v_array< T > 模板类 参考

详细描述

template<class T>
class shogun::v_array< T >

Class v_array taken directly from JL's implementation.

Class v_array is a templated class used to store variable length arrays. Memory locations are stored as 'extents', i.e., address of the first memory location and address after the last member.

`begin', `end' and `end_array' handle the extent of the array. `end_array' is the address at the end of the space allocated for the array while `end' is the address at the end of the space actually filled with elements.

The class should be instantiated on the basis of the data type of the contained array, eg. v_array<float32_t> if one wants to store a float32_t* array.
