public class Pdffontname

extends AbstractPdftexCode

implements ExpandableCode, Theable, TokensConvertible

This class provides an implementation for the primitive \pdffontname.

The PDF Primitive \pdffontname

This primitive expands to the name of the font as used in PDF. For instance if a font is addressed as /F12 then this primitive expands to 12.

Syntax

    ⟨pdffontname⟩
       → \pdffontname ⟨font⟩ 

Examples

    \font\f cmr12
    \pdffontname \f

Constant Field Values

Pdffontname

public Pdffontname(java.lang.String name)

Creates a new object.

Parameters:

name - the name for tracing and debugging

convertTokens

public Tokens convertTokens(Context context,
                            TokenSource source,
                            Typesetter typesetter)
                     throws InterpreterException

Description copied from interface: TokensConvertible

This method converts a register into tokens. It might be necessary to read further tokens to determine which value to use. For instance an additional register number might be required. In this case the additional arguments Context and TokenSource can be used.

Specified by:

convertTokens in interface TokensConvertible

Parameters:

context - the interpreter context

source - the source for new tokens

typesetter - the typesetter to use for conversion

Returns:

the converted value

Throws:

InterpreterException - in case of an error

TokensConvertible.convertTokens( de.dante.extex.interpreter.context.Context, de.dante.extex.interpreter.TokenSource, de.dante.extex.typesetter.Typesetter)

execute

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

Description copied from interface: Code

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

Throws:

InterpreterException

See Also:

Code.execute( de.dante.extex.interpreter.Flags, de.dante.extex.interpreter.context.Context, de.dante.extex.interpreter.TokenSource, de.dante.extex.typesetter.Typesetter)

expand

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

Description copied from interface: ExpandableCode

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:

InterpreterException - in case of an error

See Also:

ExpandableCode.expand( de.dante.extex.interpreter.Flags, de.dante.extex.interpreter.context.Context, de.dante.extex.interpreter.TokenSource, de.dante.extex.typesetter.Typesetter)

the

public Tokens the(Context context,
                  TokenSource source,
                  Typesetter typesetter)
           throws InterpreterException

Description copied from interface: Theable

This method is the getter for the description of the primitive.

Specified by:

the in interface Theable

Parameters:

context - the interpreter context

source - the source for further tokens to qualify the request

typesetter - the typesetter to use

Returns:

the description of the primitive as list of Tokens

Throws:

InterpreterException - in case of an error
