Class ETPContext

java.lang.Object

com.heirloomcomputing.epli.runtime.ETPContext

public class ETPContext
extends java.lang.Object

Provide a linkage between Elastic PL/I and Elastic COBOL when a PL/I program is compiled with -out:transaction or other flags that require it to communicate with the ecobol.jar or etrans.jar runtimes. Separated like this (rather than having EPLI programs use datatypes and invoke methods from COBOL runtimes) allows non-transaction programs to operate without having the COBOL jars on their classpaths. Consists of static methods that set-up or translate between COBOL world and the PLI world. instances of ETPContext are created to hold state
