public class Fontname
extends AbstractCode
implements ExpandableCode

This class provides an implementation for the primitive \fontname.

The Primitive \fontname

The primitive \fontname can be used to retrieve the name of a font. It takes a font specification as argument. It expands to the name of the font. If this font is not loaded at its design size then the actual size is appended after the tokens at . All tokens produced this way are other tokens except of the spaces. This means that even the letters are of category other.

Syntax

The formal description of this primitive is the following:
    ⟨fontname⟩
       → \fontname ⟨font⟩  

Example

  \font\myFont=cmr12
  \fontname\myfont
  ⇒ cmr12
 
 \font\myFont=cmr12 at 24pt
 \fontname\myfont
 ⇒ cmr12 at 24pt

Field Summary
protected static long serialVersionUID
          The constant serialVersionUID contains the id for serialization.
 
Constructor Summary
Fontname(CodeToken token)
          Creates a new object.
 
Method Summary
 void execute(Flags prefix, Context context, TokenSource source, Typesetter typesetter)
          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.
 void expand(Flags prefix, Context context, TokenSource source, Typesetter typesetter)
          This method takes the first token and expands it.

Creates a new object.

Parameters:
token - the initial token for the primitive
Method Detail

execute

public void execute(Flags prefix,
                    Context context,
                    TokenSource source,
                    Typesetter typesetter)
             throws HelpingException,
                    TypesetterException
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
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

expand

public void expand(Flags prefix,
                   Context context,
                   TokenSource source,
                   Typesetter typesetter)
            throws HelpingException,
                   TypesetterException
This method takes the first token and expands it. The result is placed on the stack. This means that expandable code does one step of expansion and puts the result on the stack. To expand a token it might be necessary to consume further tokens.

Specified by:
expand in interface ExpandableCode
Parameters:
prefix - the prefix flags controlling the expansion
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
