public class Integer
extends AbstractAssignment

This class provides an implementation for the primitive \integer.

The Primitive \integer

The primitive \integer can be used to define a control sequence as alias for an integer register. The control sequence can be used wherever a count is expected afterwards.

The primitive \integer is an assignment. Thus the settings of \afterassignment and \globaldefs are applied.

The prefix \global can be used to make the assignment to the new control sequence global instead of the group-local assignment which is the default.

Syntax

The formal description of this primitive is the following:

    ⟨integer⟩
      → ⟨optional prefix⟩ \integer ⟨control sequence⟩ ⟨equals⟩ ⟨number⟩

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

Examples

    \integer\abc=45  

    \integer\abc 33  

    \integer\abc=-12

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
