Interface Summary

Interface	Description
AccessPath	AccessPath represents a proposed access path for an Optimizable.
ASTVisitor	A Visitor which handles nodes in Derby's abstract syntax trees.
C_NodeTypes	The purpose of this interface is to hold the constant definitions of the different node type identifiers, for use with NodeFactory.
CodeGeneration	This is a simple interface that houses externally visible statics for code generation.
CompilerContext	CompilerContext stores the parser and type id factory to be used by the compiler.
CostEstimate	A CostEstimate represents the cost of getting a ResultSet, along with the ordering of rows in the ResultSet, and the estimated number of rows in this ResultSet.
ExpressionClassBuilderInterface	This is a simple interface to hide the impl of ExpressionClassBuilder from the protocol side.
JoinStrategy	A JoinStrategy represents a strategy like nested loop, hash join, merge join, etc.
Optimizable	Optimizable provides services for optimizing a table in a query.
OptimizableList	OptimizableList provides services for optimizing a list of Optimizables (tables) in a query.
OptimizablePredicate	OptimizablePredicate provides services for optimizing predicates in a query.
OptimizablePredicateList	OptimizablePredicateList provides services for optimizing a table in a query.
Optimizer	Optimizer provides services for optimizing a query.
OptimizerFactory	This is simply the factory for creating an optimizer.
OptTrace	Interface for optimizer tracing.
Parser	The Parser interface is intended to work with Jack-generated parsers (now JavaCC).
RequiredRowOrdering	This interface provides a representation of the required ordering of rows from a ResultSet.
RowOrdering	This interface provides a representation of the ordering of rows in a ResultSet.
TypeCompiler	This interface defines methods associated with a TypeId that are used by the compiler.
TypeCompilerFactory	Factory interface for the compilation part of datatypes.
Visitable	A Visitable is something that can be visited by a Visitor
VisitableFilter	Filter for qualifying Visitables.
Visitor	A visitor is an object that traverses the querytree and performs some action.

Class Summary

Class	Description
IgnoreFilter	Filter which fails all Visitables.
OptimizerPlan	High level description of a plan for consideration by the Optimizer.
OptimizerPlan.ConglomerateRS
OptimizerPlan.DeadEnd	Generic plan for row sources we don't understand
OptimizerPlan.Join
OptimizerPlan.RowSource<D extends UniqueTupleDescriptor>
OptimizerPlan.TableFunctionRS
ScopeFilter	Filter which passes Visitables only if the compiler is inside a named scope.
TagFilter	Filter which passes Visitables which have been marked with a given tag.
