Class CentralityState

java.lang.Object
jadx.core.dex.visitors.finaly.CentralityState
public final class CentralityState extends Object
A centrality state is an object which helps track how instructions can be skipped. When looking for a finally, one of the things we have to do is make sure that instructions are not part of the return and are actually part of the "finally" block. This object helps keep track of registers, instructions etc to see if instructions can be skipped.
