findDefinition()

static const RecordDecl * clang::reorder_fields::findDefinition ( StringRef  RecordName, ASTContext &  Context  )

static

findMembersUsedInInitExpr()

static SmallSetVector< FieldDecl *, 1 > clang::reorder_fields::findMembersUsedInInitExpr ( const CXXCtorInitializer *  Initializer, ASTContext &  Context  )

static

Find all member fields used in the given init-list initializer expr that belong to the same record.

Returns

a set of field declarations, empty if none were present

getFullFieldSourceRange()

static SourceRange clang::reorder_fields::getFullFieldSourceRange ( const FieldDecl &  Field, const ASTContext &  Context  )

static

Returns the full source range for the field declaration up to (not including) the trailing semicolumn, including potential macro invocations, e.g.

getNewFieldsOrder()

static SmallVector< unsigned, 4 > clang::reorder_fields::getNewFieldsOrder ( const RecordDecl *  Definition, ArrayRef< std::string >  DesiredFieldsOrder  )

static

Calculates the new order of fields.

Returns

empty vector if the list of fields doesn't match the definition.

reorderFieldsInConstructor()

static void clang::reorder_fields::reorderFieldsInConstructor ( const CXXConstructorDecl *  CtorDecl, ArrayRef< unsigned >  NewFieldsOrder, ASTContext &  Context, std::map< std::string, tooling::Replacements > &  Replacements  )

static

Reorders initializers in a C++ struct/class constructor.

A constructor can have initializers for an arbitrary subset of the class's fields. Thus, we need to ensure that we reorder just the initializers that are present.

reorderFieldsInDefinition()

static bool clang::reorder_fields::reorderFieldsInDefinition ( const RecordDecl *  Definition, ArrayRef< unsigned >  NewFieldsOrder, const ASTContext &  Context, std::map< std::string, tooling::Replacements > &  Replacements  )

static

Reorders fields in the definition of a struct/class.

At the moment reordering of fields with different accesses (public/protected/private) is not supported.

Returns

true on success.

reorderFieldsInInitListExpr()

static bool clang::reorder_fields::reorderFieldsInInitListExpr ( const InitListExpr *  InitListEx, ArrayRef< unsigned >  NewFieldsOrder, const ASTContext &  Context, std::map< std::string, tooling::Replacements > &  Replacements  )

static

Reorders initializers in the brace initialization of an aggregate.

At the moment partial initialization is not supported.

Returns

true on success
