public class VfsResource
VFS based Resource
implementation.
VirtualFile
Constructor Summary | |
---|---|
VfsResource(org.jboss.virtual.VirtualFile file)
|
Method Summary | |
---|---|
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. |
String |
getDescription()
Return a description for this resource, to be used for error output when working with the resource. |
File |
getFile()
This implementation throws a FileNotFoundException, assuming that the resource cannot be resolved to an absolute file path. |
String |
getFilename()
This implementation always throws IllegalStateException, assuming that the resource does not carry a filename. |
InputStream |
getInputStream()
Return an InputStream . |
URI |
getURI()
This implementation builds a URI based on the URL returned by AbstractResource.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 |
isReadable()
This implementation always returns true . |
long |
lastModified()
This implementation checks the timestamp of the underlying File, if available. |

It is expected that each call creates a fresh stream.
This requirement is particularly important when you consider an API such
as JavaMail, which needs to be able to read the stream multiple times when
creating mail attachments. For such a use case, it is required
that each getInputStream()
call returns a fresh stream.
