Member Enumeration Documentation

enum StaticAnalysis::Properties

Properties that allow optimisation regarding sorting or not.

The values are OR'd as flags, so they must be distinct bits

Enumerator:

DOCORDER	Results are returned in document order.
PEER	Results do not appear in the descendants of other results.
SUBTREE	Results are members of the set of descendants of the context node.
GROUPED	Results are grouped by the document they come from.
SAMEDOC	Results are from the same document as the context node.
ONENODE	Only ever returns one node.
SELF	Only ever returns the context node.
FORWARDREF	This is a forward reference for a global variable that is declared later.
UNDEFINEDVAR	This is a variable that has been undefined.
