Member Function Documentation

getBlockGeometry()

template<typename T >

BlockGeometry< T, 2 > & olb::BlockIndicatorF2D< T >::getBlockGeometry

(

)

Get underlying block geometry structure.

Returns

_blockGeometryStructure

Definition at line 40 of file blockIndicatorBaseF2D.hh.

{
  return _blockGeometryStructure;
}

Here is the caller graph for this function:

getMax()

template<typename T >

virtual Vector< int, 2 > olb::BlockIndicatorF2D< T >::getMax ( )

pure virtual

Returns max lattice position of the indicated subset's bounding box.

Implemented in olb::BlockIndicatorFfromIndicatorF2D< T >, olb::BlockIndicatorFfromSmoothIndicatorF2D< T, HLBM >, olb::BlockIndicatorMaterial2D< T >, olb::BlockIndicatorIdentity2D< T >, and olb::BlockIndicatorBoundaryNeighbor2D< T >.

getMin()

template<typename T >

virtual Vector< int, 2 > olb::BlockIndicatorF2D< T >::getMin ( )

pure virtual

Returns min lattice position of the indicated subset's bounding box.

Implemented in olb::BlockIndicatorFfromIndicatorF2D< T >, olb::BlockIndicatorFfromSmoothIndicatorF2D< T, HLBM >, olb::BlockIndicatorMaterial2D< T >, olb::BlockIndicatorIdentity2D< T >, and olb::BlockIndicatorBoundaryNeighbor2D< T >.

isEmpty()

template<typename T >

bool olb::BlockIndicatorF2D< T >::isEmpty ( )

virtual

Returns true only if the indicated domain subset is empty.

May return false even if the indicated domain subset is in fact empty. Primarily implemented to minimize block accesses if an empty domain can be inferred by e.g. BlockGeometryStatistics2D data.

i.e. only override this method if the domain can be checked for emptyness in an efficient fashion.

Reimplemented in olb::BlockIndicatorMaterial2D< T >.

Definition at line 78 of file blockIndicatorBaseF2D.hh.

{
  // There is no way to determine domain emptyness in a fashion that is both
  // generic and efficient.
  return false;
}

operator()() [1/3]

template<typename T >

bool olb::BlockIndicatorF2D< T >::operator()

(

const int

input[]

)

Block indicator specific function operator overload.

The boolean return value of operator()(T output[], S input[]) describes the call's success and by convention must not describe the indicated domain.

Returns

Domain indicator i.e. true iff the input lies within the described subset.

Definition at line 46 of file blockIndicatorBaseF2D.hh.

{
  bool output{};
  if (_cachedData == nullptr) {
    this->operator()(&output, input);
  }
  else {
    _cachedData->get(input);
  }
  return output;
}

operator()() [2/3]

template<typename T >

bool olb::BlockIndicatorF2D< T >::operator()	(	int	iX,
		int	iY )

Definition at line 59 of file blockIndicatorBaseF2D.hh.

{
  int latticeR[2] { iX, iY };
  return this->operator()(latticeR);
}

operator()() [3/3]

template<typename T >

bool olb::BlockIndicatorF2D< T >::operator()

(

LatticeR< 2 >

loc

)

Definition at line 66 of file blockIndicatorBaseF2D.hh.

{
  return operator()(loc[0], loc[1]);
}

setCache()

template<typename T >

void olb::BlockIndicatorF2D< T >::setCache

(

const BlockData< 2, T, bool > &

cache

)

Set bool-mask cache to be used by indicator operator overloads.

Definition at line 72 of file blockIndicatorBaseF2D.hh.

{
  _cachedData = &cache;
}
