Groovy is superset of Java, i.e. any valid Java program is also a valid Groovy program. What it makes much easier than Java is the creation of data structures \u2013 no boilerplate constructors and initialisation and the like. Here are some key resources for learning Groovy:<\/p>\n

Often, you will be looking for some recipes and snippets to get started, and that is exactly what we will provide during this week: We will publish one Groovy Snippet per day. Each of my colleagues has selected their favourite script and will share it with all of you ?.<\/p>\n
Please note that this article assumes you have working knowledge of hale studio and know the terminology<\/a>.<\/p>\n

<\/p>\nMonday's Script: Build Polygons from Lines (Thorsten)<\/h2>\n
This script is my personal favorite. While relatively complex, it shows a lot of useful approaches how to work with geometries in a Groovy script.<\/p>\n
This function was built for creating waterbody
Polygons<\/code> fromLineString<\/code> shore segments. It is executed in the context of a Merge type cell as a Greedy Groovy Script function. It takes aMultiLineString<\/code> geometry with unsorted individualLineStrings<\/code> and builds one to many polygons in aMultiPolygon<\/code> from that input.<\/p>\nThis is the script:<\/p>\n
