findZones
findZones(recursive, nameOrFilterFunction)
Description
Function to find zones in the specified layer. For example, this.parent defines the parent layer of the script module as the layer to be searched in. If recursive is set to true, sublayers will also be searched. The function returns an array with the Zone objects of the found zones. Particular zones can be searched by name or through a filter function. If searching by name, findZones accepts only the Zone objects that match the specified name. The filter function uses the Zone object of each zone as argument. Only those Zone objects that return true for the search criteria defined in the filter function will be accepted by findZones. Without a name or filter function the Zone objects of all zones in the searched layers will be returned.
Available in: Controller, Processor.
