Constructor Detail
HttpFileObject
protected HttpFileObject(FileName name, HttpFileSystem fileSystem)(Code)




Method Detail
doDetach
protected void doDetach() throws Exception(Code)
Detaches this file object from its file resource.



doGetContentSize
protected long doGetContentSize() throws Exception(Code)
Returns the size of the file content (in bytes).



doGetInputStream
protected InputStream doGetInputStream() throws Exception(Code)
Creates an input stream to read the file content from. Is only called if HttpFileObject.doGetType returns FileType.FILE .

It is guaranteed that there are no open output streams for this file when this method is called.

The returned stream does not have to be buffered.




doGetLastModifiedTime
protected long doGetLastModifiedTime() throws Exception(Code)
Returns the last modified time of this file.

This implementation throws an exception.




doGetRandomAccessContent
protected RandomAccessContent doGetRandomAccessContent(RandomAccessMode mode) throws Exception(Code)



doGetType
protected FileType doGetType() throws Exception(Code)
Determines the type of this file. Must not return null. The return value of this method is cached, so the implementation can be expensive.



doListChildren
protected String[] doListChildren() throws Exception(Code)
Lists the children of this file.



encodePath
protected String encodePath(String decodedPath) throws URIException(Code)



getFileContentInfoFactory
protected FileContentInfoFactory getFileContentInfoFactory()(Code)



getHeadMethod
HeadMethod getHeadMethod()(Code)



setupMethod
void setupMethod(HttpMethod method) throws FileSystemException, URIException(Code)
Prepares a Method object.
