BBjInterpreter

Description

In BBj 25.03 and higher the BBjInterpreter object provides access to selected BBj interpreter functionality through a Java API. This allows Java code to invoke interpreter-level operations such as executing BBj commands, calling BBj programs, and managing interpreter behavior without direct access to the BBj language.

Creation

Obtain a BBjInterpreter object through the following BBjAPI object method:

Return Value	Method
BBjInterpreter	getInterpreter()

Methods of BBjInterpreter

Return Value	Method
List<Object>	call(String program, Object... args)
Object	eval(String cmd)
Future<T>	executeInInterpreterContext(Callable<T> callable)
boolean	isInterpreterContext()
void	processEvents()
void	processPendingEvents()
void	release() release(int exitValue)
void	setErr(Object obj, String method)
void	setEsc(Object obj, String method)
void	waitVerb(double fractionalSeconds)

Remarks

BBjInterpreter methods need to be called from the correct interpreter context, meaning they need to be called from the same thread that created the BBjAPI while the interpreter is still running. They will throw an error if they are called from the wrong context.
