Enum Geometries

  • All Implemented Interfaces:
    Serializable, Comparable<Geometries>
    public enum Geometries
extends Enum<Geometries>
    Constants to identify JTS geometry types, reducing the need for boiler-plate code such as this... 
    
 if (Polygon.class.isAssignableFrom(myObject.getClass()) ||
         MultiPolygon.class.isAssignableFrom(myObject.getClass())) {
     // do polygon thing
     ...
 } else if (LineString.class.isAssignableFrom(myObject.getClass()) ||
         MultiLineString.class.isAssignableFrom(myObject.getClass())) {
     // do line thing
     ....
 } else {
     // do point thing
     ....
 }
    Instead you can do this... 
    
 Geometries geomType = Geometries.get(myObject);
 switch (geomType) {
     case POLYGON:
     case MULTIPOLYGON:
         // do polygon thing
         break;

     case LINESTRING:
     case MULTILINESTRING:
         // do line thing
         break;

     case POINT:
     case MULTIPOINT:
         // do point thing
         break;

     default:
         // e.g. unspecified Geometry, GeometryCollection
         break;
 }
    You can also work with Class objects... 
    
 Class aClass = ...
 Geometries type = Geometries.getForBinding( aClass );

    • Method Detail

      • values

        public static Geometries[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows: 
        for (Geometries c : Geometries.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static Geometries valueOf​(String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        IllegalArgumentException - if this enum type has no constant with the specified name
        NullPointerException - if the argument is null

      • getBinding

        public Class<? extends Geometry> getBinding()
        Return the Geometry class associated with this type.
        Returns:
        the Geometry class

      • getSQLType

        public Integer getSQLType()
        Return the integer SQL type code for this geometry type.
        Returns:
        integer code

      • getName

        public String getName()
        Return a name for this type that is suitable for text descriptions.
        Returns:
        the name

      • getSimpleName

        public String getSimpleName()
        Get the 'simple name'. Returns the same value as getName() except for MULTIPOINT, MULTILINESTRING and MULTIPOLYGON, for which it returns the name without the 'Multi' prefix.
        Returns:
        the simple name

      • get

        public static Geometries get​(Geometry geom)
        Get the Geometries for the given object.
        Parameters:
        geom - a JTS Geometry object
        Returns:
        the Geometries for the argument's class, or null if the argument is null

      • getForBinding

        public static Geometries getForBinding​(Class<? extends Geometry> geomClass)
        Get the Geometries for the given Geometry class.
        Parameters:
        geomClass - the class
        Returns:
        the constant for this class

      • getForName

        public static Geometries getForName​(String name)
        Get the Geometries for the specified name.
        Parameters:
        name - The name of the geometry, eg: "POINT"
        Returns:
        The constant for the name.

      • getForSQLType

        public static Geometries getForSQLType​(int sqlType)
        Get the Geometries with the given integer SQL type code.
        Parameters:
        sqlType - the code to look up.
        Returns:
        the matching type or null if no match was found
