ResultSetIterator.CustomTypeHandler	An interface to use for custom type handlers
TransformingIterator.TransformerFunction<In,Out>	A functional interface similar to Function, except throwing an exception

Class Summary

Class	Description
BatchingIterator<ObjectType>	An iterator that batches up the inputs into batches of size ‘batchSize’, then returns them in chunks.
CloseableIteratorAdapter<T>	A wrapper class for IIQ’s CloseableIterator that still implements CloseableIterator, but also implement the broader Iterator and AutoClosable interfaces to allow regular Java stuff to interact with it.
ColumnConfig	A wrapper around the various ways of structuring report columns.
ColumnToken	The generic implementation of a colon-separated column token, e.g., ‘col1:blah:stuff’.
FilteringIterator<T>	Implements a Filtering Iterator that will return only items that match the Predicate.
FilteringIterator.DynamicValuePredicate<T>	A predicate that returns true if a DynamicValue or a Script returns a value that maps to Boolean true via Util.otob(Object).
Index<T>	An indexing class for associating items in a list with their index in the list
IndexingIterator<In>	An iterator that keeps track of its index, allowing you to get the current element count.
NullCloseableIterator<T>	An implementation of CloseableIterator that always contains no items.
ResultSetIterator	An adapter that translates a ResultSet to IIQ Reporting’s preferred Iterator<Object[]>.
ResultSetIterator.ColumnOutput	The output of ResultSetIterator.extractColumnValue(ResultSet, String, Integer), containing details about the column used as well as the actual value.
TransformingIterator<In,Out>	A class that applies a transformation function to each item of an Iterator before returning it from Iterator.next().
