Class SymbolRegistry

java.lang.Object
com.quantfinlib.marketdata.SymbolRegistry
public final class SymbolRegistry extends Object
Interns instrument symbols to dense int ids so the hot path never touches String hashing or map lookups: resolve the id once at subscription time, then publish and dispatch with primitive ints only.
