## org.eclipse.birt.report.model.api.elements.structures
Class ParamBinding

    java.lang.Object
      org.eclipse.birt.report.model.core.Structure
          org.eclipse.birt.report.model.api.elements.structures.ParamBinding

All Implemented Interfaces:
  java.lang.Cloneable, IStructure, org.eclipse.birt.report.model.core.IPropertySet

    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.

Field Summary
`static java.lang.String` | `EXPRESSION_MEMBER` Name of the parameter binding expression member.
`static java.lang.String` | `PARAM_BINDING_STRUCT` Name of this structure.
`static java.lang.String` | `PARAM_NAME_MEMBER` Name of the parameter name member.

Constructor Summary
`ParamBinding()`

Method Summary
`java.lang.String` | `getExpression()` Returns the binding expression.
`protected java.lang.Object` | `getIntrinsicProperty(java.lang.String propName)`
`java.lang.String` | `getParamName()` Returns the parameter name of this binding.
`java.lang.String` | `getStructName()` Returns the name of the structure definition.
`StructureHandle` | `handle(SimpleValueHandle valueHandle, int index)`
`void` | `setExpression(java.lang.String expression)` Sets the binding expression.
`protected void` | `setIntrinsicProperty(java.lang.String propName, java.lang.Object value)`
`void` | `setParamName(java.lang.String name)` Sets the parameter name of this binding.
`java.util.List` | `validate(org.eclipse.birt.report.model.core.Module module, org.eclipse.birt.report.model.core.DesignElement element)`
