Constructor Detail

### LogicalOr

    public LogicalOr()

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

### LogicalOr

    public LogicalOr(Object lhs,
                     Object rhs)

  Constructs equals operator by storing the given parameters as operands of this.

  Parameters
    `lhs` - The left hand side operand of this.
    `rhs` - The right hand side operand of this.

Method Detail

### getLeftHandSide

    public Object getLeftHandSide()

  Description copied from interface: `BinaryOperator`
  Returns left hand side operand of this binary operator.

  Specified by:
    `getLeftHandSide` in interface `BinaryOperator`
  Returns
    The left hand side operand.

### getRightHandSide

    public Object getRightHandSide()

  Description copied from interface: `BinaryOperator`
  Returns right hand side operand of this binary operator.

  Specified by:
    `getRightHandSide` in interface `BinaryOperator`
  Returns
    The left hand side operand.

### 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.

  Specified by:
    `getParameterSignature` in interface `Expression`
  Returns
    the Class array containing the parameter signature.
