## com.bea.p13n.expression.operator.logical
Class LogicalMultiAnd

    java.lang.Object
      com.bea.p13n.expression.internal.ComplexExpressionImpl
          com.bea.p13n.expression.operator.Operator
              com.bea.p13n.expression.operator.logical.LogicalOperator
                  com.bea.p13n.expression.operator.logical.LogicalMultiAnd

All Implemented Interfaces
  Expression, com.bea.p13n.expression.ExpressionEvents, Serializable, Cloneable

    public final class LogicalMultiAnd

extends LogicalOperator

Implementation of the LogicalMultiAnd operator. This operator allows an array of operands to be ANDed 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. ).

Constructor Detail

### LogicalMultiAnd

    public LogicalMultiAnd()

  Constructs an empty operator and operands can be added later by calling addSubExpression() on this.

### LogicalMultiAnd

    public LogicalMultiAnd(Object[] andArray)

  Constructs a LogicalMultiAnd operator by storing the given array of parameters as its operands.

  Parameters
    `andArray` - An `Object` array.

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.
