apply

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

Description copied from class: Procedure

Call this Procedure using the explicit-CallContext-convention. The input arguments are (by default) in stack.args; the result is written to ctx.consumer.

Overrides:

apply in class Procedure

Throws:

java.lang.Throwable

run

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

Throws:

java.lang.Throwable

run

public void run()

run

public void run(Consumer out)

runCleanup

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

apply0

public java.lang.Object apply0()
                        throws java.lang.Throwable

Specified by:

apply0 in class Procedure0

Throws:

java.lang.Throwable

getMainPrintValues

public static boolean getMainPrintValues()

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

setMainPrintValues

public static void setMainPrintValues(boolean value)

processArgs
