UrlConnectionRetrieveFileTransfer

public UrlConnectionRetrieveFileTransfer()

Method Details

getRemoteFileName

public String getRemoteFileName()

Description copied from interface: IIncomingFileTransfer

Obtains the name of the remote file if possible. The name will typically but not necessarily be the same as the leaf part of the path to the remote file.

Specified by:

getRemoteFileName in interface IIncomingFileTransfer

Overrides:

getRemoteFileName in class AbstractRetrieveFileTransfer

Returns:

The name of the remote file or null if no such name can be determined.

connect

protected void connect()
                throws IOException

Throws:

IOException

isConnected

protected boolean isConnected()

setResumeRequestHeaderValues

protected void setResumeRequestHeaderValues()
                                     throws IOException

Throws:

IOException

setRequestHeaderValues

protected void setRequestHeaderValues()
                               throws InvalidFileRangeSpecificationException

Throws:

InvalidFileRangeSpecificationException

getResponseCode

public int getResponseCode()

getResponseHeaderValues

protected void getResponseHeaderValues()
                                throws IOException

Throws:

IOException

getResumeResponseHeaderValues

protected void getResumeResponseHeaderValues()
                                      throws IOException

Throws:

IOException

setupProxy

protected void setupProxy(Proxy proxy2)

Description copied from class: AbstractRetrieveFileTransfer

Setup ECF proxy. Subclasses must override this method to do appropriate proxy setup. This method will be called from within AbstractRetrieveFileTransfer.sendRetrieveRequest(IFileID, IFileTransferListener, Map) and AbstractRetrieveFileTransfer.sendRetrieveRequest(IFileID, IFileRangeSpecification, IFileTransferListener, Map) , prior to the actual call to AbstractRetrieveFileTransfer.openStreams().

Specified by:

setupProxy in class AbstractRetrieveFileTransfer

Parameters:

proxy2 - the ECF proxy to setup

setupAuthentication

protected void setupAuthentication()
                            throws IOException,
UnsupportedCallbackException

Throws:

IOException

UnsupportedCallbackException

setConnectContextForAuthentication

public void setConnectContextForAuthentication(IConnectContext connectContext)

Description copied from interface: IRetrieveFileTransferContainerAdapter

Set connect context for authentication upon subsequent IRetrieveFileTransferContainerAdapter.sendRetrieveRequest(IFileID, IFileTransferListener, Map). This method should be called with a non-null connectContext in order to allow authentication to occur during call to IRetrieveFileTransferContainerAdapter.sendRetrieveRequest(IFileID, IFileTransferListener, Map).

Specified by:

setConnectContextForAuthentication in interface IRetrieveFileTransferContainerAdapter

Overrides:

setConnectContextForAuthentication in class AbstractRetrieveFileTransfer

Parameters:

connectContext - the connect context to use for authenticating during subsequent call to IRetrieveFileTransferContainerAdapter.sendRetrieveRequest(IFileID, IFileTransferListener, Map). If null, then no authentication will be attempted.

openStreams

protected void openStreams()
                    throws IncomingFileTransferException

Description copied from class: AbstractRetrieveFileTransfer

Open incoming and outgoing streams associated with this file transfer. Subclasses must implement this method to open input and output streams. The remoteFileContents and localFileContent must be non-null after successful completion of the implementation of this method.

Specified by:

openStreams in class AbstractRetrieveFileTransfer

Throws:

IncomingFileTransferException - if some problem

hardClose

protected void hardClose()

Overrides:

hardClose in class AbstractRetrieveFileTransfer

doPause

protected boolean doPause()

Description copied from class: AbstractRetrieveFileTransfer

Subclass overridable version of AbstractRetrieveFileTransfer.pause(). Subclasses must provide an implementation of this method to support IFileTransferPausable .

Specified by:

doPause in class AbstractRetrieveFileTransfer

Returns:

true if the pause is successful. false otherwise.

doResume

protected boolean doResume()

Description copied from class: AbstractRetrieveFileTransfer

Subclass overridable version of AbstractRetrieveFileTransfer.resume(). Subclasses must provide an implementation of this method to support IFileTransferPausable.

Specified by:

doResume in class AbstractRetrieveFileTransfer

Returns:

true if the resume is successful. false otherwise.

getAdapter

public <T> T getAdapter(Class<T> adapter)

Specified by:

getAdapter in interface org.eclipse.core.runtime.IAdaptable

Overrides:

getAdapter in class AbstractRetrieveFileTransfer

getConnectTimeout

protected String getConnectTimeout()
