handleUnsafeOperation()

virtual void clang::UnsafeBufferUsageHandler::handleUnsafeOperation ( const Stmt *  Operation, bool  IsRelatedToDecl  )

pure virtual

Invoked when an unsafe operation over raw pointers is found.

Referenced by clang::checkUnsafeBufferUsage().

handleUnsafeVariableGroup()

virtual void clang::UnsafeBufferUsageHandler::handleUnsafeVariableGroup ( const VarDecl *  Variable, const DefMapTy &  VarGrpMap, FixItList &&  Fixes  )

pure virtual

Invoked when a fix is suggested against a variable.

This function groups all variables that must be fixed together (i.e their types must be changed to the same target type to prevent type mismatches) into a single fixit.

isSafeBufferOptOut()

virtual bool clang::UnsafeBufferUsageHandler::isSafeBufferOptOut ( const SourceLocation &  Loc ) const

pure virtual

Returns a reference to the Preprocessor:
