Constructor Detail

ArithmeticOperand

public ArithmeticOperand(DynamicOperand left,
                         ArithmeticOperator operator,
                         DynamicOperand right)

Create a arithmetic dynamic operand that operates upon the supplied operand(s).

Parameters:

left - the left-hand-side operand

operator - the arithmetic operator; may not be null

right - the right-hand-side operand

Throws:

IllegalArgumentException - if any of the arguments is null
