Interface Summary
VariableResolver: This class is used to customize the way the evaluator resolves variable references.

Class Summary
AndOperator: The implementation of the and operator
ArithmeticOperator: This is the superclass for all binary arithmetic operators
ArraySuffix: Represents an operator that obtains a Map entry, an indexed value, a property value, or an indexed property value of an object.
BeanInfoIndexedProperty: This contains the information for one indexed property in a BeanInfo - IndexedPropertyDescriptor, read method, and write method.
BeanInfoManager: Manages the BeanInfo for one class - contains the BeanInfo, and also a mapping from property name to BeanInfoProperty.
BeanInfoProperty: This contains the information for one property in a BeanInfo - PropertyDescriptor, read method, and write method.
BinaryOperator: This is the superclass for all binary operators
BinaryOperatorExpression: An expression representing a binary operator on a value
BooleanLiteral: An expression representing a boolean literal value
Coercions: This class contains the logic for coercing data types before operators are applied to them.
ComplexValue: Represents a dynamic value, which consists of a prefix and an optional set of ValueSuffix elements.
Constants: This contains all of the non-public constants, including messsage strings read from the resource file.
DivideOperator: The implementation of the divide operator
ELEvaluator: This is the main class for evaluating expression Strings.
EmptyOperator: The implementation of the empty operator
EnumeratedMap: This is a Map implementation driven by a data source that only provides an enumeration of keys and a getValue(key) method.
EqualityOperator: This is the superclass for all equality operators (==, !=)
EqualsOperator: The implementation of the equals operator
Evaluator: This is the expression evaluator "adapter" that customizes it for use with the JSP Standard Tag Library.
Expression: The abstract class from which all expression types derive.
ExpressionString: Represents an expression String consisting of a mixture of Strings and Expressions.
FloatingPointLiteral: An expression representing a floating point literal value.
FunctionInvocation: Represents a function call.
GreaterThanOperator: The implementation of the greater than operator
GreaterThanOrEqualsOperator: The implementation of the greater than or equals operator
ImplicitObjects: This class is used to generate the implicit Map and List objects that wrap various elements of the PageContext.
IntegerDivideOperator: The implementation of the integer divide operator
IntegerLiteral: An expression representing an integer literal value.
JSTLVariableResolver: This is the JSTL-specific implementation of VariableResolver.
LessThanOperator: The implementation of the less than operator
LessThanOrEqualsOperator: The implementation of the less than or equals operator
Literal: An expression representing a literal value
Logger: The evaluator may pass an instance of this class to operators and expressions during evaluation.
MinusOperator: The implementation of the minus operator
ModulusOperator: The implementation of the modulus operator
MultiplyOperator: The implementation of the multiply operator
NamedValue: Represents a name that can be used as the first element of a value.
NotEqualsOperator: The implementation of the not equals operator
NotOperator: The implementation of the not operator
NullLiteral: An expression representing a null literal value
OrOperator: The implementation of the or operator
PlusOperator: The implementation of the plus operator
PropertySuffix: Represents an operator that obtains the value of another value's property.
RelationalOperator: This is the superclass for all relational operators (except == or !=)
StringLiteral: An expression representing a String literal value.
UnaryMinusOperator: The implementation of the unary minus operator
UnaryOperator: This is the superclass for all unary operators
UnaryOperatorExpression: An expression representing one or more unary operators on a value
ValueSuffix: Represents an element that can appear as a suffix in a complex value, such as a property or index operator, or a method call (should they ever need to be supported).

Exception Summary
ELException: Represents any of the exception conditions that arise during the operation evaluation of the evaluator.
