Class RenderingHints.Key

Constructor Detail

• RenderingHints.Key

  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

Method Detail

• isCompatibleValue

  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.

• 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.

  Overrides:

  hashCode in class Object

  Returns:

  a hash code value for this object.

  See Also:

  Object.equals(java.lang.Object), System.identityHashCode(java.lang.Object)

• equals

  public final boolean equals(Object o)

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

  Overrides:

  equals in class Object

  Parameters:

  o - the reference object with which to compare.

  Returns:

  true if this object is the same as the obj argument; false otherwise.
