Static Method Calls
There are two types of static method call, standalone static method calls and functional static method calls. (Method chainings are a special type of static method call.)
The following is an obsolete variant of the standalone call:
7.31 | 7.40 | 7.54
The static method call described here is not to be confused with the call of static methods. A static method call is the static specification of an instance method or a static method. In addition, there is the dynamic method call, for which the methods are specified dynamically.
