Method Details

overlaps

public org.springframework.http.ResponseEntity<Boolean> overlaps(String[] poly,
 String[] type)

Checks whether an area, i.e. the Polygon defined by the array poly overlaps at least one of the provided regions. If none are given, all available region types will be considered. For longer arrays, using the overlapspoly() method with a RestPolygon is recommended, and for high lengths in fact necessary.

Specified by:

overlaps in interface OverlapController

Parameters:

poly - String array containing latitude (uneven fields)/longitude (uneven fields) pairs in Double format, which together describe an area to be compared to a number of specified regions

type - String array used to determine which regions (specified in application.yml) to check. If the array parameter is null or empty, all available region types will be considered

Returns:

HttpStatus 200 and true if the polygon overlaps one or more of the specified regions (all known regions if none were specified), false otherwise OR HttpStatus 400 and an error message if the input was invalid OR HttpStatus 500 and an error message if the input was valid but the implementation is pending or a problem occurred while trying to process a shape file

overlapspoly

public org.springframework.http.ResponseEntity<Boolean> overlapspoly(String[] type,
 RestPolygon restPolygon)

Checks whether an area defined by a RestPolygin overlaps at least one of the provided regions. If none are given, all available region types will be considered.

Specified by:

overlapspoly in interface OverlapController

Parameters:

type - String array used to determine which regions (specified in application.yml) to check. If the array parameter is null or empty, all available region types will be considered

restPolygon - RestPolygon describing an area to be compared to a number of specified regions

Returns:

HttpStatus 200 and true if the polygon overlaps one or more of the specified regions (all known regions if none were specified), false otherwise OR HttpStatus 400 and an error message if the input was invalid OR HttpStatus 500 and an error message if the input was valid but the implementation is pending or a problem occurred while trying to process a shape file
