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 ...

token - the initial token for the primitive
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
