org.apache.lucene.document.column.ColumnFieldAdapter

All Implemented Interfaces:

IndexableField

public abstract sealed class ColumnFieldAdapter
extends Field

Lightweight adapter that presents a Column's current cursor value as an IndexableField so it can be fed through the row-oriented indexing pass (stored fields and term inversion). Holds a fresh tuple cursor over the underlying column; one instance is created per column per batch.

NOTE: This API is for internal purposes only and might change in incompatible ways in the next release.
