Class LeftAlignmentProcessor

Implemented Interfaces:
TextAlignmentProcessor
public class LeftAlignmentProcessor
extends AbstractAlignmentProcessor
Performs the left-alignment computations.

The inf-min-step creates the initial sequence of elements. The alignment processor now iterates over the sequence and produces the layouted line.

Elements can be split, splitting is a local operation and does not copy the children. Text splitting may produce a totally different text (see: TeX hyphenation system).

The process is iterative and continues unless all elements have been consumed.
