◆ addReplacement()

static void clang::reorder_fields::addReplacement ( SourceRange  Old,
SourceRange  New,
const ASTContext &  Context,
std::map< std::string, tooling::Replacements > &  Replacements 
)
static

Replaces one range of source code by another.

◆ findDefinition()

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

Finds the definition of a record by name.

Returns
nullptr if the name is ambiguous or not found.

◆ 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

◆ 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.

Definition at line 57 of file ReorderFieldsAction.cpp.

References Field, and Name.

◆ 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.

Definition at line 124 of file ReorderFieldsAction.cpp.

◆ 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
