public class Textstyle
extends AbstractMathCode

This class provides an implementation for the primitive \textstyle.

The Math Primitive \textstyle

The math primitive \textstyle arranges that the following material in the current math group is typeset in text style regardless of the style determined so far. This mean that for instance a subscript can be forced to be typeset in text style.

The math style influences the size and placement of glyphs as well an the spacing between them.

If used outside of math mode an error is raised.

Syntax

The formal description of this primitive is the following:

    ⟨textstyle⟩
       → \textstyle  

Examples

    \textstyle

This method takes the first token and executes it. The result is placed on the stack. This operation might have side effects. To execute a token it might be necessary to consume further tokens.

Specified by:

execute in interface Code

Overrides:

execute in class AbstractCode

Parameters:

prefix - the prefix controlling the execution

context - the interpreter context

source - the token source

typesetter - the typesetter

Throws:

TypesetterException - in case of an error in the typesetter

MissingMathException
