Detailed Description

An irregular domain on an integer lattice.

IntVectSet represents an irregular region in an integer lattice SpaceDim-dimensional index space as an arbitrary collection of IntVects. A full set calculus is defined. Any IntVect or cell-centered Box can be fully represented as an IntVectSet. There is an iterator that provides access to the contents of an IntVectSet. IntVectSets are implicitly cell-centered. Intersection, union, and complement operations are defined for pairs of IntVectSets (and, by extension, an IntVectSet and an IntVect or an IntVectSet and a Box). The minimum Box of an IntVectSet is defined as the smallest Box that contains every IntVect in the IntVectSet.

The IntVects in an IntVectSet do not have a canonical ordering.

(

)

Modifies this IntVectSet to empty but leaves dense domain box unchanged.

This leaves unchanged the domain box for a dense IntVectSet - it only sets all bits to zero. So you can still do unions later (in the domain box) and not be converted to a tree representation. There is no difference from makeEmpty() for a tree IntVectSet

IntVectSet IntVectSet::chop	(	int	dir,
		int	chop_pnt
	)

Chop the IntVectSet at the chop_pnt index in the dir direction.

Returns one IntVectSet and modifies this IntVectSet. The union of the two is the original IntVectSet. This IntVectSet gets the IntVects with dir index >= chop_pnt, and the returned IntVectSet gets the IntVects with dir index < chop_pnt. It is an error if dir is invalid.

bool IntVectSet::contains

(

bool IntVectSet::contains_box

(

const Box &

b

)

const [inline]

same as contains(b)

References contains().

Vector<Box> IntVectSet::boxes

(

)

const

Returns a Vector<Box> representation of this IntVectSet.

The returned Boxes contain only the IntVects in this IntVectSet, so the union of the Boxes in the Vector == this IntVectSet.

void IntVectSet::compact

(

)

const

Optimize memory usage of this IntVectSet.

Attempts to optimize storage for IntVectSet. This will also optimize iteration through the IntVectSet later. Best to call it when you are no longer modifying the IntVectSet

int IntVectSet::linearSize

(

)

const

Returns the number of bytes in a linear representation of *this.

void IntVectSet::linearIn

const void *const

a_inBuf

Assumes a_outBuf is at least linearSize() bytes long.

bool IntVectSet::operator==

(

a_ivs

)

const

Returns true if this IntVectSet has the same IntVects as a_ivs.

bool IntVectSet::operator<

(

const IntVectSet &

a_ivs

)

const

Primary sorting criterion: being dense; if *this is dense and a_ivs is not, then *this is smaller, and vice versa. Secondary sorting criterion: operator< as defined on DenseIntVectSet or TreeIntVectSet. In a total tie, returns false.

These criteria might not seem natural, but that doesn't matter as the only reason for this operator is to support using IntVectSet as the key to an std::map.

void IntVectSet::printBoxes

(

std::ostream &

a_ostream

)

const

Writes a Vector<Box> representation to an output stream.
