Perform a relational operation to determine if one 2D geometry touches another 2D geometry.

Touches operator

Functions

Name	Return Type	Object
`accelerateGeometry`	`boolean`
`execute`	`boolean`
`supportsCurves`

accelerateGeometry

Function

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). See the Acceleration guide topic for more information.

Signature: accelerateGeometry (geometry: GeometryUnion): boolean

Parameters

Parameter	Type	Description	Required
geometry	`GeometryUnion`	The geometry to accelerate.

Returns: boolean
Returns true if the geometry was successfully accelerated.

execute

Function

Perform a touches operation on two geometries.

Signature: execute (geometry1: GeometryUnion, geometry2: GeometryUnion): boolean

Parameters

Parameter	Type	Description	Required
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: 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);

Variables

supportsCurves

Variable

Indicates if the operator supports input geometries that contain curves. The value will always be true.

Type: boolean
