public class Mkern
extends AbstractMathCode

This class provides an implementation for the primitive \mkern.

The Math Primitive \mkern

The math primitive \mkern inserts some kerning in math mode. The amount of space to be inserted is measured in math units.

Syntax

The formal description of this primitive is the following:

    ⟨mkern⟩
       → \mkern ⟨mudimen⟩ 

Examples

    \mkern 12mu

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:

HelpingException - in case of an error

ConfigurationException - in case of an configuration error

TypesetterException - in case of an error in the typesetter
