement {
operator: QtOpcUa.FilterElement.GreaterThanOrEqual
firstOperand: QtOpcUa.SimpleAttributeOperand { ... }
secondOperand: QtOpcUa.LiteralOperand { ... }
}
\endcode
