Member Enumeration Documentation

◆ Kind

enum clang::CodeCompletionContext::Kind

Enumerator
CCC_Other	An unspecified code-completion context.
CCC_OtherWithMacros	An unspecified code-completion context where we should also add macro completions.
CCC_TopLevel	Code completion occurred within a "top-level" completion context, e.g., at namespace or global scope.
CCC_ObjCInterface	Code completion occurred within an Objective-C interface, protocol, or category interface.
CCC_ObjCImplementation	Code completion occurred within an Objective-C implementation or category implementation.
CCC_ObjCIvarList	Code completion occurred within the instance variable list of an Objective-C interface, implementation, or category implementation.
CCC_ClassStructUnion	Code completion occurred within a class, struct, or union.
CCC_Statement	Code completion occurred where a statement (or declaration) is expected in a function, method, or block.
CCC_Expression	Code completion occurred where an expression is expected.
CCC_ObjCMessageReceiver	Code completion occurred where an Objective-C message receiver is expected.
CCC_DotMemberAccess	Code completion occurred on the right-hand side of a member access expression using the dot operator. The results of this completion are the members of the type being accessed. The type itself is available via `CodeCompletionContext::getType()`.
CCC_ArrowMemberAccess	Code completion occurred on the right-hand side of a member access expression using the arrow operator. The results of this completion are the members of the type being accessed. The type itself is available via `CodeCompletionContext::getType()`.
CCC_ObjCPropertyAccess	Code completion occurred on the right-hand side of an Objective-C property access expression. The results of this completion are the members of the type being accessed. The type itself is available via `CodeCompletionContext::getType()`.
CCC_EnumTag	Code completion occurred after the "enum" keyword, to indicate an enumeration name.
CCC_UnionTag	Code completion occurred after the "union" keyword, to indicate a union name.
CCC_ClassOrStructTag	Code completion occurred after the "struct" or "class" keyword, to indicate a struct or class name.
CCC_ObjCProtocolName	Code completion occurred where a protocol name is expected.
CCC_Namespace	Code completion occurred where a namespace or namespace alias is expected.
CCC_Type	Code completion occurred where a type name is expected.
CCC_Name	Code completion occurred where a new name is expected.
CCC_PotentiallyQualifiedName	Code completion occurred where a new name is expected and a qualified name is permissible.
CCC_MacroName	Code completion occurred where an macro is being defined.
CCC_MacroNameUse	Code completion occurred where a macro name is expected (without any arguments, in the case of a function-like macro).
CCC_PreprocessorExpression	Code completion occurred within a preprocessor expression.
CCC_PreprocessorDirective	Code completion occurred where a preprocessor directive is expected.
CCC_NaturalLanguage	Code completion occurred in a context where natural language is expected, e.g., a comment or string literal. This context usually implies that no completions should be added, unless they come from an appropriate natural-language dictionary.
CCC_SelectorName	Code completion for a selector, as in an @selector expression.
CCC_TypeQualifiers	Code completion within a type-qualifier list.
CCC_ParenthesizedExpression	Code completion in a parenthesized expression, which means that we may also have types here in C and Objective-C (as well as in C++).
CCC_ObjCInstanceMessage	Code completion where an Objective-C instance message is expected.
CCC_ObjCClassMessage	Code completion where an Objective-C class message is expected.
CCC_ObjCInterfaceName	Code completion where the name of an Objective-C class is expected.
CCC_ObjCCategoryName	Code completion where an Objective-C category name is expected.
CCC_Recovery	An unknown context, in which we are recovering from a parsing error and don't know which completions we should give.
