Class Summary

Class	Description
DerefFinder
IsNullConditionDecision	A control decision which resulted in information being gained about whether a particular value is null or non-null on the IFCMP_EDGE and FALL_THROUGH_EDGE branches.
IsNullValue	A class to abstractly represent values in stack slots, indicating whether thoses values can be null, non-null, null on some incoming path, or unknown.
IsNullValueAnalysis	A dataflow analysis to detect potential null pointer dereferences.

NonNullSpecification
NullDerefAndRedundantComparisonFinder	A user-friendly front end for finding null pointer dereferences and redundant null comparisions.
NullValueUnconditionalDeref	Collected information about a single value number observed at one or more locations to be both definitely-null and unconditionally dereferenced.
ParameterNullnessPropertyDatabase	Method property database storing which method parameters might be unconditionally dereferenced.
PointerUsageRequiringNonNullValue
RedundantBranch	An instruction recorded as a redundant reference comparison.
ReturnPathType	A dataflow value that indicates what kind of return path is possible at the current program location.
ReturnPathTypeAnalysis	A dataflow analysis to determine, at each location in a method's CFG, whether or not it is possible to return normally at that location.
ReturnPathTypeDataflow	Dataflow class for ReturnPathTypeAnalysis.
ReturnValueNullnessPropertyDatabase	Method property database storing which methods return values guaranteed to be nonnull
