PrefixedObjectValueSource

java.lang.Object
- org.codehaus.plexus.interpolation.AbstractDelegatingValueSource
- - org.codehaus.plexus.interpolation.PrefixedObjectValueSource

All Implemented Interfaces:

QueryEnabledValueSource, ValueSource
```
public class PrefixedObjectValueSource
extends AbstractDelegatingValueSource
implements QueryEnabledValueSource
```
Wraps an arbitrary object with an ObjectBasedValueSource instance, then wraps that source with a PrefixedValueSourceWrapper instance, to which this class delegates all of its calls.
