streams framework is a Java implementation of a simple stream processing
environment by Christian Bockermann and Hendrik Blom at TU Dortmund University. It aims at providing a clean and easy-to-use Java-based platform to process streaming data.
The core module of the
streams library is a thin API layer of interfaces and
classes that reflect a high-level view of streaming processes. This API serves
as a basis for implementing custom processors and providing services with the
Figure 1 shows the components of the
streams library. The binding glue element
is a thin API layer that attaches to a runtime provided as a separate module or
can embedded into existing code.
Process Design with JavaBeans
streams library promotes simple software design patterns such as JavaBean
conventions and dependency injection to allow for a quick setup of streaming
processes using simple XML files.
As shown in Figure 2, the idea of the
streams library is to provide a simple
runtime environment that lets users define streaming processes in XML files,
with a close relation to the implementing Java classes.
Based on the conventions and patterns used, components of the
streams library are simple Java classes. Following the basic design
patterns of the
streams library allows for quickly adding custom
classes to the streaming processes without much trouble.
