Methods

Name Returns Description
add(child[, index])

IGeoObjectCollection

Adds (inserts) a child geo object to the collection.

each(callback[, context])

Calls a handler function for each child geo object.

get(index)

IGeoObject

Returns a child geo object with the specified index.

getBounds()

Number[][]|null

Returns geographical coordinates of the area that covers the collection and its child geo objects.

getIterator()

IIterator

Returns iterator for the collection.

getLength()

Integer

Returns length of the collection.

getMap()

Map

Returns reference to the map.

Inherited from IParentOnMap.

getPixelBounds()

Number[][]|null

Returns global pixel coordinates of the area that spans the collection and its child geo objects.

indexOf(object)

Integer

Returns index of the child geo object. If the geo object cannot be found in the collection, -1 is returned.

remove(child)

IGeoObjectCollection

Removes a child geo object from the collection.

removeAll()

IGeoObjectCollection

Clears the collection.

set(index, child)

IGeoObjectCollection

Adds a new child geo object to the collection.

splice(index, number)

IGeoObjectCollection

Removes geo objects from the collection. If necessary, puts other objects in their place. Objects that will be added in place of the deleted ones are passed as additional parameters (after the "number" parameter).
