Constructor Detail

IOProvider

protected IOProvider()

Subclass constructor.

Method Detail

getDefault

public static IOProvider getDefault()

Get the default I/O provider.

Normally this is taken from Lookup.getDefault() but if there is no instance in lookup, a fallback instance is created which just uses the standard system I/O streams. This is useful for unit tests and perhaps for standalone usage of various libraries.

Assuming you want to ensure that a real output window implementation is actually installed and enabled, you must require the token org.openide.windows.IOProvider from the module calling this method.

Returns:

the default instance (never null)

---

getIO

public abstract InputOutput getIO(String name,
                                  boolean newIO)

Get a named instance of InputOutput, which represents an output tab in the output window. Streams for reading/writing can be accessed via getters on the returned instance.

Parameters:

name - A localized display name for the tab

newIO - if true, a new InputOutput is returned, else an existing InputOutput of the same name may be returned

Returns:

an InputOutput instance for accessing the new tab

See Also:

InputOutput

getIO

public InputOutput getIO(String name,
                         Action[] additionalActions)

Gets a named instance of InputOutput with additional actions displayed in the toolbar. Streams for reading/writing can be accessed via getters on the returned instance. Additional actions are displayed on the output's toolbar.

Parameters:

name - A localized display name for the tab

additionalActions - array of actions that are added to the toolbar, Can be empty array, but not null. The number of actions should not exceed 5 and each should have the Action.SMALL_ICON property defined.

Returns:

an InputOutput instance for accessing the new tab

Since:

1.6
Note: The method is non-abstract for backward compatibility reasons only. If you are extending IOProvider and implementing its abstract classes, you are encouraged to override this method as well. The default implementation falls back to the getIO(name, newIO) method, ignoring the actions passed.

See Also:

InputOutput

---

getStdOut

public abstract OutputWriter getStdOut()

Support writing to the Output Window on the main tab or a similar output device.

Returns:

a writer for the standard NetBeans output area
