Constructor Details

FacetInterval

public FacetInterval(SchemaField schemaField,
 String startStr,
 String endStr,
 boolean includeLower,
 boolean includeUpper,
 String key)

Constructor that accepts already parsed values of start and end. This constructor can only be used with numeric field types.

Parameters:

schemaField - schemaField for this range

startStr - String representation of the start value of this interval. Can be a "*".

endStr - String representation of the end value of this interval. Can be a "*".

includeLower - Indicates weather this interval should include values equal to start

includeUpper - Indicates weather this interval should include values equal to end

key - String key of this interval

Method Details

updateContext

public void updateContext(org.apache.lucene.index.SortedDocValues sdv)
                   throws IOException

Update the ordinals based on the current reader. This method (or updateContext(SortedSetDocValues) depending on the DocValues type) needs to be called for every reader before includes(long) is called on any document of the reader.

Parameters:

sdv - DocValues for the current reader

Throws:

IOException

updateContext

public void updateContext(org.apache.lucene.index.SortedSetDocValues sdv)
                   throws IOException

Update the ordinals based on the current reader. This method (or updateContext(SortedDocValues) depending on the DocValues type) needs to be called for every reader before includes(long) is called on any document of the reader.

Parameters:

sdv - DocValues for the current reader

Throws:

IOException

includes

public org.apache.solr.request.IntervalFacets.IntervalCompareResult includes(long value)

Method to use to check whether a document should be counted for an interval or not. Before calling this method on a multi-valued and/or non-numeric field make sure you call updateContext(SortedDocValues) or updateContext(SortedSetDocValues) (depending on the DV type). It is OK to call this method without other previous calls on numeric fields (with NumericDocValues)

Parameters:

value - For numeric single value fields, this value should be the long representation of the value of the document in the specified field. For multi-valued and/or non-numeric fields, value should be the ordinal of the term in the current segment

Returns:

• IntervalFacets.IntervalCompareResult.INCLUDED if the value is included in the interval
• IntervalFacets.IntervalCompareResult.GREATER_THAN_END if the value is greater than endLimit
• IntervalFacets.IntervalCompareResult.LOWER_THAN_START if the value is lower than startLimit

• NumericUtils.doubleToSortableLong(double)

toString

public String toString()

Overrides:

toString in class Object

getCount

public int getCount()

Returns:

The count of document that matched this interval

getKey

public String getKey()

Returns:

Human readable key for this interval
