Detailed Description

One of the functions of collections is to serve as a repository for intermediate results. In this role, a collection is a helper class. An example is the construction of an MgLineString geometry. From the perspective of construction, this geometry is a set of coordinates. The sequence of construction is:

1. create a coordinate
2. add coordinate to coordinate collection
3. do 1 and 2 until all coordinates created
4. create the line string using coordinate collection

See Geometry Collections for the list of collections used in the construction of geometries.
