static bool AttrFilter(const ObjCMethodDecl *M)

Holds long-lived AST nodes (such as types and decls) that can be referred to throughout the semantic ...

AnalysisDeclContext contains the context data for the function, method or block under analysis.

bool getCheckerBooleanOption(StringRef CheckerName, StringRef OptionName, bool SearchInParents=false) const

Interprets an option's string value as a boolean.

A builtin binary operation expression such as "x + y" or "x <= y".

static bool isAssignmentOp(Opcode Opc)

ConstStmtVisitor - This class implements a simple visitor for Stmt subclasses.

Decl - This represents one declaration (or definition), e.g.

llvm::iterator_range< specific_attr_iterator< T > > specific_attrs() const

Expr * IgnoreParenCasts() LLVM_READONLY

Skip past any parentheses and casts which might surround this expression until reaching a fixed point...

One of these records is kept for each identifier that is lexed.

IdentifierInfo * getIdentifier() const

Get the identifier that names this declaration, if there is one.

instprop_range instance_properties() const

ObjCMethodDecl * getInstanceMethod(Selector Sel, bool AllowHidden=false) const

ObjCImplementationDecl - Represents a class definition - this is where method definitions are specifi...

Represents an ObjC class declaration.

ObjCIvarDecl * lookupInstanceVariable(IdentifierInfo *IVarName, ObjCInterfaceDecl *&ClassDeclared)

ObjCIvarDecl - Represents an ObjC instance variable.

ObjCIvarRefExpr - A reference to an ObjC instance variable.

ObjCMethodDecl - Represents an instance or class method declaration.

Stmt * getBody() const override

Retrieve the body of this method, if it has one.

ObjCMethodDecl * getCanonicalDecl() override

Retrieves the "canonical" declaration of the given declaration.

bool isSynthesizedAccessorStub() const

Selector getSelector() const

ObjCMethodFamily getMethodFamily() const

Determines the family of this method.

Represents one property declaration in an Objective-C interface.

ObjCIvarDecl * getPropertyIvarDecl() const

Selector getSetterName() const

Selector getGetterName() const

IdentifierInfo * getDefaultSynthIvarName(ASTContext &Ctx) const

Get the default name of the synthesized ivar.

StringRef getNameForSlot(unsigned argIndex) const

Retrieve the name at a given position in the selector.

Stmt - This represents one statement.

ASTContext & getASTContext() override

AnalysisDeclContext * getAnalysisDeclContext(const Decl *D)

BugReporter is a utility class for generating PathDiagnostics for analysis.
