AI-generated Key Takeaways
-
The
containsmethod returns true if and only if one geometry contains the other. -
The
containsmethod is used with a Polygon object and takes arightgeometry, optionalmaxError, and optionalprojas arguments. -
The
containsmethod returns a Boolean value.

| Argument | Type | Details |
|---|---|---|
|
this:
left
|
Geometry | The geometry used as the left operand of the operation. |
right
|
Geometry | The geometry used as the right operand of the operation. |
maxError
|
ErrorMargin, default: null | The maximum amount of error tolerated when performing any necessary reprojection. |
proj
|
Projection, default: null | The projection in which to perform the operation. If not specified, the operation will be performed in a spherical coordinate system, and linear distances will be in meters on the sphere. |
