示例1: peek
size_t SkMemoryStream::peek(void* buffer, size_t size) const {
SkASSERT(buffer != nullptr);
const size_t currentOffset = fOffset;
SkMemoryStream* nonConstThis = const_cast<SkMemoryStream*>(this);
const size_t bytesRead = nonConstThis->read(buffer, size);
nonConstThis->fOffset = currentOffset;
return bytesRead;
}示例2: peek
bool SkMemoryStream::peek(void* buffer, size_t size) const {
SkASSERT(buffer != nullptr);
const size_t position = fOffset;
if (size > fData->size() - position) {
// The stream is not large enough to satisfy this request.
return false;
}
SkMemoryStream* nonConstThis = const_cast<SkMemoryStream*>(this);
SkDEBUGCODE(const size_t bytesRead =) nonConstThis->read(buffer, size);
SkASSERT(bytesRead == size);
nonConstThis->fOffset = position;
return true;
