Classes

Author type, holds information of the creator of the GPX file. A subclass of GPXPerson.

A value type that represents bounds based off GPX v1.1 schema’s boundsType.

This is meant for having two pairs of longitude and latitude, signifying the maximum and minimum, defining the extent / boundaries of a particular element.

Simple class for some basic lossy compression.

A value type for representing copyright info

Copyight information also includes additional attributes.

Supported attributes:

• Year of first publication
• License of the file

A root class for all element types

All element types such as waypoints, tracks or routes are subclasses of GPXElement. This class brings important methods that aids towards creation of a GPX file.

Used for handling email types

Email is seperated as two variables in order to prevent email harvesting. The GPX v1.1 schema requires that.

For example, an email of “yourname@thisisawebsite.com”, would have an id of ‘yourname’ and a domain of ‘thisisawebsite.com’.

For adding/obtaining data stored as extensions in GPX file.

Typical GPX extended data, would have data that should be inbetween the open and close tags of <extensions>

This class represents the extended data in a GPX file.

A duplicated class of GPXRawElement

This class is a public class as it is representative of all child extension tag types.

It is also inherits GPXElement, and therefore, works like any other ‘native’ element types.

A value type that can hold a web link to a external resource, or external information about a certain attribute.

In addition to having a URL as its attribute, it also accepts the following as child tag:

• type of content
• text of web link (probably a description kind of thing)

A value type that represents the metadata header of a GPX file.

Information about the GPX file should be stored here.

• Supported Info types:
  • Name
  • Description

  Author

  Author Info

  Copyright

  Date

  • Bounds
  • Also supports extensions

An event-driven parser (SAX parser), currently parses GPX v1.1 files only.

This parser is already setted up, hence, does not require any handling, and will parse files directly as objects. To get the parsed data from a GPX file, simply initialize the parser, and get the GPXRoot from parsedData().

A value type that is designated to hold information regarding the person or organisation who has created the GPX file.

• This class (ptType) is added to conform with the GPX v1.1 schema.

ptType of GPX schema. Not supported in GPXRoot, nor GPXParser’s parsing.

• This class (ptsegType) is added to conform with the GPX v1.1 schema.

ptsegType of GPX schema. Not supported in GPXRoot, nor GPXParser’s parsing.

Creation of a GPX file or GPX formatted string starts here

GPXRoot holds all metadata, waypoints, tracks, routes and extensions types together before being packaged as a GPX file, or formatted as per GPX schema’s requirements.

Value type that represents a route, or rteType in GPX v1.1 schema.

The route can represent the planned route of a specific trip.

A route point is just like a waypoint or track point, but is suited to be part of a route.

These route points in collective, forms a valid route.

Represents trkType of GPX v1.1 schema.

A track can hold track segments, along with additional information regarding the track.

Tracks are meant to show the start and finish of a journey, through the track segments that it holds.

A track point is just like a waypoint or route point, but is suited to be part of a track segment.

A bunch of track points can be used to form a track segement, while track segments form a track. (though a single track segment itself is enough to form a track.)

A track segment that holds data on all track points in the particular segment.

Does not hold additional information by default.

A value type that represents waypoint based off GPX v1.1 schema’s wptType.

According to the GPX schema, the waypoint type can represent the following:

• a waypoint
• a point of interest
• a named feature on a map

The waypoint should at least contain the attributes of both latitude and longitude in order to be considered a valid waypoint. Most attributes are optional, and are not required to be implemented.
