示例1: Block
bool
Block::fromBuffer(const ConstBufferPtr& wire, size_t offset, Block& block)
{
Buffer::const_iterator tempBegin = wire->begin() + offset;
uint32_t type;
bool isOk = Tlv::readType(tempBegin, wire->end(), type);
if (!isOk)
return false;
uint64_t length;
isOk = Tlv::readVarNumber(tempBegin, wire->end(), length);
if (!isOk)
return false;
if (length > static_cast<uint64_t>(wire->end() - tempBegin))
{
return false;
}
block = Block(wire, type,
wire->begin() + offset, tempBegin + length,
tempBegin, tempBegin + length);
return true;
