Interface Summary

Interface	Description
Expression	An expression is something that can be executed to compute a result.
ExpressionFunctionManager	This interface is used in conjunction with the FunctionFactory, but provides the functions to add new expressions.
ExpressionParseContext	Passed to the ELParser to help it create Expressions that have dynamic implementations.
FunctionFactory

Class Summary

Class	Description
AbstractExpression
AbstractFunctionFactory
ArithmeticExpression
BasicFunctionFactory	This basic function factory extends AbstractFunctionFactory in order to implement the ExpressionFunctionManager interface, making it mutable.
BitwiseExpression
BitwiseNot	This class allows for the execution of the unary bitwise complement (aka NOT) operator in Expression Language.
BoundPropertyExpression	This is an expression that is bound to a property value in a given PropertyValueSource.
BoundTagExpression
ComparisonExpression
ConstantExpression
ContextDelegateFunctionFactory	Many custom function factories get cached, but when delegating to the factory provided by the context, that shouldn't happen.
DefaultFunctionFactory	Basic function factory that adds all of the common functions that apply to all scopes.
