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.

Syntax

public abstract class RandomAccessOrds : SortedSetDocValues

Constructors

RandomAccessOrds()

Sole constructor. (For invocation by subclass constructors, typically implicit.)

Declaration

protected RandomAccessOrds()

Methods

Cardinality()

Returns the cardinality for the current document (previously set by SetDocument(Int32).

Declaration

public abstract int Cardinality()

Returns

Type	Description
System.Int32

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.
