Member Function Documentation

◆ Density() [1/2]

static double Density ( const std::string &  _material)
static

Return the density of the given material name, or -1 if the material is not found.

Parameters
[in]_materialName of the material, See Type.
Returns
Matching density if found, otherwise -1.

◆ Density() [2/2]

static double Density ( const Type  _material)
static

Return the density of a material.

Parameters
[in]_materialType of the material, See Type.
Returns
Matching density if found, otherwise -1.

◆ Materials()

static const std::map<Type, double>& Materials ( )
static

Accessor for retrieving density entries.

Returns
List of entries.

◆ Nearest()

static std::tuple<Type, double> Nearest ( const double  _value,
const double  _epsilon = std::numeric_limits< double >::max() 
)
static

Return the material with the closest density value within _epsilon, or MATERIAL_TYPE_END if not found.

Parameters
[in]_valueDensity value of entry to match.
[in]_epsilonAllowable range of difference between _value, and a material's density.
Returns
A tuple where the first element is the Type, and the second the density. A value of {MATERIAL_TYPE_END, -1} is returned on error.

◆ NearestMaterial()

static Type NearestMaterial ( const double  _value,
const double  _epsilon = std::numeric_limits< double >::max() 
)
static

Return the material with the closest density value within _epsilon, or MATERIAL_TYPE_END if not found.

Parameters
[in]_valueDensity value of entry to match.
[in]_epsilonAllowable range of difference between _value, and a material's density.
Returns
The nearest material type. MATERIAL_TYPE_END on error.
