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

This package provides interfaces and classes for constructing a collections related expression.

All the operators in this package extend the base class `CollectionOperator` and implement either `BinaryOperator` or `UnaryOperator` depending on the type of operator (binary or unary), but the concrete multi-operand operator doesn't implement any of these interfaces.

This package provides following operators to construct the collections related expression.

- CollectionContains
- CollectionContainsAll
