getConceptualizationOfSpatialRelationships

public String getConceptualizationOfSpatialRelationships()
Returns the Conceptualization of Spatial Relationships parameter of this tool . This parameter is specifies how spatial relationships among features are conceptualized. This is a required parameter.

Returns:
the Conceptualization of Spatial Relationships

setConceptualizationOfSpatialRelationships

public void setConceptualizationOfSpatialRelationships(String conceptualizationOfSpatialRelationships)
Sets the Conceptualization of Spatial Relationships parameter of this tool . This parameter is specifies how spatial relationships among features are conceptualized. This is a required parameter.

Parameters:
conceptualizationOfSpatialRelationships - specifies how spatial relationships among features are conceptualized.

getDistanceMethod

public String getDistanceMethod()
Returns the Distance Method parameter of this tool . This parameter is specifies how distances are calculated from each feature to neighboring features. This is a required parameter.

Returns:
the Distance Method

setDistanceMethod

public void setDistanceMethod(String distanceMethod)

getDistanceBandOrThresholdDistance

public double getDistanceBandOrThresholdDistance()
Returns the Distance Band or Threshold Distance parameter of this tool . This parameter is specifies a cutoff distance for Inverse Distance and Fixed Distance options. Features outside the specified cutoff for a target feature are ignored in analyses for that feature. However, for Zone of Indifference, the influence of features outside the given distance is reduced with distance, while those inside the distance threshold are equally considered. The value entered should match that of the output coordinate system. for the Inverse Distance conceptualizations of spatial relationships, a value of 0 indicates that no threshold distance is applied; when this parameter is left blank, a default threshold value is computed and applied. This default value is the Euclidean distance that ensures every feature has at least one neighbor. this parameter has no effect when Polygon Contiguity or Get Spatial Weights From File spatial conceptualizations are selected. This is an optional parameter.
