/**
 *  This class represents BidiFlag objects and provides initial values for
 *  all flag options.
 *  

* Bidi text can be stored in different formats, which are characterized * by 5 Bidi attributes, whose values may be stored in 5 Bidi flags. * These 5 flags constitute a BidiFlagSet. *

* A BidiFlagSet object contains a value for each of the 5 Bidi flags * which represent the Bidi attributes. The 5 attributes are: *

    *
  • type of text (Implicit or Visual) *
  • orientation (LTR, RTL, Contextual LTR, Contextual RTL) *
  • symmetric swapping (Yes or No) *
  • numeral shapes (Nominal, National or Contextual) *
  • text shapes (Nominal, Shaped, Initial, Middle, Final or Isolated) *
* The BidiFlags are pre-defined in this class. Each one represents one * possible value of one Bidi attribute. All possible values are defined, * so there is no need (or possibility) to add new ones. * *

Multi-threading considerations: There are no multi-threading * concerns for this class, since it only defines static * final instances. * */ public class BidiFlag { /** * Value identifying Implicit type of text */ public static final BidiFlag TYPE_IMPLICIT = new BidiFlag(BidiFlagSet.ITYPE_IMPLICIT, BidiFlagSet.TYPE_MASK); /** * Value identifying Visual type of text */ public static final BidiFlag TYPE_VISUAL = new BidiFlag(BidiFlagSet.ITYPE_VISUAL, BidiFlagSet.TYPE_MASK); /** * Value identifying LTR orientation */ public static final BidiFlag ORIENTATION_LTR = new BidiFlag(BidiFlagSet.IORIENTATION_LTR, BidiFlagSet.ORIENTATION_MASK); /** * Value identifying RTL orientation */ public static final BidiFlag ORIENTATION_RTL = new BidiFlag(BidiFlagSet.IORIENTATION_RTL, BidiFlagSet.ORIENTATION_MASK); /** * Value identifying Contextual orientation with default to LTR */ public static final BidiFlag ORIENTATION_CONTEXT_LTR = new BidiFlag(BidiFlagSet.IORIENTATION_CONTEXT_LTR, BidiFlagSet.ORIENTATION_MASK); /** * Value identifying Contextual orientation with default to RTL */ public static final BidiFlag ORIENTATION_CONTEXT_RTL = new BidiFlag(BidiFlagSet.IORIENTATION_CONTEXT_RTL, BidiFlagSet.ORIENTATION_MASK); /** * Value identifying that symmetric swapping has been applied */ public static final BidiFlag SWAP_YES = new BidiFlag(BidiFlagSet.ISWAP_YES, BidiFlagSet.SWAP_MASK); /** * Value identifying that symmetric swapping has not been applied */ public static final BidiFlag SWAP_NO = new BidiFlag(BidiFlagSet.ISWAP_NO, BidiFlagSet.SWAP_MASK); /** * Value identifying that numeral shapes are Nominal */ public static final BidiFlag NUMERALS_NOMINAL = new BidiFlag(BidiFlagSet.INUMERALS_NOMINAL, BidiFlagSet.NUMERALS_MASK); /** * Value identifying that numeral shapes are National */ public static final BidiFlag NUMERALS_NATIONAL = new BidiFlag(BidiFlagSet.INUMERALS_NATIONAL, BidiFlagSet.NUMERALS_MASK); /** * Value identifying that numeral shapes are Contextual (Nominal or National * depending on context) */ public static final BidiFlag NUMERALS_CONTEXTUAL = new BidiFlag(BidiFlagSet.INUMERALS_CONTEXTUAL, BidiFlagSet.NUMERALS_MASK); /** * Value identifying that numeral shapes may be Nominal or National */ public static final BidiFlag NUMERALS_ANY = new BidiFlag(BidiFlagSet.INUMERALS_ANY, BidiFlagSet.NUMERALS_MASK); /** * Value identifying that the text is stored in Nominal characters */ public static final BidiFlag TEXT_NOMINAL = new BidiFlag(BidiFlagSet.ITEXT_NOMINAL, BidiFlagSet.TEXT_MASK); /** * Value identifying that the text is stored in Shaped characters */ public static final BidiFlag TEXT_SHAPED = new BidiFlag(BidiFlagSet.ITEXT_SHAPED, BidiFlagSet.TEXT_MASK); /** * Value identifying that the text must be displayed in Initial characters */ public static final BidiFlag TEXT_INITIAL = new BidiFlag(BidiFlagSet.ITEXT_INITIAL, BidiFlagSet.TEXT_MASK); /** * Value identifying that the text must be displayed in Middle characters */ public static final BidiFlag TEXT_MIDDLE = new BidiFlag(BidiFlagSet.ITEXT_MIDDLE, BidiFlagSet.TEXT_MASK); /** * Value identifying that the text must be displayed in Final characters */ public static final BidiFlag TEXT_FINAL = new BidiFlag(BidiFlagSet.ITEXT_FINAL, BidiFlagSet.TEXT_MASK); /** * Value identifying that the text must be displayed in Isolated characters */ public static final BidiFlag TEXT_ISOLATED = new BidiFlag(BidiFlagSet.ITEXT_ISOLATED, BidiFlagSet.TEXT_MASK); int value; int mask; // This makes BidiFlagSet.setOneFlag more efficient private BidiFlag(int initValue, int initMask) { value = initValue; mask = initMask; } }
