Constructor Detail

### MathRint

    public MathRint()

### MathRint

    public MathRint(Object lhs)

Method Detail

### getOperand

    public Object getOperand()

  Description copied from interface: `UnaryOperator`
  Returns unary operand.

  Specified by:
    `getOperand` in interface `UnaryOperator`
  Returns
    An unary 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.
