Method Detail

getMyLocalizer

protected static Localizer getMyLocalizer()

Getter for the localizer. The localizer is associated with the name of the class GlueComponent.

Returns:

the localizer

parse

public static GlueComponent parse(Context context,
                                  TokenSource source,
                                  Typesetter typesetter,
                                  boolean fixed)

                                  TypesetterException

Creates a new object.

Parameters:

context - the interpreter context

source - the source for the tokens to be read

typesetter - the typesetter

fixed - if true then no glue order is allowed

Returns:

a new instance with the value from the input stream

Throws:

HelpingException - in case of an error

TypesetterException - in case of an error in the typesetter

attachUnit

public static GlueComponent attachUnit(long value,
                                       Context context,
                                       TokenSource source,
                                       Typesetter typesetter,
                                       boolean fixed)
                                throws HelpingException,
                                       TypesetterException

Convert a value by scanning a unit and storing its converted value in a GlueComponent.

Parameters:

context - the interpreter context

source - the source for the tokens to be read

typesetter - the typesetter

fixed - if true then no glue order is allowed

value - the value to encapsulate

Returns:

the value converted into a GlueComponent or null if no suitable unit could be found

Throws:

HelpingException - in case of an error

TypesetterException - in case of an error in the typesetter

parse

public static GlueComponent parse(TokenSource source,
                                  Context context,
                                  Typesetter typesetter)
                           throws HelpingException,
                                  TypesetterException

Creates a new object from a TokenStream.

Parameters:

source - the source for new tokens

context - the interpreter context

typesetter - the typesetter

Returns:

a new instance with the value from the input stream

Throws:

HelpingException - in case of an error

TypesetterException - in case of an error in the typesetter
