Detailed Description

template<typename T>
class PxStrideIterator< T >

This class is used for iterating over arrays of elements that may have a larger element to element offset, called the stride, than the size of the element itself (non-contiguous).

The template parameter T denotes the type of the element accessed. The stride itself is stored as a member field so multiple instances of a PxStrideIterator class can have different strides. This is useful for cases were the stride depends on runtime configuration.

The stride iterator can be used for index based access, e.g.:

    PxStrideIterator<PxVec3> strideArray(...);
    for (unsigned i = 0; i < 10; ++i)
    {
        PxVec3& vec = strideArray[i];
        ...
    }

    PxStrideIterator<PxVec3> strideBegin(...);
    PxStrideIterator<PxVec3> strideEnd(strideBegin + 10);
    for (PxStrideIterator<PxVec3> it = strideBegin; it < strideEnd; ++it)
    {
        PxVec3& vec = *it;
        ...
    }

Two special cases:

• A stride of sizeof(T) represents a regular c array of type T.
• A stride of 0 can be used to describe re-occurrence of the same element multiple times.
