public class Glueshrinkorder

extends AbstractCode

implements CountConvertible, DimenConvertible, Theable

This class provides an implementation for the primitive \glueshrinkorder.

The Primitive \glueshrinkorder

The primitive \glueshrinkorder determines the order of the glue shrink component of the following glue specification. A fixed, non-shrinkable glue returns the value 0. Glue with the order fil gives 1, fill gives 2, and filll gives 3.

Note that the glue specification of 1 fi returns also 1. This is due to the compatibility with eTeX which does not have this unit. This unit has been introduced by Omega.

Syntax

    ⟨glueshrinkorder⟩
      → \glueshrinkorder ⟨glue⟩

Glueshrinkorder

public Glueshrinkorder(java.lang.String name)

Creates a new object.

Parameters:

name - the name for debugging

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)

convertDimen

public long convertDimen(Context context,
                         TokenSource source,
                         Typesetter typesetter)
                  throws InterpreterException

Description copied from interface: DimenConvertible

This method converts a register into a dimen. 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. The return value is the length in scaled points.

Specified by:

convertDimen in interface DimenConvertible

Parameters:

context - the interpreter context

source - the source for new tokens

typesetter - the typesetter to use for conversion

Returns:

the converted value in sp

Throws:

InterpreterException - in case of an error

DimenConvertible.convertDimen( 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
