  - ### Methods Summary

    Methods
    Type Params | Return Type | Name and description
    --- | --- | ---
    `` | `protected void` | `assertNotNull(java.lang.Object object, java.lang.String message)`
    `` | `long` | `contentLength()` This implementation returns the underlying File's length.
    `` | `Resource` | `createRelative(java.lang.String relativePath)` This implementation creates a FileSystemResource, applying the given path relative to the path of the underlying file of this resource descriptor.
    `` | `boolean` | `equals(java.lang.Object obj)` This implementation compares the underlying File references.
    `` | `boolean` | `exists()` This implementation returns whether the underlying file exists.
    `` | `java.lang.String` | `getDescription()` This implementation returns a description that includes the absolute path of the file.
    `` | `java.io.File` | `getFile()` This implementation returns the underlying File reference.
    `` | `java.lang.String` | `getFilename()` This implementation returns the name of the file.
    `` | `java.io.InputStream` | `getInputStream()` This implementation opens a FileInputStream for the underlying file.
    `` | `java.io.OutputStream` | `getOutputStream()` This implementation opens a FileOutputStream for the underlying file.

    `` | `int` | `hashCode()` This implementation returns the hash code of the underlying File reference.
    `` | `boolean` | `isReadable()` This implementation checks whether the underlying file is marked as readable (and corresponds to an actual file with content, not to a directory).
