      org.extex.unit.omega.register.Ogluestretchorder

All Implemented Interfaces:

java.io.Serializable, CountConvertible, Code, Theable

public class Ogluestretchorder
extends AbstractCode
implements CountConvertible, Theable

This class provides an implementation for the primitive \gluestretchorder.

The Primitive \gluestretchorder

The primitive \gluestretchorder determines the order of the glue stretch component of the following glue specification. A fixed, non-stretchable glue returns the value 0. Glue with the order fi gives 1, fil gives 2, fill gives 3, and filll gives 4.

Note that the glue specification of 1 fi has been introduced by Omega.

Syntax

The formal description of this primitive is the following:

    ⟨gluestretchorder⟩
      → \gluestretchorder ⟨glue⟩ 

Examples

   \gluestretchorder\skip1

Method Detail

convertCount

public long convertCount(Context context,
                         TokenSource source,
                         Typesetter typesetter)
                  throws HelpingException,
                         TypesetterException

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:

HelpingException - in case of an error

TypesetterException - in case of an error in the typesetter

public Tokens the(Context context,
                  TokenSource source,

           throws CatcodeException,
                  HelpingException,
                  TypesetterException

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:

CatcodeException - in case of an error in token creation

ConfigurationException - in case of an configuration error

HelpingException - in case of an error

TypesetterException - in case of an error
