Method Details

defaultVisit

protected void defaultVisit(IonValue value)
                     throws Exception

Default visitation behavior, called by all visit methods in AbstractValueVisitor. Subclasses should override this unless they override all visit methods.

This implementation always throws UnsupportedOperationException.

Parameters:

value - the value to visit.

Throws:

UnsupportedOperationException - always thrown unless subclass overrides this implementation.

Exception - subclasses can throw this; it will be propagated by the other visit methods.
