Class: DistanceTool

OM.tool. DistanceTool

new DistanceTool(map, options)

A DistanceTool can be used to measure linear distances on the map by drawing
a series of connected line segments. It is a subclass of OM.tool.Tool.

Parameters:
Name Type Description
map OM.Map

The map instance to be associated with this tool
options object

This is an object literal that specifies the initial DistanceTool options. It can have the following properties.


  • unit {String} Optional. The unit for the distance tool.
  • transformToGeodetic {boolean} Optional. If true, transform To Geodetic; default value is true.
  • dataSource {String} Optional. The datasource for the distance tool.If client side supports the srid transform,this param is not required,
    if client side does not support the srid transform,this param is required.
Returns:

An instance of OM.tool.DistanceTool

This function should be called once to set the style for the vertices (i.e. the point style) and
once to set the style for the line segments.

Parameters:
Name Type Description
options int

An object with two properties, type and style, which
defines the geometry type and the style.


  • type Specifies the geometry type. Must be one of two pre-defined constants:
    OM.tool.DistanceTool.TYPE_POINT or OM.tool.DistanceTool.TYPE_LINESTRING.

  • style {OM.style.Style} The style to use

Returns:
Type
void

setStyle(style)
