The size in bits of elements of this column.
Most columns have the size fixed by their type but low-precision float columns have variable bit widths.

◆ fFieldId
◆ fFirstElementIndex
| std::int64_t ROOT::Experimental::RColumnDescriptor::fFirstElementIndex = 0U |
|
private |
The absolute value specifies the index for the first stored element for this column.
For deferred columns the absolute value is larger than zero. Negative values specify a suppressed and deferred column.
Definition at line 178 of file RNTupleDescriptor.hxx.
◆ fIndex
| std::uint32_t ROOT::Experimental::RColumnDescriptor::fIndex = 0 |
|
private |
A field can be serialized into several columns, which are numbered from zero to $n$.
Definition at line 180 of file RNTupleDescriptor.hxx.
◆ fLogicalColumnId
The actual column identifier, which is the link to the corresponding field.
Definition at line 170 of file RNTupleDescriptor.hxx.
◆ fPhysicalColumnId
Usually identical to the logical column ID, except for alias columns where it references the shadowed column.
Definition at line 172 of file RNTupleDescriptor.hxx.
◆ fRepresentationIndex
| std::uint16_t ROOT::Experimental::RColumnDescriptor::fRepresentationIndex = 0 |
|
private |
A field may use multiple column representations, which are numbered from zero to $m$.
Every representation has the same number of columns.
