public class Pdflastannot
extends AbstractPdftexCode
implements Theable, CountConvertible

This class provides an implementation for the primitive \pdflastannot.

The PDF Primitive \pdflastannot

This primitive provides a read-only count register containing the number of the last annotation. If there is no last annotation then 0 is returned.

Syntax

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

Examples

    \count0=\pdflastannot

Method Detail

convertCount

public long convertCount(Context context,
                         TokenSource source,
                         Typesetter typesetter)
                  throws InterpreterException
Description copied from interface: CountConvertible
This method converts a register into a count. 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:
convertCount in interface CountConvertible
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
See Also:
CountConvertible.convertCount( de.dante.extex.interpreter.context.Context, de.dante.extex.interpreter.TokenSource, de.dante.extex.typesetter.Typesetter)

convertTokens

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

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
