Class LockChecker

public class LockChecker extends Object

Front-end for LockDataflow that can avoid doing unnecessary work (e.g., actually performing the lock dataflow) if the method analyzed does not contain explicit monitorenter/monitorexit instructions.

Note that because LockSets use value numbers, ValueNumberAnalysis must be performed for all methods that are synchronized or contain explicit monitorenter/monitorexit instructions.
