ClipperPool

clipper.ClipperPool (Class)

Object pooling manager for Clipper2.

Use trackObjects() before clipper operations and recycleObjects() after to reuse allocated objects and reduce GC pressure.

Example:

ClipperPool.trackObjects();
var result = Clipper.inflatePaths(paths, 10, JoinType.Miter, EndType.Polygon);
// Copy needed data from result
ClipperPool.recycleObjects();

Static Members

trackObjects(): Void

Start tracking all created objects for later recycling. Call this before performing clipper operations.

recycleObjects(): Void

Recycle all tracked objects back to their pools. Call this after you've copied the needed data from clipper results. Objects become invalid after this call.

clearPools(): Void

Clear all pools and tracking state. Useful for testing or when you want to release pooled memory.
