Class XtfLookupList

java.lang.Object
  org.extex.font.format.xtf.tables.gps.XtfLookupList

All Implemented Interfaces:

XMLWriterConvertible

public class XtfLookupList
extends java.lang.Object
implements XMLWriterConvertible

List for all LookupTables.

lookup list table

The headers of the GSUB and GPOS tables contain offsets to Lookup List tables (LookupList) for glyph substitution (GSUB table) and glyph positioning (GPOS table). The LookupList table contains an array of offsets to Lookup tables (Lookup). The font developer defines the Lookup sequence in the Lookup array to control the order in which a text-processing client applies lookup data to glyph substitution and positioning operations. LookupCount specifies the total number of Lookup table offsets in the array.

Type	Name	Description
uint16	LookupCount	Number of lookups in this table
Offset	Lookup[LookupCount]	Array of offsets to Lookup tables-from beginning of LookupList -zero based (first lookup is Lookup index = 0)
