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.Inherited Members

Syntax
public abstract class RandomAccessOrds : SortedSetDocValuesConstructors
RandomAccessOrds()
Sole constructor. (For invocation by subclass constructors, typically implicit.)

| int |
Methods
OrdAt(int)
Retrieve the ordinal for the current document (previously set by SetDocument(int) at the specified index.
An index ranges from0 to Cardinality-1.
The first ordinal value is at index 0, the next at index 1,
and so on, as for array indexing.
