## Package com.bea.p13n.expression.operator Description

This package provides interfaces and classes for constructing expressions.

This package provides following class of operators to construct an expression. All the operators extend the base class `Operator` and implement either `BinaryOperator` or `UnaryOperator` depending on the type of operator (binary or unary).

- Logical
- Comparative
- Math
- Collection
- String
- Comparative
- Miscellaneous

Some of the operators in Miscellaneous category are If, MethodCall, etc

See Also:
  `LogicalOperator`, `LogicalAnd`, `ComparativeOperator`, `GreaterThan`, `LessThan`, `MathOperator`, `MathAdd`, `Operator`, `BinaryOperator`, `UnaryOperator`, `Expression`, `ProxyExpression`
