Enum Class Geometries

Object
Enum<Geometries>
Geometries
All Implemented Interfaces:
Serializable, Comparable<Geometries>, Constable
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<? extends Geometry> aClass = ...
 Geometries type = Geometries.getForBinding( aClass );

  • Enum Constant Details

  • Method Details

    • values

      public static Geometries[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static Geometries valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class 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

    • toString

      public String toString()
      Equivalent to getName().
      Overrides:
      toString in class Enum<Geometries>
      Returns:
      the name of this type

    • 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
