Public Functions

virtual void handleWrite(const std::byte *data, uint64_t size) override

virtual void end() override: Called when the writer wants to close the current output Chunk. After this call, data() and size() should return the data and size of the compressed data.

virtual uint64_t size() const override: Returns the size in bytes of the uncompressed data.

virtual uint64_t compressedSize() const override: Returns the size in bytes of the compressed data. This will only be called after end().

virtual bool empty() const override: Returns true if write() has never been called since initialization or the last call to clear().

virtual void handleClear() override

virtual const std::byte *data() const override: Returns a pointer to the uncompressed data.

virtual const std::byte *compressedData() const override: Returns a pointer to the compressed data. This will only be called after end().
