public abstract class AbstractJasperReportsSingleFormatView
extends AbstractJasperReportsView
```
Extends AbstractJasperReportsView to provide basic rendering logic for views that use a fixed format, e.g. always PDF or always HTML.
Subclasses need to implement two template methods: createExporter to create a JasperReports exporter for a specific output format, and useWriter to determine whether to write text or binary content.
This class is compatible with classic JasperReports releases back until 2.x. As a consequence, it keeps using the JRExporter API which got deprecated as of JasperReports 5.5.2 (early 2014).
从以下版本开始:
1.1.5

`protected abstract net.sf.jasperreports.engine.JRExporter`	`createExporter()`	Create a JasperReports exporter for a specific output format, which will be used to render the report to the HTTP response.
`protected boolean`	`generatesDownloadContent()`	Return whether this view generates download content (typically binary content like PDF or Excel files).
`protected void`	`renderReport(net.sf.jasperreports.engine.JasperPrint populatedReport, Map<String,Object> model, HttpServletResponse response)`	Perform rendering for a single Jasper Reports exporter, that is, for a pre-defined output format.
`protected void`	`renderReportUsingOutputStream(net.sf.jasperreports.engine.JRExporter exporter, net.sf.jasperreports.engine.JasperPrint populatedReport, HttpServletResponse response)`	We need to write binary output to the response OutputStream.
`protected void`	`renderReportUsingWriter(net.sf.jasperreports.engine.JRExporter exporter, net.sf.jasperreports.engine.JasperPrint populatedReport, HttpServletResponse response)`	We need to write text to the response Writer.
`protected abstract boolean`	`useWriter()`	Return whether to use a `java.io.Writer` to write text content to the HTTP response.

    Return whether this view generates download content (typically binary content like PDF or Excel files).
    The default implementation returns false. Subclasses are encouraged to return true here if they know that they are generating download content that requires temporary caching on the client side, typically via the response OutputStream.
    覆盖:
    generatesDownloadContent 在类中 AbstractView

    We need to write text to the response Writer.

    response - the HTTP response the report should be rendered to

protected abstract net.sf.jasperreports.engine.JRExporter createExporter()
```
    Create a JasperReports exporter for a specific output format, which will be used to render the report to the HTTP response.
    The useWriter method determines whether the output will be written as text or as binary content.
    另请参阅:
    useWriter()
  - useWriter
```
protected abstract boolean useWriter()
```
    Return whether to use a java.io.Writer to write text content to the HTTP response. Else, a java.io.OutputStream will be used, to write binary content to the response.
