**Inheritance:**
java.lang.Object
```
public class WarningInfo
```

Contains information about a warning that Aspose.Words issued during document loading or saving.

To learn more, visit the [ Programming with Documents ][Programming with Documents] documentation article.

 **Remarks:** 

You do not create instances of this class. Objects of this class are created and passed by Aspose.Words to the [IWarningCallback.warning(com.aspose.words.WarningInfo)](../../com.aspose.words/iwarningcallback/\#warning-com.aspose.words.WarningInfo) method.

 **Examples:** 

Shows how to set the property for finding the closest match for a missing font from the available font sources.

```

 // Open a document that contains text formatted with a font that does not exist in any of our font sources.
 Document doc = new Document(getMyDir() + "Missing font.docx");

 // Assign a callback for handling font substitution warnings.
 WarningInfoCollection warningCollector = new WarningInfoCollection();
 doc.setWarningCallback(warningCollector);

 // Set a default font name and enable font substitution.
 FontSettings fontSettings = new FontSettings();
 fontSettings.getSubstitutionSettings().getDefaultFontSubstitution().setDefaultFontName("Arial");
 fontSettings.getSubstitutionSettings().getFontInfoSubstitution().setEnabled(true);

 // Original font metrics should be used after font substitution.
 doc.getLayoutOptions().setKeepOriginalFontMetrics(true);

 // We will get a font substitution warning if we save a document with a missing font.
 doc.setFontSettings(fontSettings);
 doc.save(getArtifactsDir() + "FontSettings.EnableFontSubstitution.pdf");

 for (WarningInfo info : warningCollector)
 {
     if (info.getWarningType() == WarningType.FONT_SUBSTITUTION)
         System.out.println(info.getDescription());
 }
 
```
