Constructor Detail

AbstractViewIOKit

public AbstractViewIOKit()

Default constructor.

AbstractViewIOKit

public AbstractViewIOKit(URIInputStreamable uriInputStreamable)

URI input stream locator constructor.

Parameters:

uriInputStreamable - The implementation to use for accessing a URI for input, or null if the default implementation should be used.

AbstractViewIOKit

public AbstractViewIOKit(URIOutputStreamable uriOutputStreamable)

URI output stream locator constructor.

Parameters:

uriOutputStreamable - The implementation to use for accessing a URI for output, or null if the default implementation should be used.

AbstractViewIOKit

public AbstractViewIOKit(URIInputStreamable uriInputStreamable,
                         URIOutputStreamable uriOutputStreamable)

Full constructor.

Parameters:

uriInputStreamable - The implementation to use for accessing a URI for input, or null if the default implementation should be used.

uriOutputStreamable - The implementation to use for accessing a URI for output, or null if the default implementation should be used.

Method Detail

load

public void load(ModelView<M> view,
                 java.net.URI uri)
          throws java.io.IOException

Loads data into a view from a given URI.

This version opens a stream and delegates to load(View, InputStream, URI).

Specified by:

load in interface ViewIOKit<M>

Parameters:

view - The view into which the data should be loaded.

uri - The URI that identifies the resource to be loaded.

Throws:

java.io.IOException - Thrown if there is an error reading the data.

save

public void save(ModelView<M> view,
                 java.net.URI uri)
          throws java.io.IOException

Saves a view to a given URI.

If saving is successful and the view is Modifiable, the view's modified status is set to false.

A calling program should first call the view's verify() method to ensure the data is valid and that the model reflects the currently entered data.

This version opens a stream and delegates to save(View, OutputStream).

Specified by:

save in interface ViewIOKit<M>

Parameters:

view - The view the data of which will be saved at the given URI.

uri - The URI at which the view data should be saved.

Throws:

java.io.IOException - Thrown if there is an error writing the data.
