class SeekTable

Defined at line 153 of file ../../src/lib/chunked-compression/chunked-archive.h

A parsed view of a chunked archive's seek table.

Constructed by parsing a buffer containing a raw archive (see |HeaderReader::Parse()|).

Public Methods

size_t CompressedSize ()

Returns the size of the compressed archive.

Equal to the end of the greatest frame (i.e. its offset + size).

Defined at line 18 of file ../../src/lib/chunked-compression/chunked-archive.cc

size_t SerializedHeaderSize ()

Returns the size of the serialized header (i.e. everything but the actual compressed frames).

Defined at line 32 of file ../../src/lib/chunked-compression/chunked-archive.cc

size_t DecompressedSize ()

Returns the expected size of the archive after decompression.

Equal to the end of the greatest frame (i.e. its offset + size).

Defined at line 36 of file ../../src/lib/chunked-compression/chunked-archive.cc

std::optional<size_t> EntryForCompressedOffset (size_t offset)

Lookup functions to find the entry in the seek table which covers |offset| in either the

compressed or decompressed space.

Returns the index into |SeekTable()| where the entry is stored, or std::nullopt if the

offset is not covered. (Note that there can be gaps in the *compressed* frames, but the

decompressed frames are contiguous).
