C++ (Cpp) BidiResolver::determineParagraphDirectionality Examples

Example #1

File: BidiResolverTest.cpp Project: endlessm/chromium-browser

TextDirection determineParagraphDirectionality(const TextRun& textRun, bool* hasStrongDirectionality = 0)
{
    BidiResolver<TextRunIterator, BidiCharacterRun> resolver;
    resolver.setStatus(BidiStatus(LTR, false));
    resolver.setPositionIgnoringNestedIsolates(TextRunIterator(&textRun, 0));
    return resolver.determineParagraphDirectionality(hasStrongDirectionality);
}

Example #2

File: BidiTextRun.cpp Project: Jamesducque/mojo

TextDirection directionForRun(TextRun& run, bool& hasStrongDirectionality)
{
    BidiResolver<TextRunIterator, BidiCharacterRun> bidiResolver;
    bidiResolver.setStatus(BidiStatus(run.direction(), run.directionalOverride()));
    bidiResolver.setPositionIgnoringNestedIsolates(TextRunIterator(&run, 0));
    return bidiResolver.determineParagraphDirectionality(&hasStrongDirectionality);
}

Example #3

File: VTTCue.cpp Project: kjthegod/WebKit

// Almost the same as determineDirectionality in core/html/HTMLElement.cpp, but
// that one uses a "plain" TextRunIterator (which only checks for '\n').
static TextDirection determineDirectionality(const String& value, bool& hasStrongDirectionality)
{
    TextRun run(value);
    BidiResolver<VTTTextRunIterator, BidiCharacterRun> bidiResolver;
    bidiResolver.setStatus(BidiStatus(LTR, false));
    bidiResolver.setPositionIgnoringNestedIsolates(VTTTextRunIterator(&run, 0));
    return bidiResolver.determineParagraphDirectionality(&hasStrongDirectionality);
}

Example #4

File: BidiResolverTest.cpp Project: endlessm/chromium-browser

TEST(BidiResolver, Basic)
{
    bool hasStrongDirectionality;
    String value("foo");
    TextRun run(value);
    BidiResolver<TextRunIterator, BidiCharacterRun> bidiResolver;
    bidiResolver.setStatus(BidiStatus(run.direction(), run.directionalOverride()));
    bidiResolver.setPositionIgnoringNestedIsolates(TextRunIterator(&run, 0));
    TextDirection direction = bidiResolver.determineParagraphDirectionality(&hasStrongDirectionality);
    EXPECT_TRUE(hasStrongDirectionality);
    EXPECT_EQ(LTR, direction);
}

Example #5

File: BidiTextRun.cpp Project: kingysu/blink-crosswalk

TextDirection directionForRun(TextRun& run, bool* hasStrongDirectionality)
{
    if (!hasStrongDirectionality) {
        // 8bit is Latin-1 and therefore is always LTR.
        if (run.is8Bit())
            return LTR;

        // length == 1 for more than 90% of cases of width() for CJK text.
        if (run.length() == 1 && U16_IS_SINGLE(run.characters16()[0]))
            return directionForCharacter(run.characters16()[0]);
    }

    BidiResolver<TextRunIterator, BidiCharacterRun> bidiResolver;
    bidiResolver.setStatus(BidiStatus(run.direction(), run.directionalOverride()));
    bidiResolver.setPositionIgnoringNestedIsolates(TextRunIterator(&run, 0));
    return bidiResolver.determineParagraphDirectionality(hasStrongDirectionality);
