schemaLocation: {String} Schema location for a particular minor version.

namespaces: {Object} Mapping of namespace aliases to namespace URIs.

defaultPrefix

collectionName: {String} Name of featureCollection element.

featureName: {String} Element name for features. Default is “sql_statement”.

geometryName: {String} Name of geometry element. Defaults to “geometryProperty”.

xy: {Boolean} Order of the GML coordinate true:(x,y) or false:(y,x) Changing is not recommended, a new Format should be instantiated.

extractAttributes: {Boolean} Could we extract attributes

ZOO.Format.GML

Create a new parser for GML.

Parameters

options {Object} An optional object whose properties will be set on this instance.

read

read: function(data)

Read data from a string, and return a list of features.

Parameters

data {String} data to read/parse.

Returns

{Array(ZOO.Feature)} An array of features.

parseFeature

parseFeature: function(node)

This function is the core of the GML parsing code in ZOO. It creates the geometries that are then attached to the returned feature, and calls parseAttributes() to get attribute data out.

Parameters

node {E4XElement}

Returns

{ZOO.Feature} A vector feature.

parseGeometry: Properties of this object are the functions that parse geometries based on their type.

parseGeometry.point

Given a GML node representing a point geometry, create a ZOO point geometry.

Parameters
