BaseExpression	Generic class for an expression with a base.
ClassTypeExpression
CollectionExpression	Used for wrapping collection of values or expressions.
CompoundExpression	Abstract class for expression that have exactly two children, such as and/or and relations.
ConstantExpression	Used for wrapping constant values.
DataExpression	Superclass for all expression that have a context.
DateConstantExpression	INTERNAL: This expression represents a date represented in JDBC escape syntax, for instance, the String: {d '1901-01-01'} can be used to represent a Date and use used only by the JPQL parser.
ExpressionIterator	Used to itterate an expression tree, through inner subclasses.
ExpressionJavaPrinter	Purpose: Expression Java printer.
ExpressionNormalizer	This is used during the normalization process to allow for a single main expression traversal.
ExpressionOperatorConverter	INTERNAL: Used by function operators in deployment xml generation to accomodate custom functions.
ExpressionSQLPrinter	Purpose: Expression SQL printer.
ExtractOperator	Expression operator customization for EXTRACT(<date-time-part> FROM <date-time>).
FieldExpression	Field expressions represent a field of a table.
ForUpdateClause	Purpose:Represents The FOR UPDATE pessimistically locking clause.
ForUpdateOfClause	Purpose:Represents The FOR UPDATE OF fine-grained pessimistically locking clause.
FromAliasExpression	Represents an alias to a item selected by a from clause sub-select.
FromSubSelectExpression	Allow a table expression to be created on a sub-select to define a sub-select in the from clause.
FunctionExpression	Used for expressions that have 0 to n children.
IndexExpression	Index expression may be created by QueryKeyExpression.index() method in case the QueryKeyExpression corresponds to a CollectionMapping with non-null listOrderField.
LiteralExpression	Used for wrapping literal values.
LogicalExpression	Used for logical AND and OR.
ManualQueryKeyExpression	This class represents a "query key" that isn't really there in the descriptors.
MapEntryExpression
NestedTable
ObjectExpression	Superclass for any object type expressions.
OuterJoinExpressionHolder	Holder class storing a QueryKeyExpression representing an outer join plus some data calculated by method appendFromClauseForOuterJoin.
ParameterExpression	Used for parameterized expressions, such as expression defined in mapping queries.
QueryKeyExpression	Represents expression on query keys or mappings.
RelationExpression	Purpose:Used for all relation operators except for between.
SpatialExpressionOperators	INTERNAL: This class produces a number of ExpressionOperators for spatial classes The static methods in this class are used by Oracle9Platform to initialize these operators.

SubSelectExpression	This is used to support subselects.
TableAliasLookup	INTERNAL: Represents the aliased tables an ObjectExpression will be translated to, along with any of its derived TableExpressions.
TableExpression	A TableExpression allows for a raw database table to be referenced in a query.
