Methods

create

create(elements): MultiIndexSet<TypeIDType>
Create a type index from a set of parsed STEP elements.
Parameters
- elements: StepIndexEntry<TypeIDType>[]
  The elements to type index.
Returns MultiIndexSet<TypeIDType>
The created multi-set index.
- Defined in step/indexing/step_type_indexer.ts:128

createFor

createFor(index): MultiIndexSet<TypeIDType>
Create a type index from either index form — the parsed object array or the columnar index (M7).
Parameters
- index: StepIndexColumns<TypeIDType> | StepIndexEntry<TypeIDType>[]
  The element index, object or columnar.
Returns MultiIndexSet<TypeIDType>
The created multi-set index.
- Defined in step/indexing/step_type_indexer.ts:32

createFromColumns

createFromColumns(columns): MultiIndexSet<TypeIDType>
Create a type index straight from the columnar index — the same membership create produces from the unfolded object array: every row's concrete type (top-level + inline; −1 rows skipped) plus the multi-mapping subtypes of retained complex entries at their parent's dense index.
Parameters
- columns: StepIndexColumns<TypeIDType>
  The columnar index.
Returns MultiIndexSet<TypeIDType>
The created multi-set index.
