Detailed Description

Scope - A scope is a transient data structure that is used while parsing the program.

It assists with resolving identifiers to the appropriate declaration.

Member Enumeration Documentation

◆ ScopeFlags

enum clang::Scope::ScopeFlags

ScopeFlags - These are bitfields that are or'd together when creating a scope, which defines the sorts of things the scope contains.

Enumerator
NoScope
FnScope	This indicates that the scope corresponds to a function, which means that labels are set here.
BreakScope	This is a while, do, switch, for, etc that can have break statements embedded into it.
ContinueScope	This is a while, do, for, which can have continue statements embedded into it.
DeclScope	This is a scope that can contain a declaration. Some scopes just contain loop constructs but don't contain decls.
ControlScope	The controlling scope in a if/switch/while/for statement.
ClassScope	The scope of a struct/union/class definition.
BlockScope	This is a scope that corresponds to a block/closure object. Blocks serve as top-level scopes for some objects like labels, they also prevent things like break and continue. BlockScopes always have the FnScope and DeclScope flags set as well.
TemplateParamScope	This is a scope that corresponds to the template parameters of a C++ template. Template parameter scope starts at the 'template' keyword and ends when the template declaration ends.
FunctionPrototypeScope	This is a scope that corresponds to the parameters within a function prototype.
FunctionDeclarationScope	This is a scope that corresponds to the parameters within a function prototype for a function declaration (as opposed to any other kind of function declarator). Always has FunctionPrototypeScope set as well.
AtCatchScope	This is a scope that corresponds to the Objective-C @catch statement.
ObjCMethodScope	This scope corresponds to an Objective-C method body. It always has FnScope and DeclScope set as well.
SwitchScope	This is a scope that corresponds to a switch statement.
TryScope	This is the scope of a C++ try statement.
FnTryCatchScope	This is the scope for a function-level C++ try or catch scope.
OpenMPDirectiveScope	This is the scope of OpenMP executable directive.
OpenMPLoopDirectiveScope	This is the scope of some OpenMP loop directive.
OpenMPSimdDirectiveScope	This is the scope of some OpenMP simd directive. For example, it is used for 'omp simd', 'omp for simd'. This flag is propagated to children scopes.
EnumScope	This scope corresponds to an enum.
SEHTryScope	This scope corresponds to an SEH try.
SEHExceptScope	This scope corresponds to an SEH except.
SEHFilterScope	We are currently in the filter expression of an SEH except block.
CompoundStmtScope	This is a compound statement scope.
ClassInheritanceScope	We are between inheritance colon and the real class/struct definition scope.
CatchScope	This is the scope of a C++ catch statement.
Unused	This bit is currently unused.
OpenMPOrderClauseScope	This is a scope of some OpenMP directive with order clause which specifies concurrent.
LambdaScope	This is the scope for a lambda, after the lambda introducer. Lambdas need two FunctionPrototypeScope scopes (because there is a template scope in between), the outer scope does not increase the depth of recursion.
OpenACCComputeConstructScope	This is the scope of an OpenACC Compute Construct, which restricts jumping into/out of it. We also use this to represent 'combined' constructs, since they have the same behavior.
OpenACCLoopConstructScope	This is the scope of an OpenACC Loop/Combined construct, which is used to determine whether a 'cache' construct variable reference is legal.
TypeAliasScope	This is a scope of type alias declaration.
FriendScope	This is a scope of friend declaration.
