Package com.fluxtion.generator.compiler

Class InprocessSepCompiler

java.lang.Object
com.fluxtion.generator.compiler.InprocessSepCompiler
public class InprocessSepCompiler
extends java.lang.Object
Generates and compiles a SEP for use by a caller in the same process. The compilation is invoked programmatically removing the need to execute the Fluxtion event stream compiler as an external process.

To generate a SEP the caller invokes one of the static compileSep methods. An instance of SEPConfig is passed to the consumer to control the graph construction, such as adding nodes and defining scopes or identifiers. Simple example adding a single node:

sepTestInstance((c) -> c.addNode(new MyHandler(), "handler"), "com.fluxtion.examples.inprocess", "GenNode_1");

Optionally creates an instance of the compiled StaticEventProcessor with or without calling the init method using one of sepInstance(Consumer, String, String, String, String, boolean).

>This is an experimental feature that needs to tested carefully. The class loading for SEP generation was originally designed to be out of process so there may be issues.

      Build a static event processor using the supplied consumer to populate the SEPConfig. Will always build a new processor, supplying a newly created instance of the class to the caller.

      Set the system property fluxtion.cacheDirectory and fluxtion will create the following sub-directories:

      • classes - the compiled classes
      • source - generated source files the classes are compiled from
      • resources - any other resources generated by fluxtion, suchas meta-data
      Parameters:
      name - The name of the generated static event processor
      pkg - The package name of the generated static event processor
      builder - The Consumer that populates the SEPConfig

      Returns an instance of a static event processor to the caller. Will only build a new processor if a class cannot be found on the classpath that matches the fqn name of the processor. Will generate a static event processor using the supplied consumer to populate the SEPConfig if an existing class cannot be found.
