Detailed Description

template<class T, int SIZE>
class vigra::TinyVector< T, SIZE >

Class for fixed size vectors.

This class contains an array of size SIZE of the specified VALUETYPE. The interface conforms to STL vector, except that there are no functions that change the size of a TinyVector.

Arithmetic operations on TinyVectors are defined as component-wise applications of these operations. Addition and subtraction of two TinyVectors (+=, -=, +, -, unary -), multiplication and division of an TinyVector with a double, and NumericTraits/PromoteTraits are defined, so that TinyVector fulfills the requirements of Linear Algebra.

VIGRA algorithms typically use vigra::VectorAccessor to access TinyVectors as a whole, or specific components of them.

Constructor & Destructor Documentation

◆ TinyVector() [1/13]

TinyVector ( value_type const &  initial)
explicit

Construction with constant value.

Initializes all vector elements with the given value.

◆ TinyVector() [2/13]

TinyVector ( lemon::Invalid const &  )

Construction from lemon::Invalid.

Initializes all vector elements with -1.

◆ TinyVector() [3/13]

TinyVector ( Diff2D const &  initial)
explicit

Construction with Diff2D.

Use only when SIZE == 2.

◆ TinyVector() [4/13]

TinyVector ( value_type const &  i1,
value_type const &  i2 
)

Construction with explicit values. Call only if SIZE == 2

◆ TinyVector() [5/13]

TinyVector ( value_type const &  i1,
value_type const &  i2,
value_type const &  i3 
)

Construction with explicit values. Call only if SIZE == 3

TinyVector ( U const *  data)
explicit

Constructor from C array.

◆ TinyVector() [12/13]

TinyVector ( const_pointer  data,
ReverseCopyTag   
)
explicit

Constructor by reverse copy from C array.

Usage:

TinyVector<int, 3> v(1,2,3);
TinyVector<int, 3> reversed(v.begin(), TinyVector<int, 3>::ReverseCopy);

◆ TinyVector() [13/13]

TinyVector ( TinyVectorBase< U, SIZE, DATA, DERIVED > const &  r)

Copy with type conversion.

Member Function Documentation

◆ operator=() [1/4]

TinyVector& operator= ( TinyVector< T, SIZE > const &  r)

Copy assignment.

◆ operator=() [2/4]

TinyVector& operator= ( TinyVectorBase< U, SIZE, DATA, DERIVED > const &  r)

Copy assignment with type conversion.

◆ operator=() [3/4]

TinyVector& operator= ( Diff2D const &  r)

Assignment from Diff2D.

Use only when SIZE == 2.

◆ operator=() [4/4]

TinyVector& operator= ( value_type const &  v)

Assignment from scalar. Will set all entries to the given value.

◆ copy()

TinyVector& copy ( TinyVectorBase< U, USIZE, DATA, DERIVED > const &  r)

Copy from a TinyVector with a different number of elements.

Only the first min(SIZE, USIZE) elements are copied.
