Public Member Functions | |
| ChromiumCheckModel ()=default | |
| bool | transfer (const CFGElement &Element, Environment &Env) override |
Return value indicates whether the model processed the Element. | |
| virtual bool | transfer (const CFGElement &Element, Environment &Env)=0 |
Return value indicates whether the model processed the Element. | |
 Public Member Functions inherited from clang::dataflow::Environment::ValueModel | |
| virtual | ~ValueModel ()=default |
| virtual ComparisonResult | compare (QualType Type, const Value &Val1, const Environment &Env1, const Value &Val2, const Environment &Env2) |
Returns: Same: Val1 is equivalent to Val2, according to the model. | |
| virtual bool | merge (QualType Type, const Value &Val1, const Environment &Env1, const Value &Val2, const Environment &Env2, Value &MergedVal, Environment &MergedEnv) |
Modifies MergedVal to approximate both Val1 and Val2. | |
| virtual Value * | widen (QualType Type, Value &Prev, const Environment &PrevEnv, Value &Current, Environment &CurrentEnv) |
| This function may widen the current value – replace it with an approximation that can reach a fixed point more quickly than iterated application of the transfer function alone. | |
