示例1: LengthRemaining
NS_IMETHODIMP
nsStringInputStream::ReadSegments(nsWriteSegmentFun aWriter, void* aClosure,
uint32_t aCount, uint32_t* aResult)
{
NS_ASSERTION(aResult, "null ptr");
NS_ASSERTION(Length() >= mOffset, "bad stream state");
if (Closed()) {
return NS_BASE_STREAM_CLOSED;
}
// We may be at end-of-file
uint32_t maxCount = LengthRemaining();
if (maxCount == 0) {
*aResult = 0;
return NS_OK;
}
if (aCount > maxCount) {
aCount = maxCount;
}
nsresult rv = aWriter(this, aClosure, mData.BeginReading() + mOffset, 0,
aCount, aResult);
if (NS_SUCCEEDED(rv)) {
NS_ASSERTION(*aResult <= aCount,
"writer should not write more than we asked it to write");
mOffset += *aResult;
}
// errors returned from the writer end here!
return NS_OK;
}示例2: tokenStart
/* static */
bool
MatchAutoCompleteFunction::findBeginning(const nsDependentCSubstring &aToken,
const nsACString &aSourceString)
{
NS_PRECONDITION(!aToken.IsEmpty(), "Don't search for an empty token!");
// We can't use StringBeginsWith here, unfortunately. Although it will
// happily take a case-insensitive UTF8 comparator, it eventually calls
// nsACString::Equals, which checks that the two strings contain the same
// number of bytes before calling the comparator. This is clearly not what
// we want.
const_char_iterator tokenStart(aToken.BeginReading()),
tokenEnd(aToken.EndReading()),
sourceStart(aSourceString.BeginReading()),
sourceEnd(aSourceString.EndReading());
PRBool dummy;
while (sourceStart < sourceEnd &&
CaseInsensitiveUTF8CharsEqual(sourceStart, tokenStart,
sourceEnd, tokenEnd,
&sourceStart, &tokenStart, &dummy)) {
// We found the token!
if (tokenStart >= tokenEnd) {
return true;
}
}
// We don't need to check CaseInsensitiveUTF8CharsEqual's error condition
// (stored in |dummy|), since the function will return false if it
// encounters an error.
return false;
}示例3:
static void
AppendPrefixToMap(PrefixStringMap& prefixes, nsDependentCSubstring& prefix)
{
if (!prefix.Length()) {
return;
}
nsCString* prefixString = prefixes.LookupOrAdd(prefix.Length());
prefixString->Append(prefix.BeginReading(), prefix.Length());
