Constructor Detail

### ConfigurableJasperReportsView

    public ConfigurableJasperReportsView()

Method Detail

### setExporterClass

    public void setExporterClass(Class<? extends net.sf.jasperreports.engine.JRExporter> exporterClass)

  Set the `JRExporter` implementation `Class` to use. Throws `IllegalArgumentException` if the `Class` doesn't implement `JRExporter`. Required setting, as it does not have a default.

### setUseWriter

    public void setUseWriter(boolean useWriter)

  Specifies whether or not the `JRExporter` writes to the `PrintWriter` of the associated with the request (`true`) or whether it writes directly to the `InputStream` of the request (`false`). Default is `true`.

### onInit

    protected void onInit()

  Checks that the `exporterClass` property is specified.

  Overrides:
    `onInit` in class `AbstractJasperReportsView`
  See Also:
    `AbstractJasperReportsView.initApplicationContext()`

### createExporter

    protected net.sf.jasperreports.engine.JRExporter createExporter()

  Returns a new instance of the specified `JRExporter` class.

  Specified by:
    `createExporter` in class `AbstractJasperReportsSingleFormatView`
  See Also:
    `setExporterClass(Class)`, `BeanUtils.instantiateClass(Class)`

### useWriter

    protected boolean useWriter()

  Indicates how the `JRExporter` should render its data.

  Specified by:
    `useWriter` in class `AbstractJasperReportsSingleFormatView`
  See Also:
    `setUseWriter(boolean)`
