Method Details
- run
  
  boolean run(String suggestedFilename)
  
  This signal is emitted after response is received to decide a destination for the download using webkit_download_set_destination(). If this signal is not handled, the file will be downloaded to UserDirectory.DIRECTORY_DOWNLOAD directory using suggestedFilename.
  Since 2.40, you may handle this signal asynchronously by returning true without calling webkit_download_set_destination(). This indicates intent to eventually call webkit_download_set_destination(). In this case, the download will not proceed until the destination is set or cancelled with webkit_download_cancel().
- upcall
  
  default int upcall(MemorySegment sourceDownload, MemorySegment suggestedFilename)
  
  The upcall method is called from native code. The parameters are marshaled and run(java.lang.String) is executed.
- toCallback
  
  default MemorySegment toCallback(Arena arena)
  
  Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment) method.
