Features()

YailList com.google.appinventor.components.runtime.util.MapFactory.MapFeatureCollection.Features

(

)

Gets the list of features contained by the feature collection.

Returns

the list of features in the collection.

Implements com.google.appinventor.components.runtime.util.MapFactory.MapFeatureContainer.

GotFeatures()

void com.google.appinventor.components.runtime.util.MapFactory.MapFeatureCollection.GotFeatures	(	String	url,
		YailList	features
	)

Runs when a call to LoadFromURL(String) succeeds.

features 

will contain a list of feature descriptions that can be used with Map#FeatureFromDescription(YailList) to construct new features.

Parameters

url	the url corresponding to the requested url in LoadFromURL(String)
features	the list of feature descriptions read from the resource at url

Implemented in com.google.appinventor.components.runtime.FeatureCollection.

LoadError()

void com.google.appinventor.components.runtime.util.MapFactory.MapFeatureCollection.LoadError	(	String	url,
		int	code,
		String	message
	)

Runs when an error occurs reading a feature collection from a URL.

Parameters

url	the URL from which a read was attempted.
code	the HTTP status code reported by the server.
message	a human-readable error message sent by the server.

LoadFromURL()

void com.google.appinventor.components.runtime.util.MapFactory.MapFeatureCollection.LoadFromURL

(

String

url

)

Loads the contents from the given

url 

. On success, the GotFeatures(String, YailList) event is run with a description of the features. On error, LoadError(String, int, String) is run with a description of the error. At this time, the only supported format is GeoJSON.

Parameters

url	the URL from which to load a feature collection.

Source() [1/2]

String com.google.appinventor.components.runtime.util.MapFactory.MapFeatureCollection.Source

(

)

Gets the source of the feature collection.

Returns

the last asset or url from which the feature collection was successfully read.

Implemented in com.google.appinventor.components.runtime.FeatureCollection.

Source() [2/2]

void com.google.appinventor.components.runtime.util.MapFactory.MapFeatureCollection.Source

(

String

source

)

Sets the source of the feature collection. This is a designer only property that is used to support loading feature collections in the web editor.

Parameters

source

asset name or url from which to load the feature collection

Implemented in com.google.appinventor.components.runtime.FeatureCollection.

Visible()

boolean com.google.appinventor.components.runtime.util.MapFactory.MapFeatureCollection.Visible

(

)

Gets whether the map feature collection is visible on the map.

Returns

true if the collection should be drawn, otherwise false.

Implemented in com.google.appinventor.components.runtime.FeatureCollection.
