Class LockAnalysis

java.lang.Object

org.checkerframework.dataflow.analysis.AbstractAnalysis<V,S,T>

org.checkerframework.dataflow.analysis.ForwardAnalysisImpl<V,S,T>

org.checkerframework.framework.flow.CFAbstractAnalysis<CFValue,LockStore,LockTransfer>

org.checkerframework.checker.lock.LockAnalysis

All Implemented Interfaces:

Analysis<CFValue,LockStore,LockTransfer>, ForwardAnalysis<CFValue,LockStore,LockTransfer>

public class LockAnalysis
extends CFAbstractAnalysis<CFValue,LockStore,LockTransfer>

The analysis class for the lock type system.

This class extends CFAbstractAnalysis so that LockStore is used rather than CFStore.
