Method Detail

executeGet

protected org.apache.http.HttpResponse executeGet(HttpEntry entry)
                                           throws IOException

Executes the GET request method for the given URI. Equivalent to getClient().execute(entry.newGet()).

Throws:

IOException

executeHead

protected org.apache.http.HttpResponse executeHead(HttpEntry entry)
                                            throws IOException

Executes the HEAD request method for the given URI. Equivalent to getClient().execute(entry.newHead()).

Throws:

IOException

getClient

protected final org.apache.http.client.HttpClient getClient()

Returns the cached http client obtained by calling newClient().

Returns:

The cached http client obtained by calling newClient().

newClient

protected org.apache.http.client.HttpClient newClient()

Returns a new http client.

The implementation in the class HttpDriver simply returns new DefaultHttpClient(new ThreadSafeClientConnManager()). If you need special configuration, e.g. for authentication or caching, then you should override this method.

Returns:

A new http client.

newController

public FsController<?> newController(FsModel model,
                                     @CheckForNull
                                     FsController<?> parent)

Description copied from class: FsDriver

Returns a new thread-safe file system controller for the mount point of the given file system model and nullable parent file system controller.

When called, you may assert the following precondition:

 assert null == parent
         ? null == model.getParent()
         : parent.getModel().equals(model.getParent())
 

Specified by:

newController in class FsDriver

Parameters:

model - the file system model.

parent - the nullable parent file system controller.

Returns:

A new thread-safe file system controller for the given mount point and nullable parent file system controller.
