Package jjparse.input

Class Input.Position

java.lang.Object

jjparse.input.Input.Position

Direct Known Subclasses:

CharacterInput.CodePointPosition

Enclosing class:

Input<T>

public abstract class Input.Position
extends Object

Represents an offset within this Input. Since the unit of this offset depends on the element type of this Input, this class depends on the specific Input instance. Also note, that this offset may not reflect the Input<T>.Position as it is perceived by the user. This is, for example, the case for Inputs of Characters, where up to two Characters may form a single unicode code point. It is up to the implementation of the respective Input to interpret this offset accordingly.
