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.
