PDFLinks (Nuxeo 2021.53.3 API Documentation)

java.lang.Object
- org.nuxeo.ecm.platform.pdf.PDFLinks

```
public class PDFLinks
extends Object
```
Extract links as list of LinkInfo from a PDF.
In this first version, extracts only the links of type PDActionRemoteGoTo and PDActionLaunch (typically, when a PDF has a relative link to an external PDF).
If the PDF is encrypted, a call to setPassword must be done before any attempt to get the links.
IMPORTANT
Because we can parse the documents several times to get different links, we don't close it after every call (optimization), it is the caller responsibility to explicitly close it to avoid leaks.

Since:
