Method Detail

checkRunDone

public boolean checkRunDone(boolean value)

Description copied from interface: RunnableModule

Check if run has been invoked.

Specified by:

checkRunDone in interface RunnableModule

Parameters:

value - - should be true - probably pointless.

run

public void run(CallContext ctx)
         throws java.lang.Throwable

Specified by:

run in interface RunnableModule

Throws:

java.lang.Throwable

run

public void run()

runToVoid

public static void runToVoid(RunnableModule mod)

run

public void run(Consumer out)

run

public static void run(RunnableModule mod,
                       Consumer out)

runCleanup

public static void runCleanup(CallContext ctx,
                              java.lang.Throwable th,
                              Consumer save)

getMainPrintValues

public static boolean getMainPrintValues()

True if runAsMain should print values (in top-level expressions).

setMainPrintValues

public static void setMainPrintValues(boolean value)

exitIncrement

public static void exitIncrement()

See exitDecrement.

exitDecrement

public static void exitDecrement()

Work around an AWT bug, where AWT threads are non-daemon. Thus if you start up AWT, the JVM will wait for the AWT to finish, even if there are no other non-daemon threads. So call exitIncrement() each time a Freme is created, and call exitDecrement() when a Frame is closed.

runAsMain

public final void runAsMain()

This is invoked by main when ModuleBody is compiled with --main.

runAsMain

public static void runAsMain(RunnableModule module)

This is invoked by main when ModuleBody is compiled with --main.
