DESCRIPTION
"The view tree database. This contains information about the
subtrees of MIB views known to this SNMPv2 entity. Note that
a MIB view which has no subtrees defined for it has no
entries in this table.
Each MIB view is defined by two collections of view subtrees:
the included view subtrees, and the excluded view subtrees.
Every such subtree, both included and excluded, is defined in
this table.
To determine if a particular object instance is in a
particular MIB view, compare the object instance's OBJECT
IDENTIFIER with each of the MIB view's active entries
in this table. If none match, then the object instance is
not in the MIB view. If one or more match, then the object
instance is included in, or excluded from, the MIB view
according to the value of viewTreeType in the entry whose
value of viewTreeSubTree has the most sub-identifiers. If
multiple entries match and have the same number of
sub-identifiers, then the lexicographically greatest instance
of viewTreeType among those which match determines the inclusion
or exclusion.
An object instance's OBJECT IDENTIFIER X matches an active
entry in this table when the number of sub-identifiers in X
is at least as many as in the value of viewTreeSubTree for
the entry, and each sub-identifier in the value of
viewTreeSubTree matches its corresponding sub-identifier in X.
Two sub-identifiers match either if the corresponding bit of
viewMask is zero (the 'wild card' value), or if they are equal.
Due to this 'wild card' capability, we introduce the term, a
'family' of view subtrees, to refer to the set of subtrees
defined by a particular combination of values of
viewTreeSubTree and viewTreeMask. In the case where no
'wild card' is defined in viewTreeMask, the family of view
subtrees reduces to a single view subtree."
