public IonNull clone() throws UnknownSymbolException

Redeclares com.amazon.ion.IonValue.clone.

Doc from com.amazon.ion.IonValue.clone.

Creates a copy of this value and all of its children. The cloned value may use the same shared symbol tables, but it will have an independent local symbol table if necessary. The cloned value will be modifiable regardless of whether this instance isReadOnly().

The cloned value will be created in the context of the same ValueFactory as this instance; if you want a copy using a different factory, then use ValueFactory#clone(IonValue) instead.

Exceptions
UnknownSymbolException:
if any part of this value has unknown text but known Sid for its field name, annotation or symbol.
