Private Attributes | |
DescriptorId_t | fFieldId = kInvalidDescriptorId |
Every column belongs to one and only one field. | |
std::uint64_t | fFirstElementIndex = 0U |
Specifies the index for the first stored element for this column. | |
std::uint32_t | fIndex |
A field can be serialized into several columns, which are numbered from zero to $n$. | |
DescriptorId_t | fLogicalColumnId = kInvalidDescriptorId |
The actual column identifier, which is the link to the corresponding field. | |
RColumnModel | fModel |
Contains the column type and whether it is sorted. | |
DescriptorId_t | fPhysicalColumnId = kInvalidDescriptorId |
Usually identical to the logical column ID, except for alias columns where it references the shadowed column. | |
