The constructor creates the underlying column objects and connects them to either a sink or a source. | |
virtual | ~RFieldBase () |
void | Append (const RFieldValue &value) |
Write the given value into columns. The value object has to be of the same type as the field. | |

RSchemaIterator | begin () |
RSchemaIterator | end () |
void | Flush () const |
Ensure that all received items are written from page buffers to the storage. | |
RFieldValue | GenerateValue () |
Generates an object of the field type and allocates new initialized memory according to the type. | |
virtual RNTupleVersion | GetFieldVersion () const |

std::string | GetName () const |
NTupleSize_t | GetNElements () const |
std::size_t | GetNRepetitions () const |
const RFieldBase * | GetParent () const |
ENTupleStructure | GetStructure () const |
std::vector< const RFieldBase * > | GetSubFields () const |
std::string | GetType () const |
virtual RNTupleVersion | GetTypeVersion () const |

void | Read (const RClusterIndex &clusterIndex, RFieldValue *value) |
void | Read (NTupleSize_t globalIndex, RFieldValue *value) |
Populate a single value with data from the tree, which needs to be of the fitting type. | |
Protected Member Functions | |
void | AppendImpl (const Detail::RFieldValue &value) final |
Operations on values of complex types, e.g. | |
void | ReadGlobalImpl (NTupleSize_t globalIndex, Detail::RFieldValue *value) final |
![]() | |
virtual void | ReadInClusterImpl (const RClusterIndex &clusterIndex, RFieldValue *value) |

![]() | |
static RResult< std::unique_ptr< RFieldBase > > | Create (const std::string &fieldName, const std::string &typeName) |
Factory method to resurrect a field from the stored on-disk type information. | |
static RResult< void > | EnsureValidFieldName (std::string_view fieldName) |
Check whether a given string is a valid field name. | |
![]() | |
std::vector< std::unique_ptr< RColumn > > | fColumns |

RFieldBase * | fParent |
Sub fields point to their mother field. | |
RColumn * | fPrincipalColumn |
Points into fColumns. | |
std::vector< std::unique_ptr< RFieldBase > > | fSubFields |
