can anyone give me a hint on "lhs" and "rhs"

[Allen Zhang]

Hello all,
can anyone give me a hint on "lhs" and "rhs" in Resource.java file
what are they short for?


Thanks,
Allen


for example:


public static Resource addTo(Resource lhs, Resource rhs) {
  lhs.setMemory(lhs.getMemory() + rhs.getMemory());
lhs.setVirtualCores(lhs.getVirtualCores() + rhs.getVirtualCores());
return lhs;
}
