Implementation of dataflow analysis for checking whether
obligations to close streams and other resources (e.g.

| IsNullValueFrame |
| Class and Description |
|---|
| 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.
|
| 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.
