Constructor Details

HeatmapFacetMap

public HeatmapFacetMap(String fieldName)

Method Details

getThis

public HeatmapFacetMap getThis()

Specified by:

getThis in class JsonFacetMap<HeatmapFacetMap>

withSubFacet

public HeatmapFacetMap withSubFacet(String facetName,
 JsonFacetMap map)

Overrides:

withSubFacet in class JsonFacetMap<HeatmapFacetMap>

setRegionQuery

public HeatmapFacetMap setRegionQuery(String queryString)

Indicate the region to compute the heatmap facet on.

Defaults to the "world" ("[-180,-90 TO 180,90]")

setGridLevel

public HeatmapFacetMap setGridLevel(int individualCellSize)

Indicates the size of each cell in the computed heatmap grid

If not set, defaults to being computed by distErrPct or distErr

Parameters:

individualCellSize - the forced size of each cell in the heatmap grid

See Also:

• setDistErr(double)
• setDistErrPct(double)

setDistErrPct

public HeatmapFacetMap setDistErrPct(double distErrPct)

A fraction of the heatmap region that is used to compute the cell size.

Defaults to 0.15 if not specified.

See Also:

• setGridLevel(int)
• setDistErr(double)

setDistErr

public HeatmapFacetMap setDistErr(double distErr)

Indicates the maximum acceptable cell error distance.

Used to compute the size of each cell in the heatmap grid rather than specifying setGridLevel(int)

Parameters:

distErr - a positive value representing the maximum acceptable cell error.

See Also:

• setGridLevel(int)
• setDistErrPct(double)

setHeatmapFormat

public HeatmapFacetMap setHeatmapFormat(HeatmapFacetMap.HeatmapFormat format)

Sets the format that the computed heatmap should be returned in.

Defaults to 'ints2D' if not specified.
