A file abstraction for randomly reading the contents of a file.
tensorflow::RandomAccessFile::RandomAccessFile()virtual tensorflow::RandomAccessFile::~RandomAccessFile()virtual Status tensorflow::RandomAccessFile::Read(uint64 offset, size_t n, StringPiece *result, char *scratch) const =0- Reads up to "n" bytes from the file starting at "offset".
virtual Status tensorflow::RandomAccessFile::Read(uint64 offset, size_t n, StringPiece *result, char *scratch) const =0
Reads up to "n" bytes from the file starting at "offset".
"scratch[0..n-1]" may be written by this routine. Sets "*result" to the data that was read (including if fewer than "n" bytes were successfully read). May set "*result" to point at data in "scratch[0..n-1]", so "scratch[0..n-1]" must be live when "*result" is used.
On OK returned status: "n" bytes have been stored in "*result". On non-OK returned status: [0..n] bytes have been stored in "*result".
Returns OUT_OF_RANGE if fewer than n bytes were stored in "*result" because of EOF.
Safe for concurrent use by multiple threads.
