public class Upload
extends AbstractComponent
implements Component.Focusable, LegacyComponent
```
Component for uploading files from client to server.
The visible component consists of a file name input box and a browse button and an upload submit button to start uploading.

The Upload component needs a java.io.OutputStream to write the uploaded data. You need to implement the Upload.Receiver interface and return the output stream in the receiveUpload() method.

You can get an event regarding starting (StartedEvent), progress (ProgressEvent), and finishing (FinishedEvent) of upload by implementing StartedListener, ProgressListener, and FinishedListener, respectively. The FinishedListener is called for both failed and succeeded uploads. If you wish to separate between these two cases, you can use SucceededListener (SucceededEvenet) and FailedListener (FailedEvent).

The upload component does not itself show upload progress, but you can use the ProgressIndicator for providing progress feedback by implementing ProgressListener and updating the indicator in updateProgress().

Setting upload component immediate with setImmediateMode(boolean) initiates the upload as soon as a file is selected, instead of the common pattern of file selection field and upload button.

Note! Because of browser dependent implementations of <input type="file"> element, setting size for Upload component is not supported. For some browsers setting size may work to some extend.

    Sets the Tabulator index of this Focusable component.
    
    Specified by:
    
    setTabIndex in interface Component.Focusable
    
    Parameters:

  - startUpload
```
public void startUpload()
```
    Go into upload state. This is to prevent double uploading on same component. Warning: this is an internal method used by the framework and should not be used by user of the Upload component. Using it results in the Upload component going in wrong state and not working. It is currently public because it is used by another class.
  - interruptUpload
```
public void interruptUpload()
```
    Interrupts the upload currently being received. The interruption will be done by the receiving thread so this method will return immediately and the actual interrupt will happen a bit later.
  - isUploading

public boolean isUploading()
```
  - getBytesRead
```
public long getBytesRead()
```
    Gets read bytes of the file currently being uploaded.

```
public long getUploadSize()
```
    Returns size of file currently being uploaded. Value sane only during upload.
    
    Returns:
    
    size in bytes
  - getButtonCaption
```
public String getButtonCaption()
```
    Returns the string rendered into button that fires uploading.
    
    Returns:
    
    String to be rendered into button that fires uploading
  - getButtonStyleName
```
public String getButtonStyleName()
```
    Returns the style name rendered into button that fires uploading.
    
    Returns:
    
    Style name to be rendered into button that fires uploading
    
    Since:
    
    8.2
  - isButtonCaptionAsHtml
```
public boolean isButtonCaptionAsHtml()
```
    Checks whether the caption of the button that fires uploading is rendered as HTML
    The default is false, i.e. to render that caption as plain text.
    
    Returns:
    
    true if the caption is rendered as HTML, false if rendered as plain text
    
    Since:
    
    8.11
  - setButtonCaption
```
public void setButtonCaption(String buttonCaption)
```
    In addition to the actual file chooser, upload components have button that starts actual upload progress. This method is used to set text in that button.
    In case the button text is set to null, the button is hidden. In this case developer must explicitly initiate the upload process with submitUpload().
    In case the Upload is used in immediate mode using setImmediateMode(boolean), the file chooser (HTML input with type "file") is hidden and only the button with this text is shown.
    
    Note the string given is set as is to the button. HTML formatting is not stripped. Be sure to properly validate your value according to your needs.
    
    Parameters:
    
    buttonCaption - text for upload components button.
  - setButtonStyleName
```
public void setButtonStyleName(String buttonStyleName)
```
    In addition to the actual file chooser, upload components have button that starts actual upload progress. This method is used to set a style name to that button.
    Note: Unlike Button.setStyleName() this method overrides all the styles from the button. If you wish to preserve the default styles, enter the style name as "v-button yourStyleName".
    
    Parameters:
    
    buttonStyleName - style name for upload components button.
    
    Since:
    
    8.2
    
    See Also:
    
    about when the button is shown / hidden.
  - setButtonCaptionAsHtml
```
public void setButtonCaptionAsHtml(boolean buttonCaptionAsHtml)
```
    In addition to the actual file chooser, upload components have button that starts actual upload progress. This method is used to set whether the caption on that button is rendered as HTML.
    If set to true, the caption is rendered in the browser as HTML and the developer is responsible for ensuring no harmful HTML is used. If set to false, the caption is rendered in the browser as plain text.
    The default is false, i.e. to render the caption as plain text.
    
    Parameters:
    
    buttonCaptionAsHtml - true if the caption is rendered as HTML, false if rendered as plain text
    
    Since:
    
    8.11
  - submitUpload
```
public void submitUpload()
```
    Instructs the upload component to send selected file to the server.
    In case developer wants to use this feature, he/she will most probably want to hide the upload component's internal submit button by setting its caption to null with setButtonCaption(String) method.
    Note that the upload runs asynchronously. Developer should use normal upload listeners to track the process of upload. If the file name field is empty, no upload will be triggered.
    Also note that the developer should not remove or modify the upload component in the same user transaction where the upload submit is requested. The upload component can be safely hidden or removed once the upload started event has been fired.
  - markAsDirty
```
public void markAsDirty()
```
    Description copied from interface: ClientConnector
    
    Marks that this connector's state might have changed. When the framework is about to send new data to the client-side, it will run ClientConnector.beforeClientResponse(boolean) followed by ClientConnector.encodeState() for all connectors that are marked as dirty and send any updated state info to the client.
    
    Specified by:
    
    markAsDirty in interface ClientConnector
    
    Specified by:
    
    markAsDirty in interface LegacyComponent

  - getListeners
```
public Collection<?> getListeners(Class<?> eventType)
```
    Description copied from class: AbstractClientConnector
    
    Returns all listeners that are registered for the given event type or one of its subclasses.
    
    Overrides:
    
    getListeners in class AbstractClientConnector
    
    Parameters:
    
    eventType - The type of event to return listeners for.
    
    Returns:
    
    A collection with all registered listeners. Empty if no listeners are found.
  - setImmediateMode
```
public void setImmediateMode(boolean immediateMode)
```
    Sets the immediate mode of the upload.
    If the upload is in immediate mode, the file upload is started immediately after the user has selected the file.
    If the upload is not in immediate mode, after selecting the file the user must click another button to start the upload.
    The default mode of an Upload component is immediate.

    immediateMode - true for immediate mode, false for not
    
    Since:
