Method Summary

Modifier and Type	Method	Description
`Method`	`getMethod()`	Gets the method that this MethodDescriptor encapsulates.

Methods declared in class FeatureDescriptor

attributeNames, getDisplayName, getName, getShortDescription, getValue, isExpert, isHidden, isPreferred, setDisplayName, setExpert, setHidden, setName, setPreferred, setShortDescription, setValue, toString

Modifier and Type	Method	Description
`Enumeration<String>`	`attributeNames()`	Gets an enumeration of the locale-independent names of this feature.
`String`	`getDisplayName()`	Gets the localized display name of this feature.
`String`	`getName()`	Gets the programmatic name of this feature.
`String`	`getShortDescription()`	Gets the short description of this feature.
`Object`	`getValue(String attributeName)`	Retrieve a named attribute with this feature.
`boolean`	`isExpert()`	The "expert" flag is used to distinguish between those features that are intended for expert users from those that are intended for normal users.
`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.
`boolean`	`isPreferred()`	The "preferred" flag is used to identify features that are particularly important for presenting to humans.
`void`	`setDisplayName(String displayName)`	Sets the localized display name of this feature.
`void`	`setExpert(boolean expert)`	The "expert" flag is used to distinguish between features that are intended for expert users from those that are intended for normal users.
`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.
`void`	`setName(String name)`	Sets the programmatic name of this feature.
`void`	`setPreferred(boolean preferred)`	The "preferred" flag is used to identify features that are particularly important for presenting to humans.
`void`	`setShortDescription(String text)`	You can associate a short descriptive string with a feature.
`void`	`setValue(String attributeName, Object value)`	Associate a named attribute with this feature.
`String`	`toString()`	Returns a string representation of the object.

Methods declared in class Object

clone, equals, finalize, getClass, hashCode, notify, notifyAll, wait, wait, wait

Modifier and Type	Method	Description
`protected Object`	`clone()`	Creates and returns a copy of this object.
`boolean`	`equals(Object obj)`	Indicates whether some other object is "equal to" this one.
`protected void`	`finalize()`	Deprecated, for removal: This API element is subject to removal in a future version. Finalization is deprecated and subject to removal in a future release.
`final Class<?>`	`getClass()`	Returns the runtime class of this `Object`.
`int`	`hashCode()`	Returns a hash code value for this object.
`final void`	`notify()`	Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()`	Wakes up all threads that are waiting on this object's monitor.
`final void`	`wait()`	Causes the current thread to wait until it is awakened, typically by being notified or interrupted.
`final void`	`wait(long timeoutMillis)`	Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis, int nanos)`	Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
