public TwoLevelNavigator(java.util.function.IntSupplier elemCount,
java.util.function.IntUnaryOperator elemLength)
TwoDimensional.Position within a two dimensional object.elemCount - a supplier that returns the number of "inner lists" within an "outer list" (see
TwoDimensional for clarification). For example,
List::sizeelemLength - a function that, given the index of an "inner list," returns either the size of that "inner
list" of the length of that inner object.public TwoDimensional.Position position(int major, int minor)
TwoDimensionalmajor value is the index within the outer list) and the minor
value is either the index within the inner list or some amount of length in a list of objects that have length.position in interface TwoDimensionalpublic TwoDimensional.Position offsetToPosition(int offset, TwoDimensional.Bias bias)
TwoDimensionaloffset value is an absolute position in that entity.offsetToPosition in interface TwoDimensional
