示例1: getEncodedSize
size_t MessageEncoder::getEncodedSize(const qpid::types::Variant::Map& map, bool alwaysUseLargeMap)
{
size_t total = getEncodedSizeForElements(map);
//its not just the count that determines whether we can use a small map, but the aggregate size:
if (alwaysUseLargeMap || map.size()*2 > 255 || total > 255) total += 4/*size*/ + 4/*count*/;
else total += 1/*size*/ + 1/*count*/;
total += 1 /*code for map itself*/;
return total;
}示例2: writeApplicationProperties
void MessageEncoder::writeApplicationProperties(const qpid::types::Variant::Map& properties)
{
writeApplicationProperties(properties, !optimise || properties.size()*2 > 255 || getEncodedSizeForElements(properties) > 255);
}示例3: writeMap
