Returns the Set
view of this BitVector
.
BitVector
does not perform well for scanning,
so this method is for efficient scanning (while this set is
not modified). Also, having the Set
object
with actual Tag objects inside may be sometimes easier
to handle. Change to the set returned by this method
will NOT be reflected in this bit vector and vice versa.
This method checks if this BitVector
has been modified after the previous call to this method,
and if not, returns the Set
instance returned
by the previous call. If this BitVector
has been
modified since the previous call, or there has never been
such a call, then it returns a new copy of the Set
synchronized with the current state of this BitVector
.
So if the Set
instance returned by a previous
call to this method has been modified while this
BitVector
itself has not been modified, this
method will return the same BitVector
. In general,
the Set
instance returned by this method should
not be modified.
pBitAssignedTags
- the mapping from integer indexes to
Tag objects, used to create the Set
view of
this TagVector.
Set
view of this TagVector.BriggsSet toBriggsSet()
Returns the BriggsSet view of this BitVector
.
