public class ParamBinding
extends org.eclipse.birt.report.model.core.Structure

This class presents the parameter binding that bind data set input parameter to expression by position. Order of these bindings must match the order of parameter markers ("?"") in the statement. Each parameter binding has the following properties:

Parameter Name
a parameter bing has a required parameter name to bind.
Expression
associated an expression with a named input parameter.
