IOProvider (I/O API and SPI)

java.lang.Object
- org.netbeans.api.io.IOProvider

```
public abstract class IOProvider
extends java.lang.Object
```
A factory for IO tabs shown in the output window. To create a new tab to write to, call e.g. IOProvider.getDefault().getIO("MyTab", false) (pass true if there may be an existing tab with the same name and you want to write to a new tab).
Methods of this class can be called in any thread.

  - getDefault
```
@NonNull
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.
    
    Returns:
    
    The default instance (never null).
  - get
```
@NonNull
public static IOProvider get(@NonNull
                             java.lang.String id)
```
    Gets IOProvider of selected name or delegates to getDefault() if none was found.
    
    Parameters:
    
    id - ID of provider.
    
    Returns:
    
    The instance corresponding to provided name or default instance if not found.
  - getId
```
@NonNull
public abstract java.lang.String getId()
```
    Gets identifier of this provider.
    
    Returns:
    
    Name of this provider.
  - getIO
```
@NonNull
public abstract InputOutput getIO(@NonNull
                                  java.lang.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 localised 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.

public abstract InputOutput getIO(@NonNull
                                  java.lang.String name,
                                  boolean newIO,

                                  org.openide.util.Lookup lookup)
```
    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 localised display name for the tab.
    
    newIO - If true, a new InputOutput is returned, else an existing InputOutput of the same name may be returned.
    
    lookup - Lookup which may contain additional information for various implementations of output window.
    
    Returns:
    
    An InputOutput instance for accessing the new tab.
