Method Detail

getStart

public String getStart()

Returns:

the start of this range as specified by FacetParams.FACET_RANGE_START parameter

getEnd

public String getEnd()

The end of this facet.range as specified by FacetParams.FACET_RANGE_END parameter

Note that the actual computed end value can be different depending on the FacetParams.FACET_RANGE_HARD_END parameter. See endObj

getInclude

public EnumSet<FacetParams.FacetRangeInclude> getInclude()

Returns:

an EnumSet containing all the values specified via FacetParams.FACET_RANGE_INCLUDE parameter. Defaults to FacetParams.FacetRangeInclude.LOWER if no parameter is supplied. Includes all values from FacetParams.FacetRangeInclude enum if FacetParams.FACET_RANGE_INCLUDE includes FacetParams.FacetRangeInclude.ALL

getGap

public String getGap()

Returns:

the gap as specified by FacetParams.FACET_RANGE_GAP parameter

getGapObj

public Object getGapObj()

Returns:

the computed gap object

isHardEnd

public boolean isHardEnd()

Returns:

the boolean value of FacetParams.FACET_RANGE_HARD_END parameter

getOthers

public EnumSet<FacetParams.FacetRangeOther> getOthers()

Returns:

an EnumSet of FacetParams.FacetRangeOther values specified by FacetParams.FACET_RANGE_OTHER parameter

getMethod

public FacetParams.FacetRangeMethod getMethod()

Returns:

the FacetParams.FacetRangeMethod to be used for computing ranges determined either by the value of FacetParams.FACET_RANGE_METHOD parameter or other internal constraints.

getMinCount

public int getMinCount()

Returns:

the minimum allowed count for facet ranges as specified by FacetParams.FACET_MINCOUNT

getSchemaField

public SchemaField getSchemaField()

Returns:

the SchemaField instance representing the field on which ranges have to be calculated

isGroupFacet

public boolean isGroupFacet()

Returns:

the boolean value specified by GroupParams.GROUP_FACET parameter

getFacetRanges

public List<RangeFacetRequest.FacetRange> getFacetRanges()

Returns:

a List of RangeFacetRequest.FacetRange objects representing the ranges (gaps) for which range counts are to be calculated.

getStartObj

public Object getStartObj()

Returns:

The computed start value of this range

getEndObj

public Object getEndObj()

The end of this facet.range as calculated using the value of facet.range.end parameter and facet.range.hardend. This can be different from the value specified in facet.range.end if facet.range.hardend=true
