All Implemented Interfaces:

OperatorIfc

@InfixOperator(precedence=40,
               leftAssociative=false)
public class InfixPowerOfOperator
extends AbstractOperator

Power of operator, calculates the power of right operand of left operand. The precedence is read from the configuration during parsing.

Method Detail

evaluate

public EvaluationValue evaluate(Expression expression,
                                Token operatorToken,
                                EvaluationValue... operands)
                         throws EvaluationException

Description copied from interface: OperatorIfc

Performs the operator logic and returns an evaluation result.

Parameters:

expression - The expression, where this function is executed. Can be used to access the expression configuration.

operatorToken - The operator token from the parsed expression.

operands - The operands, one for prefix and postfix operators, two for infix operators.

Returns:

The evaluation result in form of a EvaluationValue.

Throws:

EvaluationException - In case there were problems during evaluation.

getPrecedence

public int getPrecedence(ExpressionConfiguration configuration)

Description copied from interface: OperatorIfc

Called during parsing, can be implemented to return a customized precedence.

Specified by:

getPrecedence in interface OperatorIfc

Overrides:

getPrecedence in class AbstractOperator

Parameters:

configuration - The expression configuration.

Returns:

The default precedence from the operator annotation, or a customized value.
