| /** | |
| * The {@code NumericShaper} class is used to convert Latin-1 (European) | |
| * digits to other Unicode decimal digits. Users of this class will | |
| * primarily be people who wish to present data using | |
| * national digit shapes, but find it more convenient to represent the | |
| * data internally using Latin-1 (European) digits. This does not | |
| * interpret the deprecated numeric shape selector character (U+206E). | |
| * <p> | |
| * Instances of {@code NumericShaper} are typically applied | |
| * as attributes to text with the | |
| * {@link TextAttribute#NUMERIC_SHAPING NUMERIC_SHAPING} attribute | |
| * of the {@code TextAttribute} class. | |
| * For example, this code snippet causes a {@code TextLayout} to | |
| * shape European digits to Arabic in an Arabic context:<br> | |
| * <blockquote><pre> | |
| * Map map = new HashMap(); | |
| * map.put(TextAttribute.NUMERIC_SHAPING, | |
| * NumericShaper.getContextualShaper(NumericShaper.ARABIC)); | |
| * FontRenderContext frc = ...; | |
| * TextLayout layout = new TextLayout(text, map, frc); | |
| * layout.draw(g2d, x, y); | |
| * </pre></blockquote> | |
| * <br> | |
| * It is also possible to perform numeric shaping explicitly using instances | |
| * of {@code NumericShaper}, as this code snippet demonstrates:<br> | |
| * <blockquote><pre> | |
| * char[] text = ...; | |
| * // shape all EUROPEAN digits (except zero) to ARABIC digits | |
| * NumericShaper shaper = NumericShaper.getShaper(NumericShaper.ARABIC); | |
| * shaper.shape(text, start, count); | |
| * | |
| * // shape European digits to ARABIC digits if preceding text is Arabic, or | |
| * // shape European digits to TAMIL digits if preceding text is Tamil, or | |
| * // leave European digits alone if there is no preceding text, or | |
| * // preceding text is neither Arabic nor Tamil | |
| * NumericShaper shaper = | |
| * NumericShaper.getContextualShaper(NumericShaper.ARABIC | | |
| * NumericShaper.TAMIL, | |
| * NumericShaper.EUROPEAN); | |
| * shaper.shape(text, start, count); | |
| * </pre></blockquote> | |
| * | |
| * <p><b>Bit mask- and enum-based Unicode ranges</b></p> | |
| * | |
| * <p>This class supports two different programming interfaces to | |
| * represent Unicode ranges for script-specific digits: bit | |
| * mask-based ones, such as {@link #ARABIC NumericShaper.ARABIC}, and | |
| * enum-based ones, such as {@link NumericShaper.Range#ARABIC}. | |
| * Multiple ranges can be specified by ORing bit mask-based constants, | |
| * such as: | |
| * <blockquote><pre> | |
| * NumericShaper.ARABIC | NumericShaper.TAMIL | |
| * </pre></blockquote> | |
| * or creating a {@code Set} with the {@link NumericShaper.Range} | |
| * constants, such as: | |
| * <blockquote><pre> | |
| * EnumSet.of(NumericShaper.Range.ARABIC, NumericShaper.Range.TAMIL) | |
| * </pre></blockquote> | |
| * The enum-based ranges are a super set of the bit mask-based ones. | |
| * | |
| * <p>If the two interfaces are mixed (including serialization), | |
| * Unicode range values are mapped to their counterparts where such | |
| * mapping is possible, such as {@code NumericShaper.Range.ARABIC} | |
| * from/to {@code NumericShaper.ARABIC}. If any unmappable range | |
| * values are specified, such as {@code NumericShaper.Range.BALINESE}, | |
| * those ranges are ignored. | |
| * | |
| * <p><b>Decimal Digits Precedence</b></p> | |
| * | |
| * <p>A Unicode range may have more than one set of decimal digits. If | |
| * multiple decimal digits sets are specified for the same Unicode | |
| * range, one of the sets will take precedence as follows. | |
| * | |
| * <table class="plain"> | |
| * <caption>NumericShaper constants precedence</caption> | |
