Method Detail

getMemoryLocation

public JvmMemoryLocation getMemoryLocation()

copy

public BamLocationDependentJvmMemoryLocation<AbstractStateT> copy()

extractFirstValue

public <T extends LatticeAbstractState<T>> T extractFirstValue(T defaultValue)

Extract the value from the first state from the reached state corresponding to the program, memory location, and BAM cache entry represented by this object.

Most analyses will have one state at most for each program location, and this method should be mostly used for this kind of analyses since it will return the only valid state. It's also possible that, for analyses where multiple states are possible, the returned value might be non-deterministic depending on the underlying reached set implementation.

Returns:

an empty optional if there is no analysis state in the cache entry and program location represented by this object. Otherwise, the content for the memory location specified by this object of the first state (there is usually only one state anyway, but this is analysis-dependent) for that program location.
