public class CollectionContainsAll

extends CollectionOperator

A class used to represent a CollectionContainsAll operator. This class operates on two Collections. The evaluation of this should return true if the first Collection contains the second Collection, otherwise return false.

Method Detail

getParameterSignature

public Class[] getParameterSignature()

Description copied from interface: Expression

Returns the parameter signature for this Expression. Because the sub-expressions within the Expression are typically arguments or operands, some type validation is performed by examining the class types of the sub-expressions against the Expression's parameter signature.
The tests that are performed are:
1. The number of sub-expressions must equals the number of parameter entries.
2. The class type of any sub-expression (or the result of evaluating the sub-expresssion) must equal the class type of the corresponding parameter entry.
3. Any null parameter entries are ignored and are considered optional sub-expressions.

Returns:

the Class array containing the parameter signature.
