Uses of NullableTuple in org.apache.pig.data

Fields in org.apache.pig.data with type parameters of type NullableTuple

Modifier and Type	Field and Description
protected java.util.Iterator<NullableTuple>	ReadOnceBag.tupIter

Constructor parameters in org.apache.pig.data with type arguments of type NullableTuple

Constructor and Description
ReadOnceBag(Packager pkgr, java.util.Iterator<NullableTuple> tupIter, PigNullableWritable keyWritable) This constructor creates a bag out of an existing iterator of tuples by taking ownership of the iterator and NOT copying the elements of the iterator.
