inquireCredentials

public int inquireCredentials(JFrame f,
                              DataServerItem server_item)

Description copied from interface: DataProvider

Some DataProvider implemenations may require additional information (e.g. username and password) typed by users in a login form. As jScope does not make any assumption on this kind of information it is up to the DataProvider implementation to realize such a form (if any). For this reason jScope calls method InquireCredential passing as argument the container JFrame. InquireCredentials may return:
-DataProvider.LOGIN_OK if the DataProvider has been succesfully validated
-DataProvider.LOGIN_ERROR if the DataProvided did not succeed in validation
-DataProvider.LOGIN_CANCEL if the login proess has been aborted by user (usually pressing
a cancel button)
Only in the first case jScope will proceede with the usega of the DataProvider implementation. In the secon case a warning dialog is shown, and in the third case the DataProvider is simply discarded.

Specified by:

inquireCredentials in interface DataProvider

Overrides:

inquireCredentials in class MdsDataProvider

Parameters:

f - The container Frame.

Returns:

The status of the DataProvider specific validation process

setArgument

public void setArgument(String arg)
                 throws IOException

Description copied from interface: DataProvider

As DataProvider implementations are instantiated by jScope by means of the Class.newInstance(), no arguments can be passed to the constructor method. If an additional argument is required for the proper initialization of the DataProvider implementation (e.g. the ip address for the MdsDataProvider), the argument, defined in the server_n.argument item of the property file is passed through method SetArgument called by jScope just after the DataProvider instantiation.

Specified by:

setArgument in interface DataProvider

Overrides:

setArgument in class MdsDataProvider

Parameters:

arg - The argument passed to the DataProvider implementation.

Throws:

IOException

SetCompression

public void SetCompression(boolean state)

Overrides:

SetCompression in class MdsDataProvider

SupportsCompression

public boolean SupportsCompression()

Overrides:

SupportsCompression in class MdsDataProvider

update

public void update(String exp,
                   long s)

Description copied from interface: DataProvider

Method Update is called by jScope to notify the experiment name and the shot number. Update can be called several time by jScope for the same DataProvider implementation in the case user changes either the experiment name or the shot number.

Specified by:

update in interface DataProvider

Overrides:

update in class MdsDataProvider

Parameters:

exp - The experiment name
