Examples of javax.management.AttributeList.asList()

javax.management.AttributeList.asList()
Return a view of this list as a {@code List}. Changes to the returned value are reflected by changes to the original {@code AttributeList} and vice versa. @return a {@code List} whose contentsreflect the contents of this {@code AttributeList}.
If this method has ever been called on a given {@code AttributeList} instance, a subsequent attempt to addan object to that instance which is not an {@code Attribute}will fail with a {@code IllegalArgumentException}. For compatibility reasons, an {@code AttributeList} on which this method has neverbeen called does allow objects other than {@code Attribute}s to be added.
@throws IllegalArgumentException if this {@code AttributeList} containsan element that is not an {@code Attribute}. @since 1.6
