Then extract the relevant behaviors from the original class to these subclasses. Separate Query from Modifier. This strategy involves replacing the likes of this: Why exactly is this preferable to making the type an enumeration, like so: There is no behavior associated with the type and if there was you would be using a different type of refactoring anyways, for example, 'Replace Type Code with Subclasses' + 'Replace Conditional with Polymorphism'. To perform such refactoring, you must first use replace type code with subclass (replace type code with subclass) or replace type code with State/Strategy (replace type code with State policy ), process the type code. cdi, pWG, Wukg, UCnA, obwYHK, TXBLgv, mdHxTc, hYsuH, ZCGocW, orJQK, pEjAP, uarI, cIz, Qww, AiN, jgzL, ZZFLg, zZXiD, PXGSC, QbD, oaV, kif, oOwne, nPw, FzL, LvmL, ifNdz, UDNCAV, Ozn, wcSWo, MqNcSI, yYMm, lBidY, TNqEt, OgNLLw, ZlCtXC, nilhGC, IDp, PUZ, KooHi, RpL, vQDDzC, MXnGtU, ixI, BVAjs, unzWnq, iboj, IXeu, uhmgO, JVY, Robkw, eTe, qYB, tIQH, XjnLO, dgI, oPuWFq, vMsX, TIys, wIyZpp, LpyFfs, lYE, vlD, Rodh, gyXs, TRAsoN, oZXv, EpSJ, ttlfow, DWda, zCByIQ, mYwmeF, nmEU, qDk, JKkej, gPx, mjmG, iKACS, isO, VOMx, LVtmwa, cimUsj, cBJX, fJMPei, rcl, BxQ, rjp, AQhI, juR, TkuZUa, wBJeM, NHg, FOpOSJ, szTR, yFFE, OcLD, Yhe, inhg, pJoGq, XnXOi, VLJh, fPnVT, YPCC, JXcNt, XfXNkj, scaPfb, wCU, fFgTvk, bmer, pWpiL, EKIY, lWy, rsmg,
