Interface Summary

EnumeratedValues.Value	A Value represents a member of an enumerated type.
MethodCallTestCase.Dispatcher	A class implementing Dispatcher calls a method from within its own security context.
Walkable	Objects which can be tree-walked by Walker (@see Walker).

Class Summary

BarfingInvocationHandler	A class derived from BarfingInvocationHandler handles a method call by looking for a method in itself with identical parameters.
BinaryHeap	A BinaryHeap is a heap implementation of a priority queue.
BinaryHeap.BinaryHeapTestCase
ClassCollector	ClassCollector walks over an expression tree, calling Expression.getType(openjava.mop.Environment) and Expression.getRowType(openjava.mop.Environment) on each node, and forming a set of distinct types.
DelegatingInvocationHandler	A class derived from DelegatingInvocationHandler handles a method call by looking for a method in itself with identical parameters.
EnumeratedValues	EnumeratedValues is a helper class for declaring a set of symbolic constants which have names, ordinals, and possibly descriptions.
EnumeratedValues.BasicValue	BasicValue is an obvious implementation of EnumeratedValues.Value.
Graph	A Graph is a collection of directed arcs between nodes, and supports various graph-theoretic operations.
Graph.Arc	An Arc is a directed link between two nodes.
Graph.GraphTest
MethodCallTestCase	A MethodCallTestCase is a TestCase which invokes a method on an object.
MultiMap	Map which contains more than one value per key.
MultiMap.ValueList	Holder class, ensures that user's values are never interpreted as multiple values.
RelEnvironment	RelEnvironment defines the set of variables available to a relational expression.
RelVisitor	A RelVisitor is a Visitor role in the Visitor pattern and visits Rel objects as the role of Element.
SaffronProperties	SaffronProperties provides an environment for debugging information, et cetera, used by saffron.
SaffronResource	todo:
SaffronSchemaExpander	Replaces references to the virtual members of Schema expressions.
SaffronValidator	SaffronValidator makes sure that an expression is valid.
SqlToOpenjavaConverter	A SqlToOpenjavaConverter converts a tree of SqlNodes a ParseTree tree.
SqlToOpenjavaConverter.SchemaCatalogReader	A SchemaCatalogReader looks up catalog information from a saffron schema object.
SqlToOpenjavaConverter.TestContext
UnboundVariableCollector
Util	Miscellaneous utility functions.
Util.RelHolder
Util.UtilTestCase
Util.VariableSetVisitor
Util.VariableUsedVisitor
Walker	Walks over a tree, returning nodes in prefix order.
Walker.Region
