TupleEntryIterator
public TupleEntryIterator(Fields fields)
- Constructor TupleEntryIterator creates a new TupleEntryIterator instance.
- Parameters:
fields
- of type Fields
getFields
public Fields getFields()
- Method getFields returns the fields of this TupleEntryIterator object.
- Returns:
- the fields (type Fields) of this TupleEntryIterator object.
getTupleEntry
public TupleEntry getTupleEntry()
- Method getTupleEntry returns the entry of this TupleEntryIterator object.
Since
TupleEntry
and the underlying Tuple
instances are re-used, you must make a copy if you wish
to store the instances in a Collection for later use.
- Returns:
- the entry (type TupleEntry) of this TupleEntryIterator object.
