## Interface SegmentCacheable

- All Known Implementing Classes:
    ConstantScoreWeight, DisjunctionMaxQuery.DisjunctionMaxWeight, DoubleValuesSource, FilterWeight, LongValuesSource, SpanContainingQuery.SpanContainingWeight, org.apache.lucene.search.spans.SpanContainQuery.SpanContainWeight, SpanNearQuery.SpanNearWeight, SpanNotQuery.SpanNotWeight, SpanOrQuery.SpanOrWeight, SpanPositionCheckQuery.SpanPositionCheckWeight, SpanTermQuery.SpanTermWeight, SpanWeight, SpanWithinQuery.SpanWithinWeight, Weight

      public interface SegmentCacheable

  Interface defining whether or not an object can be cached against a `LeafReader` Objects that depend only on segment-immutable structures such as Points or postings lists can just return `true` from `isCacheable(LeafReaderContext)` Objects that depend on doc values should return `DocValues.isCacheable(LeafReaderContext, String...)`, which will check to see if the doc values fields have been updated. Updated doc values fields are not suitable for cacheing. Objects that are not segment-immutable, such as those that rely on global statistics or scores, should return `false`
