Constructor Detail

CombineThread

public CombineThread(GISFrame gisFrame,
                     int spatialType,
                     int combineType,
                     int combineRule,
                     boolean replaceNull)

Combines the primary and secondary objects stored in the gisFrame.

Parameters:

gisFrame - Frame holding the spatial objects to combine.

spatialType - Type of spatial objects to combine.

combineType - Type of combination (INTERSECTION or UNION).

combineRule - Indicates the type of combination rule to apply. Depends on the spatial object type. For rasters, rule dertermines priority attribute for intersection regions (PRIMARY, SECONDARY or AVERAGE. For vector maps, rule determines if intersection should be of bounding rectangles or polygons in vector map.

replaceNull - Indicates whether null values will be replaced where possible (only applies to raster maps).
