Description

Interface Summary

AbstractIterResultSet.ColumnGetter	A ColumnGetter retrieves a column from an input row based upon its 1-based ordinal.
Iterable	An object is Iterable if it has an Iterable.iterator() method to create an Iterator over its elements.
RestartableIterator	RestartableIterator extends the Iterator interface with a method for restarting to the beginning of the collection.
TupleIter	TupleIter provides an Iterator-like interface for reading tuple data.

Class Summary

AbstractIterResultSet	AbstractIterResultSet provides functionality common to all ResultSet implementations that convert from iterator convention.
AbstractIterResultSet.FieldGetter	A FieldGetter retrieves each public field as a separate column.
AbstractIterResultSet.SingletonColumnGetter	A SingletonColumnGetter retrieves the object itself.
AbstractIterResultSet.SyntheticColumnGetter	A SyntheticColumnGetter retrieves columns from a synthetic object.
AbstractTupleIter	A base class for implementations of TupleIter, with default implementations of some of its methods.
BufferedIterator	BufferedIterator converts a regular iterator into one which implements Iterable (and Enumeration for good measure).
BufferedIterator.Clonerator	Reads from an iterator, duplicating elements into a list as it does so.
BufferedIterator.Test
CalcTupleIter	CalcTupleIter is an abstract base for iterator implementations generated by IterCalcRel .
CompoundIterator	CompoundIterator creates an iterator out of several.
CompoundIterator.Test
CompoundIterator.Test.Box
CompoundIterator.Test.BoxIterator
CompoundParallelTupleIter	CompoundParallelTupleIter creates one TupleIter out of several.
CompoundParallelTupleIter.Test
CompoundTupleIter	CompoundTupleIter creates an iterator out of several iterators.
CompoundTupleIter.Test
CompoundTupleIter.Test.Box
CompoundTupleIter.Test.BoxTupleIter
Dummy	Dummy is the default context for code calling the net.sf.saffron.oj.stmt.OJStatement.execute() method.
EnumerationIterator	EnumerationIterator is an adapter which converts an Enumeration into an Iterator.
ExclusivePipe	A synchronization primitive which allows producer and a consumer to use the same Buffer without treading on each other's feet.
Holder	A set of classes for holding primitive objects.
Holder.int_Holder
Interlock	A synchronization primitive which allows a producer and a consumer to use the same resources without treading on each other's feet.
IteratorResultSet	A IteratorResultSet is an adapter which converts a Iterator into a ResultSet.
NestedLoopCalcTupleIter	NestedLoopCalcTupleIter is a specialization of CalcTupleIter for use in implementing nested loop inner joins over iterators.
QueueIterator	Adapter that exposes a 'push' producer as an Iterator.
QueueIterator.EndOfQueue	Sentinel object.
QueueIterator.WrappedNull	A null masquerading as a real object.
QueueIteratorTest	Test case for QueueIteratorTest.TestingTimeoutQueueIterator and its subclasses ThreadIterator and QueueIteratorTest.TestingTimeoutQueueIterator.
QueueIteratorTest.TestingTimeoutQueueIterator	A TimeoutQueueIterator that exposes its inner QueueIterator for direct reading.
QueueIteratorTest.TickIterator	Iterator which returns an element from an array on a regular basis.
RestartableCollectionIterator	RestartableCollectionIterator implements the RestartableIterator interface in terms of an underlying Collection.
RestartableCollectionTupleIter	RestartableCollectionTupleIter implements the TupleIter interface in terms of an underlying Collection.
RestartableIteratorTupleIter	RestartableIteratorTupleIter adapts an underlying RestartableIterator as a TupleIter.
ResultSetIterator	A ResultSetIterator is an adapter which converts a ResultSet to a Iterator.
ResultSetTupleIter	A ResultSetTupleIter is an adapter which converts a ResultSet to a TupleIter.
Row	When a relational expression obeys the result set calling convention, and does not explicitly specify a row type, the results are object of type Row.
Semaphore	A counting semaphore.
SyntheticObject	SyntheticObject is a base class for all objects built 'on the fly' by the saffron system.
ThreadIterator	ThreadIterator converts 'push' code to 'pull'.
TimeoutQueueIterator	Adapter which allows you to iterate over an Iterator with a timeout.
TimeoutQueueTupleIter	Adapter which allows you to iterate over an TupleIter with a timeout.
TimeoutQueueTupleIter.Fencepost
TimeoutQueueTupleIterTest	Test case for TimeoutQueueTupleIter.
TimeoutQueueTupleIterTest.TickIterator	Iterator which returns an element from an array on a regular basis.
TupleIterResultSet
VarDecl	An array of VarDecls is returned from the dummy() method which is generated to implement a variable declaration, or a list of statements which contain variable declarations.

Enum Summary

TupleIter.NoDataReason

NoDataReason provides a reason why no data was returned by a call to TupleIter.fetchNext().

Exception Summary

AbstractIterResultSet.SqlTimeoutException	Indicates that an operation timed out.
QueueIterator.TimeoutException	Thrown by QueueIterator.hasNext(long) and QueueIterator.next(long) to indicate that operation timed out before rows were available.
TupleIter.TimeoutException	One way to indicate that TupleIter.fetchNext() timed-out.
