next	back to summary
public IonType next() Overrides com.amazon.ion.impl.IonReaderTreeSystem.next. Implements com.amazon.ion.IonReader.next. Doc from com.amazon.ion.IonReader.next. Positions this reader on the next sibling after the current value, returning the type of that value. Once so positioned the contents of this value can be accessed with the `*Value()` methods. A sequence of `next()` calls traverses the data at a constant depth, within the same container. Use `stepIn()` to traverse down into any containers, and `stepOut()` to traverse up to the parent container. Returns:IonType the type of the next Ion value (never `IonType#DATAGRAM`), or `null` when there are no more elements at the current depth in the same container. Annotations @Override

hoist	back to summary
public void hoist(Span span) Implements com.amazon.ion.SeekableReader.hoist. Doc from com.amazon.ion.SeekableReader.hoist. Seeks this reader to produce the given span as if its values were at top-level. The caller cannot `stepOut` from the span nor continue reading beyond it. After calling this method, this reader's current span will be empty and positioned just before the first value of the given span; the caller must call `next()` to begin reading values. At the end of the span, the reader will behave as if it's at EOF regardless whether the source has more data beyond the span. Hoisting makes the span's values appear to be at top-level even if they have containers in the source. The depth will be zero, and calls to `getFieldName()` will return null even if the span's original parent was a struct.
