Syntax
public class OrdinalMapConstructors
| Improve this Doc View SourceOrdinalMap(Object, TermsEnum[])
Creates an ordinal map that allows mapping ords to/from a merged
space from subs.
Declaration
public OrdinalMap(object owner, TermsEnum[] subs)Parameters
| Type | Name | Description |
|---|---|---|
| System.Object | owner | a cache key |
| TermsEnum[] | subs | TermsEnums that support Ord. They need not be dense (e.g. can be FilteredTermsEnums). |
Exceptions
| Type | Condition |
|---|---|
| System.IO.IOException | if an I/O error occurred. |
Properties
