Method renamingDecorator

output/java_guava/1.4.18/MoreExecutors.java:817–832

Creates an Executor that renames the Thread threads that its tasks run in. The names are retrieved from the nameSupplier on the thread that is being renamed right before each task is run. The renaming is best effort, if a SecurityManager prevents the renaming then

    final Executor executor, final Supplier<String> nameSupplier)
