Class StreamBuilder

java.lang.Object

nce.stream.StreamBuilder

Direct Known Subclasses:

StreamBuilderVapLiq

public class StreamBuilder
extends java.lang.Object

Implementation of a builder design pattern for stream objects. This builder provides methods for the creation of generic streams, resulting from the combination of the general attributes gas, liquid, vapor, pure, mixture, etc... defined in the Phase class. More specific builders can be implemented extending this class, to create, for example, a water stream, a methane stream and so on. Builder is focused on intensive properties only. Extensive properties shall be assigned by the corresponding setter method.
