Method Detail

onMapExtentChange

void onMapExtentChange(Extent extent,
                     Point delta,
                     boolean levelChange,
                     LOD lod)

Parameters:

extent - - Gets the extent when after the extent has changed.

delta - - The change in the x and y values from the previous extent. The Point x and y values are in screen units. This point acts as an anchor point, and this part of the map stays within the map region during the zoom process.

levelChange - - When using ArcGIS Server tiled map services, the value is "true" when the user zooms to a new level. The value remains "false" during pan operations.

lod - - When using ArcGIS Server tiled map services, this argument returns characteristics about the level of detail.
