Detailed Description

Represent a continuous scalar range of values.

vtkm::Range is a helper class for representing a range of floating point values from a minimum value to a maximum value. This is specified simply enough with a Min and Max value.

Range also contains several helper functions for computing and maintaining the range.

Constructor & Destructor Documentation

Range() [1/4]

vtkm::Range::Range ( )

inline

Construct a range with a given minimum and maximum.

If no minimum or maximum is given, the range will be empty.

Range() [2/4]

vtkm::Range::Range ( const Range &  )

default

Range() [3/4]

vtkm::Range::Range ( Range &&  )

default

Range() [4/4]

template<typename T1 , typename T2 >

vtkm::Range::Range ( const T1 &  min, const T2 &  max  )

inline

Member Function Documentation

Center()

vtkm::Float64 vtkm::Range::Center ( ) const

inline

Returns the center of the range.

Center computes the middle value of the range. If the range is empty, NaN is returned.

Contains()

template<typename T >

bool vtkm::Range::Contains ( const T &  value ) const

inline

Determines if a value is within the range.

Contains returns true if the give value is within the range, false otherwise. Contains treats the min and max as inclusive. That is, if the value is exactly the min or max, true is returned.

Include() [1/2]

template<typename T >

void vtkm::Range::Include ( const T &  value )

inline

Expand range to include a value.

This version of Include expands the range just enough to include the given value. If the range already includes this value, then nothing is done.

Include() [2/2]

void vtkm::Range::Include ( const vtkm::Range &  range )

inline

Expand range to include other range.

This version of Include expands this range just enough to include that of another range. Essentially it is the union of the two ranges.

Intersection()

vtkm::Range vtkm::Range::Intersection ( const vtkm::Range &  otherRange ) const

inline

Return the intersection of this and another range.

IsNonEmpty()

bool vtkm::Range::IsNonEmpty ( ) const

inline

Determine if the range is valid (i.e.

has at least one valid point).

IsNonEmpty return true if the range contains some valid values between Min and Max. If Max is less than Min, then no values satisfy the range and IsNonEmpty returns false. Otherwise, return true.

IsNonEmpty assumes Min and Max are inclusive. That is, if they are equal then true is returned.

Length()

vtkm::Float64 vtkm::Range::Length ( ) const

inline

Returns the length of the range.

Length computes the distance between the min and max. If the range is empty, 0 is returned.

operator!=()

bool vtkm::Range::operator!= ( const vtkm::Range &  otherRange ) const

inline

operator+()

vtkm::Range vtkm::Range::operator+ ( const vtkm::Range &  otherRange ) const

inline

Operator for union

operator=() [1/2]

vtkm::Range& vtkm::Range::operator= ( const vtkm::Range &  src )

default

operator=() [2/2]

vtkm::Range& vtkm::Range::operator= ( vtkm::Range &&  src )

default

operator==()

bool vtkm::Range::operator== ( const vtkm::Range &  otherRange ) const

inline

Union()

vtkm::Range vtkm::Range::Union ( const vtkm::Range &  otherRange ) const

inline

Return the union of this and another range.

This is a nondestructive form of Include.

Member Data Documentation

Max

vtkm::Float64 vtkm::Range::Max

Tha maximum value of the range (inclusive).

Min

vtkm::Float64 vtkm::Range::Min

The minumum value of the range (inclusive).
