ReportI was recently engaged in a bug where the size of container caused problems. The solution we arrived at was to implement compression of the container. The solution is trivial; but the APIs to get there took me a while to discover, and as I couldn't find any other post on this, I'm sharing it.
How to implement compression/decompression of pack/unpack methods using BinData and ContainerClass.
public container pack()
{
// Business as usual...
container result = [#currentVersion, #currentList];
// Compress
ContainerClass containerClass = new ContainerClass(result);
binData = new BinData();
binData.setData(containerClass.toBlob());
binData.compressLZ77(12);
return binData.getData();
}
public boolean unpack(container _compressed)
{
// Decompress
BinData binData = new BinData();
binData.setData(_compressed);
binData.decompressLZ77();
container packed = ContainerClass::blob2Container(binData.getData());
// Business as usual...
Version version = RunBase::getVersion(packed);
switch (version)
{
case #CurrentVersion:
[version, #currentList] = packed;
break;
default:
return false;
}
return true;
}
