Class FactorRegistry

java.lang.Object

com.quantfinlib.crb.FactorRegistry

public final class FactorRegistry
extends Object

Dense integer ids for risk-factor names — the SymbolRegistry pattern applied to the central risk book's factor space, so exposure arithmetic runs over primitive arrays while the factor names stay readable (EQ:AAPL, CCY:EUR, FXVEGA:EURUSD). Grow-only; ids are registration order. Research/warm lane.
