Examples with CodePointIterator sun.text.CodePointIterator used on opensource projects

Example 1 with CodePointIterator

use of sun.text.CodePointIterator in project jdk8u_jdk by JetBrains.

the class StyledParagraph method addFonts.

/**
     * Resolve the given chars into Fonts using FontResolver, then add
     * font runs for each.
     */
private void addFonts(char[] chars, Map<? extends Attribute, ?> attributes, int start, int limit) {
    FontResolver resolver = FontResolver.getInstance();
    CodePointIterator iter = CodePointIterator.create(chars, start, limit);
    for (int runStart = iter.charIndex(); runStart < limit; runStart = iter.charIndex()) {
        int fontIndex = resolver.nextFontRunIndex(iter);
        addFont(resolver.getFont(fontIndex, attributes), runStart);
    }
}

Example 2 with CodePointIterator

use of sun.text.CodePointIterator in project jdk8u_jdk by JetBrains.

the class TextLayout method singleFont.

/*
     * Determines a font for the attributes, and if a single font can render
     * all the text on one baseline, return it, otherwise null.  If the
     * attributes specify a font, assume it can display all the text without
     * checking.
     * If the AttributeSet contains an embedded graphic, return null.
     */
