Public Member Functions
~WritableBinaryStream () override=default
virtual Error writeBytes (uint64_t Offset, ArrayRef< uint8_t > Data)=0
Attempt to write the given bytes into the stream at the desired offset.
virtual Error commit ()=0
For buffered streams, commits changes to the backing store.
BinaryStreamFlags getFlags () const override
Return the properties of this stream.

virtual Error readBytes (uint64_t Offset, uint64_t Size, ArrayRef< uint8_t > &Buffer)=0
Given an offset into the stream and a number of bytes, attempt to read the bytes and set the output ArrayRef to point to data owned by the stream.
virtual Error readLongestContiguousChunk (uint64_t Offset, ArrayRef< uint8_t > &Buffer)=0
Given an offset into the stream, read as much as possible without copying any data.
virtual uint64_t getLength ()=0
Return the number of bytes of data in this stream.

A BinaryStream which can be read from as well as written to.

Note that writing to a BinaryStream always necessitates copying from the input buffer to the stream's backing store. Streams are assumed to be buffered so that to be portable it is necessary to call commit() on the stream when all data has been written.
