Class NewInstanceOperatorExpression

java.lang.Object
com.espertech.esper.common.client.soda.ExpressionBase
com.espertech.esper.common.client.soda.NewInstanceOperatorExpression
All Implemented Interfaces:
Expression, 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[] {{...}, {...}}".
