Detailed Description

Seekable byte stream for reading file contents.

Member Function Documentation

Close()

virtual Status iceberg::SeekableInputStream::Close ( )

pure virtual

Close the stream. Implementations should allow repeated Close calls.

Implemented in iceberg::test::StdSeekableInputStream.

Position()

virtual Result< int64_t > iceberg::SeekableInputStream::Position ( ) const

pure virtual

Return the current read position.

Implemented in iceberg::test::StdSeekableInputStream.

Read()

virtual Result< int64_t > iceberg::SeekableInputStream::Read ( std::span< std::byte >  out )

pure virtual

Read up to out.size() bytes from the current position.

Implemented in iceberg::test::StdSeekableInputStream.

ReadFully()

virtual Status iceberg::SeekableInputStream::ReadFully ( int64_t  position, std::span< std::byte >  out  )

pure virtual

Read exactly out.size() bytes from an absolute position.

Fails if fewer than out.size() bytes are available. The current stream position after this call is unspecified; callers should Seek before subsequent position-dependent reads.

Implemented in iceberg::test::StdSeekableInputStream.

Seek()

virtual Status iceberg::SeekableInputStream::Seek ( int64_t  position )

pure virtual

Seek to an absolute byte position.

Implemented in iceberg::test::StdSeekableInputStream.
