Detailed Description

The base class for all types of sparse tensor levels.

It provides interfaces to query the loop range (see peekRangeAt) and look up the coordinates (see peekCrdAt).

Peeks the lower and upper bound to fully traverse the level with the given position parentPos, see SparseTensorIterator::getCurPostion(), that the immediate parent level is current at.

Returns a pair of values for posLo and loopHi respectively.

For a dense level, the posLo is the linearized position at beginning, while loopHi is the largest coordinate, it also implies that the smallest coordinate to start the loop is 0.

For a sparse level, [posLo, loopHi) specifies the range of index pointer to load coordinate from the coordinate buffer.
