public interface TwoDimensional

TwoDimensional is an interface for any item which can be navigated in two dimensions, such as a List of Lists. In short, it allows one to find a position within this object.

There are two basic kinds of two dimensional objects.

1. One has a type of List<List<Object>>. The major dimension's value indicates the index of the "inner list" within the "outer list" while the minor dimension's value indicates the index of the object within an "inner list."
2. One has a type of List<ObjectWithLengthMethod as in List<String>. The major dimension's value indicates the index within the list while the minor dimension's value indicates how far into that length-object a position is (e.g. how many characters into a String is a position).

Not all two dimensional objects are rectangular, so the valid values of the minor dimension depends on the major dimension.

Modifier and Type	Interface	Description
static class	TwoDimensional.Bias	Determines whether to add 1 when the end of an inner list is reached

Method Detail

position

TwoDimensional.Position position(int major,
                                 int minor)

Creates a two dimensional position in some entity (e.g. area, list of lists, list of some object with length) where the major 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.

offsetToPosition

TwoDimensional.Position offsetToPosition(int offset,
                                         TwoDimensional.Bias bias)

Creates a two dimensional position in some entity (e.g. area, list of lists, list of some object with length) where the offset value is an absolute position in that entity.
