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

Method Detail

selectorNames

public Set<SelectorName> selectorNames()

Get the selector symbols to which this operand applies.

Specified by:

selectorNames in interface DynamicOperand

Returns:

the immutable ordered set of non-null selector names used by this operand; never null and never empty

See Also:

DynamicOperand.selectorNames()

operator

public ArithmeticOperator operator()

Get the operator for this binary operand.

Returns:

the operator; never null

left

public DynamicOperand left()

Get the left-hand operand.

Returns:

the left-hand operator; never null

right

public DynamicOperand right()

Get the right-hand operand.

Returns:

the right-hand operator; never null
