Creates a map as a child of something .
provider is one of TYPE_ constants.
optionsObject may contain:
fix - one of FIX_
constants, used when markers are too close to each
other
fixDistance - distance for
shifting markers
fixEpsilon - euclidean distance
limit of markers to be taken as identical (in degrees)
The specificOptions object may contain any
engine-specific options, such as {draggableCursor:
crosshair} for Google Maps.
Methods
OAT.Map::addTypeControl()
Adds a 'map type' control to the map.
OAT.Map::addMapControl()
Adds a 'map navigation' control to the map.
OAT.Map::setMapType(type)
Sets map type to one of MAP_ constants.
OAT.Map::centerAndZoom(lat, long, zoom)
Pans the map to given lat and long
coordinates and zooms. zoom ranges from 0 (far) to 16
(close).
OAT.Map::setZoom(zoom)
Changes current zoom level.
OAT.Map::getZoom()
Returns current zoom level.
OAT.Map::addMarker(group, lat, long, file, w, h, callback)
Adds a marker to the map. Marker belongs to marker
group group (any internal value) and is located at
coordinates specified in lat and long .
file specifies an image file name ( w and
h are its dimensions), false when default image should
be used. Finally, callback is a function to be
executed when user clicks marker.
OAT.Map::removeMarker(marker)
Removes existing marker .
OAT.Map::removeMarkers(group)
Removes all markers which belong to group .
OAT.Map::openWindow(marker, something)
Opens window, anchored to marker . something
is a DOM node to be appended into window.
OAT.Map::closeWindow()
Closes opened window.
OAT.Map::optimalPosition(pointArray)
Zooms map so all points specified in pointArray (array
of 2-element arrays) can be visible simultaneously.
OAT.Map::geoCode(address, callback)
Performs a geocoding lookup of address . When
result is returned, callback is executed. Its only
argument is false when no result was found, or an array of
[lat,long] .
