Class FileUrlResource

java.lang.Object
nl.basjes.parse.useragent.utils.springframework.core.io.AbstractResource
nl.basjes.parse.useragent.utils.springframework.core.io.AbstractFileResolvingResource

All Implemented Interfaces:
InputStreamSource, Resource
public class FileUrlResource extends UrlResource implements Resource
Subclass of {link UrlResource} which assumes file resolution, to the degree of implementing the {link WritableResource} interface for it. This resource variant also caches resolved {link File} handles from {link #getFile()}.

This is the class resolved by {link DefaultResourceLoader} for a "file:..." URL location, allowing a downcast to {link WritableResource} for it.

Alternatively, for direct construction from a {link java.io.File} handle or NIO {link java.nio.file.Path}, consider using {link FileSystemResource}.

  • Constructor Details

    • FileUrlResource

      public FileUrlResource(URL url)
      Create a new FileUrlResource based on the given URL object.

      Note that this does not enforce "file" as URL protocol. If a protocol is known to be resolvable to a file, it is acceptable for this purpose.

      Parameters:
      url - a URL see ResourceUtils#isFileURL(URL) see #getFile()
