Package com.hexaly.optimizer

Interface HxLambdaFunction

public interface HxLambdaFunction

Lambda function interface. This particular interface is used to instantiate HxOperator.LambdaFunction in Hexaly Optimizer. A lambda function is a particular HxExpression composed of two parts:

• The arguments of the function (which are also HxExpression of type HxOperator.Argument.
• The body of the function. The body is an HxExpression that will be used to evaluate the result of the function. The body can be any HxExpression composed of any operands and operators supported by Hexaly Optimizer.

HxExpression	call(HxExpression[] arguments)	Evaluates and returns the body of the function.

Method Detail

call

HxExpression call(HxExpression[] arguments)

Evaluates and returns the body of the function. This particular method will be called by HxModel.createLambdaFunction(int, HxLambdaFunction) with an array of HxExpression of type HxOperator.Argument. The size of the array will depend on the number of arguments you want for your function. The number of arguments is specified when you call the HxModel.createLambdaFunction(int, HxLambdaFunction). Your implementation must return an HxExpression that will be used as the body of your Hexaly Optimizer function.
