Detailed Description

template<int SIZE, typename T>
class openvdb::v9_0::math::Tuple< SIZE, T >

A base class for homogenous tuple types

using ValueType = T

Constructor & Destructor Documentation

Tuple ( )

default

Trivial constructor, the Tuple is NOT initialized

Note

destructor, copy constructor, assignment operator and move constructor are left to be defined by the compiler (default)

Tuple ( Tuple< src_size, src_valtype > const &  src )

inlineexplicit

Conversion constructor.

Tuples with different value types and different sizes can be interconverted using this member. Converting from a larger tuple results in truncation; converting from a smaller tuple results in the extra data members being zeroed out. This function assumes that the integer 0 is convertible to the tuple's value type.
