Class Overview
Resource
implementation for java.net.URL
locators.
Obviously supports resolution as URL, and also as File in case of
the "file:" protocol.
Summary
Public Methods |
Resource
|
createRelative(String relativePath)
This implementation creates a UrlResource, applying the given path
relative to the path of the underlying URL of this resource descriptor.
|
boolean
|
equals(Object obj)
This implementation compares the underlying URL references.
|
String
|
getDescription()
This implementation returns a description that includes the URL.
|
File
|
getFile()
This implementation returns a File reference for the underlying URL/URI,
provided that it refers to a file in the file system.
|
String
|
getFilename()
This implementation returns the name of the file that this URL refers to.
|
InputStream
|
getInputStream()
This implementation opens an InputStream for the given URL.
|
URI
|
getURI()
This implementation returns the underlying URI directly,
if possible.
|
URL
|
getURL()
This implementation returns the underlying URL reference.
|

Inherited Methods |
From class
org.springframework.core.io.AbstractFileResolvingResource
long
|
contentLength()
This implementation checks the timestamp of the underlying File,
if available.
|
boolean
|
exists()
This implementation checks whether a File can be opened,
falling back to whether an InputStream can be opened.
|
File
|
getFile(URI uri)
This implementation returns a File reference for the underlying class path
resource, provided that it refers to a file in the file system.
|
File
|
getFile()
This implementation returns a File reference for the underlying class path
resource, provided that it refers to a file in the file system.
|
File
|
getFileForLastModifiedCheck()
This implementation determines the underlying File
(or jar file, in case of a resource in a jar/zip).
|
boolean
|
isReadable()
This implementation always returns true .
|
long
|
lastModified()
This implementation checks the timestamp of the underlying File,
if available.
|
|
From class
org.springframework.core.io.AbstractResource
long
|
contentLength()
This implementation checks the timestamp of the underlying File,
if available.
|
Resource
|
createRelative(String relativePath)
This implementation throws a FileNotFoundException, assuming
that relative resources cannot be created for this resource.
|
boolean
|
equals(Object obj)
This implementation compares description strings.
|
boolean
|
exists()
This implementation checks whether a File can be opened,
falling back to whether an InputStream can be opened.
|
File
|
getFile()
This implementation throws a FileNotFoundException, assuming
that the resource cannot be resolved to an absolute file path.
|
File
|
getFileForLastModifiedCheck()
Determine the File to use for timestamp checking.
|
String
|
getFilename()
This implementation always throws IllegalStateException,
assuming that the resource does not have a filename.
|
URI
|
getURI()
This implementation builds a URI based on the URL returned
by getURL() .
|
URL
|
getURL()
This implementation throws a FileNotFoundException, assuming
that the resource cannot be resolved to a URL.
|
int
|
hashCode()
This implementation returns the description's hash code.
|
boolean
|
isOpen()
This implementation always returns false .
|
boolean
|
isReadable()
This implementation always returns true .
|
long
|
lastModified()
This implementation checks the timestamp of the underlying File,
if available.
|
String
|
toString()
This implementation returns the description of this resource.

Public Constructors
public
UrlResource
(URL url)
Create a new UrlResource.
public
UrlResource
(URI uri)
Create a new UrlResource.
public

(String path)
Create a new UrlResource.
Public Methods
public

createRelative
(String relativePath)
This implementation creates a UrlResource, applying the given path
relative to the path of the underlying URL of this resource descriptor.
Parameters
relativePath
| the relative path (relative to this resource) |
Returns
- the resource handle for the relative resource
public

This implementation compares the underlying URL references.
public
String
getDescription
()
This implementation returns a description that includes the URL.
public
File
getFile
()
This implementation returns a File reference for the underlying URL/URI,
provided that it refers to a file in the file system.
public

if possible.
public
URL
getURL
()
This implementation returns the underlying URL reference.
public
int
