Auto-Generated Component Methods
This section provides an overview of noteworthy methods provided in the auto-generated component files. In some cases, the names of the methods vary by language.
serviceFunction()
The core functionality of a component resides in the serviceFunction()
method in C++, the process()
method in Python, and the serviceFunction()
method in Java. The serviceFunction()
is invoked on a recurring basis after start()
is called on the component’s base class.
When serviceFunction
returns NORMAL
, it will immediately loop back. In Java, if objects are created in the serviceFunction
and no blocking calls are made, garbage collection will be deferred until no more heap space is available. Under these conditions, there are likely to be substantial CPU and JVM memory utilization issues.
constructor()
This is the component/device constructor. When this function is invoked, properties of kind property are initialized to their default or overloaded state.
