org.apache.solr.search.DocList

All known Subclasses:   org.apache.solr.search.DocSlice,
DocList
public interface DocList extends DocSet(Code)
DocList represents the result of a query: an ordered list of document ids with optional score. This list contains a subset of the complete list of documents actually matched: size() document ids starting at offset().

Method Summary
public  booleanhasScores()
    
public  DocIteratoriterator()
     Returns an iterator that may be used to iterate over the documents in this DocList

The order of the documents returned by this iterator is based on the Sort order of the search that produced it.

public  intmatches()
     Returns the total number of matches for the search (as opposed to just the number collected according to offset() and size()).
public  floatmaxScore()
     The maximum score for the search...
public  intoffset()
     Returns the zero based offset of this list within the total ordered list of matches to the query.
public  intsize()
     Returns the number of ids in this list.
public  DocListsubset(int offset, int len)
     Get a subset of an existing DocList.



Method Detail
hasScores
public boolean hasScores()(Code)
True if scores were retained



iterator
public DocIterator iterator()(Code)
Returns an iterator that may be used to iterate over the documents in this DocList

The order of the documents returned by this iterator is based on the Sort order of the search that produced it. The Scoring information is meaningful only if hasScores() returns true.


See Also:   DocList.hasScores



matches
public int matches()(Code)
Returns the total number of matches for the search (as opposed to just the number collected according to offset() and size()). Hence it's always true that matches() >= size() number of matches for the search(query & any filters)



maxScore
public float maxScore()(Code)
The maximum score for the search... only valid if scores were retained (if hasScores()==true)



offset
public int offset()(Code)
Returns the zero based offset of this list within the total ordered list of matches to the query.



size
public int size()(Code)
Returns the number of ids in this list.



subset
public DocList subset(int offset, int len)(Code)
Get a subset of an existing DocList. Returns null if not possible.
