FeatureDescriptor (Java Platform SE 8 )

java.lang.Object
- java.beans.FeatureDescriptor

Direct Known Subclasses:

BeanDescriptor, EventSetDescriptor, MethodDescriptor, ParameterDescriptor, PropertyDescriptor
```
public class FeatureDescriptor
extends Object
```
The FeatureDescriptor class is the common baseclass for PropertyDescriptor, EventSetDescriptor, and MethodDescriptor, etc.
It supports some common information that can be set and retrieved for any of the introspection descriptors.
In addition it provides an extension mechanism so that arbitrary attribute/value pairs can be associated with a design feature.

    expert - True if this feature is intended for use by experts only.
  - isHidden
```
public boolean isHidden()
```
    The "hidden" flag is used to identify features that are intended only for tool use, and which should not be exposed to humans.
    
    Returns:
    
    True if this feature should be hidden from human users.
  - setHidden
```
public void setHidden(boolean hidden)
```
    The "hidden" flag is used to identify features that are intended only for tool use, and which should not be exposed to humans.

  - getShortDescription
```
public String getShortDescription()
```
    Gets the short description of this feature.
    
    Returns:
    
    A localized short description associated with this property/method/event. This defaults to be the display name.
