Accelerate a geometry.

touchesOperator

Perform a touches operation on two geometries.

touchesOperator

Method Details

accelerateGeometry

Method
accelerateGeometry(geometry){Boolean}

Accelerate a geometry. This method prepares the geometry for faster touches operations when the same geometry is tested multiple times (e.g. in a loop with hundreds of iterations).

Parameter
geometry GeometryUnion

The geometry to accelerate.

Returns
Type Description
Boolean Returns true if the geometry was successfully accelerated.

execute

Method
execute(geometry1, geometry2){Boolean}

Perform a touches operation on two geometries.

Parameters
geometry1 GeometryUnion

The base geometry that is tested for the "touches" relationship with geometry2.

geometry2 GeometryUnion

The comparison geometry that is tested for the "touches" relationship with geometry1.

Returns
Type Description
Boolean Returns true if the two geometries touch.
Example
// Returns true if the line vertex touches the edge of the polygon
const isTouching = touchOperator.execute(polygon, line);
