public class Atopwithdelims

extends AbstractTeXDelimiter

This class provides an implementation for the primitive \atopwithdelims.

The Math Primitive \atopwithdelims

The math primitive \atopwithdelims arranges that the material in the math group before it is typeset above the material after the primitive. The two parts are not separated by a line. 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

    ⟨atopwithdelims⟩
       → ⟨math material⟩ \atopwithdelims ... ⟨math material⟩ 

Examples

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

Atopwithdelims

public Atopwithdelims(java.lang.String name)

Creates a new object.

Parameters:

name - the name for tracing and debugging

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
