Class Fontname

org.extex.interpreter.type.AbstractCode
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
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

Method Summary |

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. |

expand(Flags prefix,
Context context,
TokenSource source,
Typesetter typesetter)
This method takes the first token and expands it. |

- 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 executioncontext
- the interpreter contextsource
- the token sourcetypesetter
- the typesetter
- Throws:
HelpingException
- in case of an error
TypesetterException
- in case of an error in the typesetter- See Also:

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 expansioncontext
- the interpreter contextsource
- the token sourcetypesetter
- the typesetter
- Throws:
HelpingException
- in case of an error
TypesetterException
- in case of an error in the typesetter- See Also:
