Class Fontname

      org.extex.unit.tex.font.Fontname

All Implemented Interfaces:

java.io.Serializable, Code, ExpandableCode

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

    ⟨fontname⟩
       → \fontname ⟨font⟩  

Example

  \font\myFont=cmr12
  \fontname\myfont
  ⇒ cmr12
 

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

Fontname

public Fontname(CodeToken token)

Creates a new object.

Parameters:

token - the initial token for the primitive

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
