Class Description
A DomMarker is a visual representation of a location on a map in the form of a fully styleable and scripteable DOM element.
It should be only used where small numbers of markers with dynamic style and/or scripted icons are to be displayed on the map (for example animated interactive SVG). Otherwise a H.map.Marker should be preferred for performance reasons.
Constructor Details
H.map.DomMarker(position, opt_options)
- Parameters:
-
position
: -
{(H.geo.IPoint | H.geo.MultiPoint)}
- The geographic location(s) of the marker
-
opt_options
: -
{H.map.DomMarker.Options=} [optional]
- The options to initialize the marker
Method Details
getGeometry () : {(H.geo.Point | H.geo.MultiPoint)}
To obtain the marker's location(s). If you modify the obtained geometry, you must call setGeometry(geometry)
afterwards to not violate the integrity of the marker.
- Returns:
-
{(H.geo.Point | H.geo.MultiPoint)}
setGeometry (geometry) : {H.map.AbstractMarker}
To Set the marker's geographic location(s). If you modify the given geometry afterwards, you must call setGeometry(geometry)
again to not violate the integrity of the marker.
- Parameters:
-
geometry
: -
{(H.geo.IPoint | H.geo.MultiPoint)}
- Returns:
-
{H.map.AbstractMarker}
- the marker itself
- Throws:
-
{H.lang.InvalidArgumentError}
- if the given geometry is not valid
getIcon () : {!(H.map.Icon | H.map.DomIcon)}
This method retrieves the current icon associated with the given marker.
- Returns:
-
{!(H.map.Icon | H.map.DomIcon)}
setIcon (icon) : {H.map.AbstractMarker}
This method sets the marker icon.
- Parameters:
-
icon
: -
{!(H.map.Icon | H.map.DomIcon)}
- The new marker icon
- Returns:
-
{H.map.AbstractMarker}
- The marker object itself
- Throws:
-
{H.lang.InvalidArgumentError}
getId () : {*}
This method retrieves the ID of the given object.
- Returns:
-
{*}
- The identifier of the given object.
setVisibility (opt_visibility) : {H.map.Object}
This method sets the visibility of the given object.
- Parameters:
-
opt_visibility
: -
{boolean=} [optional]
- Indicates whether the map object should be visible.
- Returns:
-
{H.map.Object}
- The given object
getVisibility (opt_effective) : {boolean}
This method retrieves a value indicating the visibility of the given object.
- Parameters:
-
opt_effective
: -
{boolean=} [optional]
- Indicates that the effective visibility is requested. In this case the visibility of all possible ancestor groups is also taken into account
- Returns:
-
{boolean}
- A value indicating if the object is visible (
true
) or notfalse
getZIndex () : {(number | undefined)}
This method retrieves the z-index of the given object.
- Returns:
-
{(number | undefined)}
- A value reflecting the z-index of the given object.
setZIndex (zIndex) : {H.map.Object}
This method sets the z-index of the given object.
- Parameters:
-
zIndex
: -
{(number | undefined)}
- A value indicating the new z-index
- Returns:
-
{H.map.Object}
- The given object
compareZOrder (other) : {number}
This method compares the rendering z-order of the given object with another object. (The 'given object' mean the object on which the method has been invoke.)
- Parameters:
-
other
: -
{H.map.Object}
- The map object with which to compare the given object.
- Returns:
-
{number}
- A value lower than
0
indicates that the given object has a lower z-order.0
indicates that both objects have the same z-order. A value greater than0
, indicates that the given object has a higher z-order.
getParentGroup () : {?H.map.Group}
This method retrieves the parent group which contains the given object or null
if the object is not contained in any group.
- Returns:
-
{?H.map.Group}
- An object representing the containing group object or
null
if the given object is not contained in any group.
getRootGroup () : {!H.map.Object}
The root object to which the given object is attached or the object itself if it is not attached to another.
- Returns:
-
{!H.map.Object}
- An object representing the root group for the given object or the given object if it is not part of a group.
contains (object) : {boolean}
This method checks whether the received object is an inclusive descendant of the given object.
- Parameters:
-
object
: -
{*}
- The object to check.
- Returns:
-
{boolean}
-
true
if the given object is contained in the given object, otherwisefalse
getProvider () : {?H.map.provider.ObjectProvider}

- Returns:
-
{?H.map.provider.ObjectProvider}
- An object representing the provider
getInvalidations () : {H.map.provider.Invalidations}

- The flags indicating the types of changes to the given object
- Returns:
-
{boolean}
- Indicates whether a validation was executed (only if the object has a provider)

dispose ()
This method removes listeners from the given object. Classes that extend EventTarget
may need to override this method in order to remove references to DOM Elements and additional listeners.
