设置保存超时

设置保存超时

Aspose.CAD for Java API 允许您在保存时设置超时。这在保存过程需要很多时间或占用大量内存的情况下可能会很有用。为此，API提供了 InterruptionTokenSource 类。InterruptionTokenSource 类提供了一个用于中断长时间操作的令牌。

示例代码

以下代码片段演示了 InterruptionTokenSource 类的使用。

// For complete examples and data files, please go to https://github.com/aspose-cad/Aspose.CAD-for-Java
final String SourceDir = Utils.getDataDir_DWGDrawings();
final String OutputDir = Utils.getDataDir_Output();
final InterruptionTokenSource source = new com.aspose.cad.InterruptionTokenSource();
try {
    final CadImage cadImageBig = (CadImage)Image.load(SourceDir + "Drawing11.dwg");
    try {
        CadRasterizationOptions rasterizationOptionsBig = new CadRasterizationOptions();
        rasterizationOptionsBig.setPageWidth(cadImageBig.getSize().getWidth() / 2);
        rasterizationOptionsBig.setPageHeight(cadImageBig.getSize().getHeight() / 2);

        final PdfOptions CADfBig = new PdfOptions();
        CADfBig.setVectorRasterizationOptions(rasterizationOptionsBig);
        CADfBig.setInterruptionToken(source.getToken());

        java.lang.Thread thread = new java.lang.Thread(new Runnable() {
            @Override
            public void run() {
                try {
                    cadImageBig.save(OutputDir + "PutTimeoutOnSave_out.pdf", CADfBig);
                } catch (Throwable th) {
                    System.out.println("interrupted !!!");
                }
            }
        });

        thread.start();
        TimeUnit.SECONDS.sleep(3);
        source.interrupt();
        thread.join();
    } finally {
        cadImageBig.dispose();
    }
} finally {
    source.dispose();
}
