Parallel processing in Java applications
By default, the correlator operates in a serial manner. If you want, you can implement contexts for parallel processing. You can create contexts only with EPL but you can then use those contexts from your Apama Java code. This section provides information about how to use contexts in Apama Java applications.
For general information about contexts and instructions for creating contexts, see Implementing Parallel Processing in Developing Apama Applications in EPL.
You can find a sample Java application that implements the use of contexts in the samples\java-monitor\context directory of your Apama installation directory.
The topics in this section include:
*Overview of contexts in Java applications
*Using contexts in Java applications
*Using the Context class default constructor
