new HereTileLayer(name, config)
OM.layer.HereTileLayer defines a map tile layer that displays HERE Maps using
HERE Map Tile API 3.0.
To use HERE Maps as a tile layer, your usage of the maps must meet the Terms
of Service defined by HERE.
HERE Map tiles are rendered in a projection system known as Spherical Mercator.
If you need to overlay your own spatial data on top of the HERE Maps tile layer, you
must set up the database to properly handle coordinate system transformation between
the HERE Maps coordinate system and your own data coordinate system if they are not
the same. Please refer to MapViewer User's Guide for more information.

(hide the layer).- Inherited From:
Returns:
void}

setVisibleBound(bound)
-
Set a bound (MBR) for the layer visibility. Only content within the supplied bound will be rendered.

parameter of setZIndex is less than 1, it will be set to 1. If it is
greater than n, it will be set to n. If z-Index value, newIndex, is already assigned
to another layer, then it will still be assigned to the current layer (on which this function is invoked).

- Type
- int
-

Set the zoom level range within which this layer is visible. By default
a layer is set to be visible between a minmum zoom level of 0 and a maximum

Name Type Description minLevel
int Specifies the min level. The layer will not be
visible if the zoom level is lower than this vlaue.maxLevel
int Specifies the max level. The layer will not be
visible if the zoom level is higher than this value.- Inherited From:
