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 | TupleEntryChainIterator chains the given Iterators into a single Iterator. |
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. |
