Package cascading.tuple

Interface Summary

Comparison<T>	The Comparison interface allows specific underlying type mechanisms to additionally return relevant Comparator implementations when required internally.
Hasher<V>	The Hasher allows a Comparator implementation to also be delegated to during hashCode generation during grouping partitioning.
StreamComparator<T extends InputStream>	The StreamComparator interface allows for two InputStream instances to be compared, typically bit-wise.

Class Summary

Fields	Class Fields represents the field names in a Tuple.
Tuple	A Tuple represents a set of values.
TupleEntry	Class TupleEntry allows a Tuple instance and its declaring Fields instance to be used as a single object.
TupleEntryChainIterator
TupleEntryCollector	Interface TupleEntryCollector is used to allow BaseOperation instances to emit result Tuple values.
TupleEntryIterator	Class TupleEntryIterator provides an efficient Iterator for returning TupleEntry elements in an underlying Tuple collection.
TupleEntrySchemeCollector<Config,Output>	Class TupleEntrySchemeCollector is a helper class for wrapping a Scheme instance, calling Scheme.sink(cascading.flow.FlowProcess, cascading.scheme.SinkCall) on every call to TupleEntrySchemeCollector.add(TupleEntry) or TupleEntrySchemeCollector.add(Tuple).
TupleEntrySchemeIterator<Config,Input>	Class TupleEntrySchemeIterator is a helper class for wrapping a Scheme instance, calling Scheme.source(cascading.flow.FlowProcess, cascading.scheme.SourceCall) on every call to TupleEntrySchemeIterator.next().
Tuples	Class Tuples is a helper class providing common methods to manipulate Tuple and TupleEntry instances.

Exception Summary

FieldsResolverException	Class FieldsResolverException is thrown when selectorFields cannot select from the sourceFields.
TupleException	Class TupleException is thrown by the Tuple, Fields and TupleEntry classes.
