public class Mathchar
extends AbstractTeXMathCode
implements MathCodeConvertible

This class provides an implementation for the primitive \mathchar.

The Math Primitive \mathchar

The primitive \mathchar inserts a mathematical character consisting of a math class and a character code into the current math list. This is supposed to work in math mode only.

TODO missing documentation

Syntax

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

Examples

    \mathchar"041  
    \mathchar{ordinary 0 `A}

Method Detail

convertMathCode

public MathCode convertMathCode(Context context,
                                TokenSource source,
                                Typesetter typesetter)
                         throws InterpreterException
Description copied from interface: MathCodeConvertible
This method converts an implementing class into a MathCode. It might be necessary to read further tokens to determine which value to use. For instance an additional register number might be required. In this case the additional arguments Context and TokenSource can be used.

Specified by:
convertMathCode in interface MathCodeConvertible
Parameters:
context - the interpreter context
source - the source for new tokens
typesetter - the typesetter to use for conversion
Returns:
the converted value
Throws:
InterpreterException - in case of an error

MathCodeConvertible.convertMathCode( de.dante.extex.interpreter.context.Context, de.dante.extex.interpreter.TokenSource, de.dante.extex.typesetter.Typesetter)

execute

public void execute(Flags prefix,
                    Context context,
                    TokenSource source,
                    Typesetter typesetter)
             throws InterpreterException
Description copied from interface: Code
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
Throws:
InterpreterException
