示例1: test_initial_offset
// Test using a stream with an initial offset.
static void test_initial_offset(skiatest::Reporter* reporter, size_t bufferSize) {
SkMemoryStream* memStream = new SkMemoryStream(gAbcs, strlen(gAbcs), false);
// Skip a few characters into the memStream, so that bufferedStream represents an offset into
// the stream it wraps.
const size_t arbitraryOffset = 17;
memStream->skip(arbitraryOffset);
std::unique_ptr<SkStream> bufferedStream(SkFrontBufferedStream::Create(memStream, bufferSize));
// Since SkMemoryStream has a length, bufferedStream must also.
REPORTER_ASSERT(reporter, bufferedStream->hasLength());
const size_t amountToRead = 10;
const size_t bufferedLength = bufferedStream->getLength();
size_t currentPosition = 0;
// Read the stream in chunks. After each read, the position must match currentPosition,
// which sums the amount attempted to read, unless the end of the stream has been reached.
// Importantly, the end should not have been reached until currentPosition == bufferedLength.
while (currentPosition < bufferedLength) {
REPORTER_ASSERT(reporter, !bufferedStream->isAtEnd());
test_read(reporter, bufferedStream.get(), gAbcs + arbitraryOffset + currentPosition,
amountToRead);
currentPosition = SkTMin(currentPosition + amountToRead, bufferedLength);
REPORTER_ASSERT(reporter, memStream->getPosition() - arbitraryOffset == currentPosition);
}
REPORTER_ASSERT(reporter, bufferedStream->isAtEnd());
REPORTER_ASSERT(reporter, bufferedLength == currentPosition);
}
