Member Function Documentation

const int mirror::element_traversal_info::container_index

(

void

)

const [inline]

Returns the container index.

This function returns the index of the container that the currently traversed element belongs to. This function returns zero for the simple and the single-value containers.

const int mirror::element_traversal_info::elements_done

(

void

)

const [inline]

Returns the count of already processed elements.

This function returns the count of element which have already been processed during this traversal not including the current element. i.e. for the first element this value is zero
