Class NewInstanceOperatorExpression

java.lang.Object

com.espertech.esper.common.client.soda.ExpressionBase

com.espertech.esper.common.client.soda.NewInstanceOperatorExpression

All Implemented Interfaces:

Expression, java.io.Serializable

public class NewInstanceOperatorExpression
extends ExpressionBase

The "new instance" operator instantiates a host language object.

Set a array dimension value greater zero for new array. If the child node is a single ArrayExpression, the expression is "new array[] {...}". If the child node is not a single ArrayExpression, the expression is "new array[...][...]". For 2-dimensionnal array initialization, put ArrayExpression inside ArrayExpression, i.e. the expression is "new array[] {{...}, {...}}".
