C++ (Cpp) HasRule Examples

Example #1

void
FontFace::DisconnectFromRule()
{
  MOZ_ASSERT(HasRule());

  // Make a copy of the descriptors.
  mDescriptors = new CSSFontFaceDescriptors;
  mRule->GetDescriptors(*mDescriptors);
  mRule = nullptr;
  mInFontFaceSet = false;
}

Example #2

void
FontFace::GetDesc(nsCSSFontDesc aDescID, nsCSSValue& aResult) const
{
  if (HasRule()) {
    MOZ_ASSERT(mRule);
    MOZ_ASSERT(!mDescriptors);
    mRule->GetDesc(aDescID, aResult);
  } else {
    aResult = mDescriptors->Get(aDescID);
  }
}

Example #3

void
FontFace::SetDescriptor(nsCSSFontDesc aFontDesc,
                        const nsAString& aValue,
                        ErrorResult& aRv)
{
  NS_ASSERTION(!HasRule(),
               "we don't handle rule backed FontFace objects yet");
  if (HasRule()) {
    return;
  }

  nsCSSValue parsedValue;
  if (!ParseDescriptor(aFontDesc, aValue, parsedValue)) {
    aRv.Throw(NS_ERROR_DOM_SYNTAX_ERR);
    return;
  }

  mDescriptors->Get(aFontDesc) = parsedValue;

  // XXX Setting descriptors doesn't actually have any effect on FontFace
  // objects that have started loading or have already been loaded.
}
