	Write the low bits of value starting at absolute bit offset bitOffset, overwriting whatever was there.

Detailed Description

A little-endian bit writer over a record buffer — the encode counterpart of BitReader.

write() OVERWRITES (sets and clears each bit), so it works on a zeroed buffer (canonical encode) and for patching an existing record in place alike.

Constructor & Destructor Documentation

BitWriter()

wowlib::db::wdc::BitWriter::BitWriter ( std::byte * base, std::size_t limit )

inline

Parameters

base	the record's first byte.
limit	bytes available from base (bounds guard).

Definition at line 63 of file bit_stream.hpp.

Member Function Documentation

write()

void wowlib::db::wdc::BitWriter::write ( std::size_t bitOffset, std::size_t bits, std::uint64_t value )

inline

Write the low bits of value starting at absolute bit offset bitOffset, overwriting whatever was there.

Bits that would overrun the buffer are dropped.

Parameters

bitOffset	the starting bit position within the record.
bits	the field width in bits (<= 64).
value	the value whose low bits are written.
