public class Abovewithdelims
extends AbstractTeXDelimiter

This class provides an implementation for the primitive \abovewithdelims.

The Math Primitive \abovewithdelims

The math primitive \abovewithdelims arranges that the material in the math group before it is typeset above the material after the primitive. The two parts are separated by a line of the width given. If the width is less than 0pt then no rule is drawn but the given height is left blank. The construction is enclosed in the delimiters given

If several primitives of type \above, \abovewithdelims, \atop, \atopwithdelims, \over, or \overwithdelims are encountered in the same math group then the result is ambiguous and an error is raised.

If the primitive is used outside of math mode then an error is raised.

Syntax

The formal description of this primitive is the following:
    ⟨abovewithdelims⟩
       → ⟨math material⟩ \abovewithdelims ... ⟨dimen⟩ ⟨math material⟩  

Examples

    {a\abovewithdelims\delimiter"123456\delimiter"123456 b}

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
