layersupport + freezable

[timelyportfolio]

Thanks so much for all your work on this. Is there any way to use layersupport and freezable together/simultaneously?

Hi,

Thank you for your message.

Indeed it looks like the naming collision on _originalOnAdd prevents the simultaneous integration of both plugins.

By using a workaround to prevent this naming collision, all seems the work correctly:

// Modify _originalOnAdd before LayerSupport kicks in, in order to prevent naming collision.
L.MarkerClusterGroup.include({
  // Original onAdd is already stored in _originalOnAdd and replaced in onAdd by Freezable plugin.
  _originalOnAddFreezable: L.MarkerClusterGroup.prototype._originalOnAdd,

  onAdd: function(map) {
    var frozenZoom = this._zoom;

    // Use the new name for the original onAdd.
    this._originalOnAddFreezable(map);

    // Rest of method is unchanged compared to Freezable plugin.
    if (this._frozen) {

      // Restore the specified frozenZoom if necessary.
      if (frozenZoom >= 0 && frozenZoom !== this._zoom) {
        // Undo clusters and markers addition to this._featureGroup.
        this._featureGroup.clearLayers();

        this._zoom = frozenZoom;

        this.addLayers([]);
      }

      // Replace the callbacks on zoomend and moveend events.
      map.off('zoomend', this._zoomEnd, this);
      map.off('moveend', this._moveEnd, this);
      map.on('zoomend moveend', this._viewChangeEndNotClustering, this);
    }
  }
});
