BgzfBlock

Structure representing BGZF block. In general, users shouldn't use it, as it is EXTREMELY low-level.

struct BgzfBlock {

ulong start_offset;

ulong end_offset();

ushort bsize;

ushort cdata_size;

ubyte[] _buffer;

inout(ubyte[]) compressed_data();

uint input_size;

hash_t toHash();

bool opEquals(BgzfBlock other);

int opCmp(BgzfBlock other);

}

Members

Functions

compressed_data inout(ubyte[]) compressed_data(): If block has been already decompressed, result is undefined.
end_offset ulong end_offset(): end offset in the file, in bytes
opCmp int opCmp(BgzfBlock other): Undocumented in source. Be warned that the author may not have intended to support it.
opEquals bool opEquals(BgzfBlock other): Undocumented in source. Be warned that the author may not have intended to support it.
toHash hash_t toHash(): Undocumented in source. Be warned that the author may not have intended to support it.

Variables

_buffer ubyte[] _buffer;: A buffer is used to reduce number of allocations.
bsize ushort bsize;: total Block SIZE minus one
cdata_size ushort cdata_size;: compressed data size
crc32 uint crc32;: Undocumented in source.
dirty bool dirty;: Undocumented in source.
input_size uint input_size;: size of uncompressed data
start_offset ulong start_offset;: start offset in the file, in bytes
