Namespaces | |
namespace | escript |
namespace | escript::DataTypes |
Contains the types to represent Shapes, Regions, RegionLoop ranges and vectors of data as well as the functions to manipulate them. | |
Typedefs | |
typedef DataVector | escript::DataTypes::ValueType |
Vector to store underlying data. | |
typedef std::vector< int > | escript::DataTypes::ShapeType |
The shape of a single datapoint. | |
typedef std::vector< std::pair < int, int > > | escript::DataTypes::RegionType |
typedef std::vector< std::pair < int, int > > | escript::DataTypes::RegionLoopRangeType |
Functions | |
int | escript::DataTypes::noValues (const DataTypes::ShapeType &shape) |
Calculate the number of values in a datapoint with the given shape. | |
std::string | escript::DataTypes::shapeToString (const DataTypes::ShapeType &shape) |
Return the given shape as a string. | |
DataTypes::ShapeType | escript::DataTypes::getResultSliceShape (const DataTypes::RegionType ®ion) |
Determine the shape of the specified slice region. | |
DataTypes::RegionType | escript::DataTypes::getSliceRegion (const DataTypes::ShapeType &shape, const boost::python::object &key) |
Determine the region specified by the given python slice object. | |
DataTypes::RegionLoopRangeType | escript::DataTypes::getSliceRegionLoopRange (const DataTypes::RegionType ®ion) |
Modify region to copy from in order to deal with the case where one range in the region contains identical indexes, eg: <<1,1><0,3><0,3>> This situation implies we want to copy from an object with rank greater than that of this object. eg: we want to copy the values from a two dimensional slice out of a three dimensional object into a two dimensional object. We do this by taking a slice from the other object where one dimension of the slice region is of size 1. So in the above example, we modify the above region like so: <<1,2><0,3><0,3>> and take this slice. | |
int | escript::DataTypes::getRank (const DataTypes::ShapeType &shape) |
Return the rank (number of dimensions) of the given shape. | |
DataTypes::ValueType::size_type | escript::DataTypes::getRelIndex (const DataTypes::ShapeType &shape, DataTypes::ValueType::size_type i) |
Compute the offset (in 1D vector) of a given subscript with a shape. | |
DataTypes::ValueType::size_type | escript::DataTypes::getRelIndex (const DataTypes::ShapeType &shape, DataTypes::ValueType::size_type i, DataTypes::ValueType::size_type j) |
Compute the offset (in 1D vector) of a given subscript with a shape. | |
DataTypes::ValueType::size_type | escript::DataTypes::getRelIndex (const DataTypes::ShapeType &shape, DataTypes::ValueType::size_type i, DataTypes::ValueType::size_type j, DataTypes::ValueType::size_type k) |
Compute the offset (in 1D vector) of a given subscript with a shape. | |
DataTypes::ValueType::size_type | escript::DataTypes::getRelIndex (const DataTypes::ShapeType &shape, DataTypes::ValueType::size_type i, DataTypes::ValueType::size_type j, DataTypes::ValueType::size_type k, DataTypes::ValueType::size_type m) |
Compute the offset (in 1D vector) of a given subscript with a shape. | |
bool | escript::DataTypes::checkShape (const ShapeType &s1, const ShapeType &s2) |
Test if two shapes are equal. | |
std::string | escript::DataTypes::createShapeErrorMessage (const std::string &messagePrefix, const DataTypes::ShapeType &other, const DataTypes::ShapeType &thisShape) |
Produce a string containing two shapes. | |
void | escript::DataTypes::copySlice (ValueType &left, const ShapeType &leftShape, ValueType::size_type leftOffset, const ValueType &other, const ShapeType &otherShape, ValueType::size_type otherOffset, const RegionLoopRangeType ®ion) |
Copy a data slice specified by the given region and offset from the "other" view into the "left" view at the given offset. | |
void | escript::DataTypes::copySliceFrom (ValueType &left, const ShapeType &leftShape, ValueType::size_type leftOffset, const ValueType &other, const ShapeType &otherShape, ValueType::size_type otherOffset, const RegionLoopRangeType ®ion) |
Copy data into a slice specified by the given region and offset in the left vector from the other vector at the given offset. | |
void | escript::DataTypes::pointToStream (std::ostream &os, const ValueType::ElementType *data, const ShapeType &shape, int offset, bool needsep=true, const std::string &sep=",") |
Display a single value (with the specified shape) from the data. | |
std::string | escript::DataTypes::pointToString (const ValueType &data, const ShapeType &shape, int offset, const std::string &prefix) |
Display a single value (with the specified shape) from the data. | |
void | escript::DataTypes::copyPoint (ValueType &dest, ValueType::size_type doffset, ValueType::size_type nvals, const ValueType &src, ValueType::size_type soffset) |
Copy a point from one vector to another. Note: This version does not check to see if shapes are the same. | |
Variables | |
static const int | escript::DataTypes::maxRank = 4 |
The maximum number of dimensions a datapoint can have. | |
static const ShapeType | escript::DataTypes::scalarShape |
Use this instead of creating empty shape objects for scalars. |
