Enum GeometryLibrary

All Implemented Interfaces:
Serializable, Comparable<Geometry­Library>, Constable

public enum GeometryLibrary extends Enum<GeometryLibrary>
Some libraries providing geometric objects or topological operations. Apache SIS uses its own implementation for the most basic objects like direct positions and envelopes, and can delegate to one of the enumerated libraries for more complex geometries. All those libraries are optional.

      public static final GeometryLibrary JAVA2D
      The Java 2D Graphics and Imaging library. This library does not provide as many topological operations than other libraries, but is available on most standard Java environments and constitute a reliable fallback when no other library is available.
      Implementation classes
      Geometry type Class name
      GeometryType.POINT java.awt.geom.Point2D
      GeometryType.LINEAR java.awt.Shape
      GeometryType.AREAL java.awt.Shape
      Note that contrarily to JTS and ESRI libraries, a point does not extend any root geometry class in Java2D.

    • ESRI

      public static final GeometryLibrary ESRI
      The ESRI geometry API library. This library can be used for spatial vector data processing. It is used in ESRI GIS Tools for Hadoop and has an Android port. The library is available under Apache 2 license.

      public static final GeometryLibrary JTS
      The Java Topology Suite (JTS) library. This open source library provides an object model for Euclidean planar geometry together with a set of fundamental geometric functions. The library is licensed under Eclipse Distribution License.

    • values

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

    • valueOf

      public static GeometryLibrary 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.)
      name - the name of the enum constant to be returned.
      the enum constant with the specified name
      Illegal­Argument­Exception - if this enum type has no constant with the specified name
      Null­Pointer­Exception - if the argument is null
