Class Overview

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.

Summary

Protected Constructors
RenderingHints.Key(int privatekey)
Construct a key using the indicated private key.
Public Methods
final boolean equals(Object o)
The equals method for all Key objects will return the same result as the equality operator '=='.
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.
abstract boolean isCompatibleValue(Object val)
Returns true if the specified object is a valid value for this Key.
Protected Methods
final int intKey()
Returns the private integer key that the subclass instantiated this Key with.

Protected Constructors

protected RenderingHints.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

Public Methods

public final boolean equals (Object o)

The equals method for all Key objects will return the same result as the equality operator '=='.

Parameters
o the reference object with which to compare.
Returns
  • true if this object is the same as the obj argument; false otherwise.

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.

Returns
  • a hash code value for this object.

public abstract boolean isCompatibleValue (Object val)

Returns true if the specified object is a valid value for this Key.

Parameters
val the Object to test for validity
Returns
  • true if val is valid; false otherwise.

Protected Methods

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.
