public class Mathchardef
extends AbstractAssignment

This class provides an implementation for the primitive \mathchardef.

The Math Primitive \mathchardef

The math primitive \mathchardef defines a control sequence or active character as equivalent to a math character.

TODO missing documentation

Syntax

The formal description of this primitive is the following:

    ⟨mathchardef⟩
       → \mathchardef ...  

Examples

    \mathchardef\alpha ...

Method Detail

assign

public void assign(Flags prefix,
                   Context context,
                   TokenSource source,
                   Typesetter typesetter)
            throws HelpingException,
                   TypesetterException

The method assign is the core of the functionality of execute(). This method is preferable to execute() since the execute() method provided in this class takes care of \afterassignment and \globaldefs as well.

Specified by:

assign in class AbstractAssignment

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

TypesetterException - in case of an error in the typesetter
