Classes in edu.umd.cs.findbugs.ba.npe used by edu.umd.cs.findbugs.ba.npe

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.

IsNullValueAnalysis.PointerEqualityCheck

IsNullValueAnalysisFeatures
Knobs for null value analysis.

IsNullValueFrame

LocationWhereValueBecomesNull
A Location where a particular value number becomes null.

NullDerefAndRedundantComparisonCollector
Callback interface for collecting null pointer derefs and redundant null comparisons.

NullValueUnconditionalDeref
Collected information about a single value number observed at one or more locations to be both definitely-null and unconditionally dereferenced.

ParameterNullnessProperty
Method property recording which parameters are (or should be) non-null, meaning that null values should not be passed as their arguments.

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.
