java.lang.Object
java.awt.RenderingHints.Key
- Enclosing class:
- RenderingHints
Defines the base type of all keys used along with the
RenderingHints class to control various
algorithm choices in the rendering and imaging pipelines.
Instances of this class are immutable and unique which
means that tests for matches can be made using the
== operator instead of the more expensive
equals() method.-

Key
protected Key(int privatekey) Construct a key using the indicated private key. Each subclass of Key maintains its own unique domain of integer keys. No two objects with the same integer key and of the same specific subclass can be constructed. An exception will be thrown if an attempt is made to construct another object of a given class with the same integer key as a pre-existing instance of that subclass of Key.- Parameters:
privatekey- the specified key

Method Details
-
isCompatibleValue
Returns true if the specified object is a valid value for this Key.- Parameters:
val- theObjectto test for validity- Returns:
trueifvalis valid;falseotherwise.
-
intKey
protected final int intKey()Returns the private integer key that the subclass instantiated this Key with.- Returns:
- the private integer key that the subclass instantiated this Key with.
-
hashCode
public final int hashCode()The hash code for all Key objects will be the same as the system identity code of the object as defined by the System.identityHashCode() method. -
equals
The equals method for all Key objects will return the same result as the equality operator '=='.
