Class Link

java.lang.Object
org.apache.sis.internal.storage.gpx.Link
All Implemented Interfaces:
org.opengis.metadata.citation.OnlineResource
public final class Link extends Object implements org.opengis.metadata.citation.OnlineResource
A link to an external resource (Web page, digital photo, video clip, etc) with additional information. This element provides 3 properties:
  • The uri, which is the only mandatory property.
  • The text to show for the link.
  • The MIME type.
Those properties can be read or modified directly. All methods defined in this class are bridges to the ISO 19115 metadata model and can be ignored if the user only wants to manipulate the GPX model.
