LogicalMultiOr Class

public final class LogicalMultiOr

    extends LogicalOperator

Implementation of the LogicalMultiOr operator. This operator allows an array of operands to be ORed together. Each operand should either be a Boolean or an Expression which evaluates to a Boolean.
Input 1-N: A Boolean (or Expression returning a Boolean).
Returns: A Boolean( IN(1) || IN(2) || IN(3) etc. ).

public LogicalMultiOr(Object[] orArray)

Method Detail

getParameterSignature() Method

public Class[] getParameterSignature()
Description copied from Expression.getParameterSignature()
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.
