Class RandomAccessOrds

Extension of SortedSetDocValues that supports random access to the ordinals of a document.

Operations via this API are independent of the iterator api (NextOrd()) and do not impact its state.

Codecs can optionally extend this API if they support constant-time access to ordinals for the document.

OrdAt(Int32)

Retrieve the ordinal for the current document (previously set by SetDocument(Int32) at the specified index.

An index ranges from 0 to Cardinality()-1. The first ordinal value is at index 0, the next at index 1, and so on, as for array indexing.

Declaration
public abstract long OrdAt(int index)
Parameters
Type Name Description
System.Int32 index

index of the ordinal for the document.

Returns
Type Description
System.Int64

ordinal for the document at the specified index.
