Method Details

call

Object call(Context context,
 Object... args)

Override with varargs for external Java client convenience. Callers can use: callable.call(ctx, arg1, arg2)

isExternal

default boolean isExternal()

apply

default Object apply(Object t)

Specified by:

apply in interface Function<Object,Object>

test

default boolean test(Object t)

Specified by:

test in interface Predicate<Object>

accept

default void accept(Object t)

Specified by:

accept in interface Consumer<Object>

get

default Object get()

Specified by:

get in interface Supplier<Object>

run

default void run()

Specified by:

run in interface Runnable

isConstructable

default boolean isConstructable()

Whether this callable can be invoked with new. Default: false — only things that explicitly opt in (user-defined non-arrow functions, JsFunction subclasses, builtin constructor singletons, and the JsConstructor marker for Java-bridge types) report true. Used by the interpreter's construct path to throw a TypeError on new <non-constructor>(...) per spec.
