[Java] Class FileSystemResource

    java.lang.Object
      org.codehaus.groovy.grails.io.support.FileSystemResource

All Implemented Interfaces:
  Resource

    public class FileSystemResource
    extends java.lang.Object

Based on Spring FileSystemResource implementation.

Since:
  28.12.2003

Constructor Summary
`FileSystemResource(java.io.File file)` Create a new FileSystemResource from a File handle.
`FileSystemResource(java.lang.String path)` Create a new FileSystemResource from a file path.

Method Summary
`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.
`java.lang.String` | `getPath()` Return the file path for this resource.
`java.net.URI` | `getURI()` This implementation returns a URI for the underlying file.
`java.net.URL` | `getURL()` This implementation returns a URL 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).
`boolean` | `isWritable()` This implementation checks whether the underlying file is marked as writable (and corresponds to an actual file with content, not to a directory).
`long` | `lastModified()`
`java.lang.String` | `toString()`
