Class LeftAlignmentProcessor

java.lang.Object

org.jfree.layouting.renderer.process.AbstractAlignmentProcessor

org.jfree.layouting.renderer.process.LeftAlignmentProcessor

All 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.

next

public RenderNode next()

Specified by:

next in interface TextAlignmentProcessor

Overrides:

next in class AbstractAlignmentProcessor

handleElement

protected int handleElement(int start,

Parameters:

start - the start index

count - the number of elements in the sequence

Returns:

true, if processing should be finished, false if more elements are needed for the line.
