RangeFilter
public class RangeFilter extends Filter (Code)
A Filter that restricts search results to a range of values in a given field.

This code borrows heavily from RangeQuery , but is implemented as a Filter




Constructor Summary
public  RangeFilter(String fieldName, String lowerTerm, String upperTerm, boolean includeLower, boolean includeUpper)
    

Method Summary
public static  RangeFilterLess(String fieldName, String upperTerm)
     Constructs a filter for field fieldName matching less than or equal to upperTerm.
public static  RangeFilterMore(String fieldName, String lowerTerm)
     Constructs a filter for field fieldName matching greater than or equal to lowerTerm.
public  BitSetbits(IndexReader reader)
     Returns a BitSet with true for documents which should be permitted in search results, and false for those that should not.
public  booleanequals(Object o)
     Returns true if o is equal to this.
public  inthashCode()
     Returns a hash code value for this object.
public  StringtoString()
    


Constructor Detail
RangeFilter
public RangeFilter(String fieldName, String lowerTerm, String upperTerm, boolean includeLower, boolean includeUpper)(Code)

Parameters:
  fieldName - The field this range applies to
Parameters:
  lowerTerm - The lower bound on this range
Parameters:
  upperTerm - The upper bound on this range
Parameters:
  includeLower - Does this range include the lower bound?
Parameters:
  includeUpper - Does this range include the upper bound?
throws:
  IllegalArgumentException - if both terms are null or iflowerTerm is null and includeLower is true (similar for upperTermand includeUpper)

Constructs a filter for field fieldName matching greater than or equal to lowerTerm.



bits
public BitSet bits(IndexReader reader) throws IOException(Code)
Returns a BitSet with true for documents which should be permitted in search results, and false for those that should not.



equals
public boolean equals(Object o)(Code)
Returns true if o is equal to this.



hashCode
public int hashCode()(Code)
Returns a hash code value for this object.



toString
public String toString()(Code)
