      extended by org.extex.unit.tex.typesetter.paragraph.Indent
All Implemented Interfaces:
java.io.Serializable, Code

public class Indent
extends AbstractCode

This class provides an implementation for the primitive \indent.

The Primitive \indent

The primitive \indent ensures that the further processing appears in horizontal mode and inserts horizontal spacing in the width of the dimen register \parindent.

Note that the spacing is inserted in any case. Thus several successive invocations lead to more spacing. This can even happen in the middle of a paragraph.

Syntax

The formal description of this primitive is the following:
    ⟨indent⟩
       → \indent  

Examples

    \indent
