public class Multiply

extends AbstractAssignment

This class provides an implementation for the primitive \multiply.

The Primitive \advance

This primitive implements an assignment. The variable given as next tokens is multiplied by the quantity given after the optional by.

Syntax

   ⟨multiply⟩
     → ⟨optional prefix⟩ \multiply ⟨multiplyable⟩

   ⟨multiplyable⟩
     → ⟨integer variable⟩ ⟨optional by⟩ ⟨8-bit number⟩
      |  ⟨dimen variable⟩ ⟨optional by⟩ ⟨8-bit number⟩
      |  ⟨glue variable⟩ ⟨optional by⟩ ⟨8-bit number⟩
      |  ⟨muglue variable⟩ ⟨optional by⟩ ⟨8-bit number⟩

   ⟨optional prefix⟩
     →
      |  \global ⟨optional prefix⟩

   ⟨optional by⟩
     → [by]
      |  ⟨optional spaces⟩
   

Examples

    \multiply\count12 345

Multiply

public Multiply(java.lang.String name)

Creates a new object.

Parameters:

name - the name for debugging

assign

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

Description copied from class: AbstractAssignment

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:

InterpreterException - in case of an error
