Class BufferCapabilities.FlipContents

java.lang.Object
  extended by java.awt.BufferCapabilities.FlipContents
Enclosing class:
BufferCapabilities

public static final class BufferCapabilities.FlipContents
extends Object

A type-safe enumeration of the possible back buffer contents after page-flipping

Since:
1.4

Field Summary
static BufferCapabilities.FlipContents BACKGROUND
          When flip contents are BACKGROUND, the contents of the back buffer are cleared with the background color after flipping.
static BufferCapabilities.FlipContents COPIED
          When flip contents are COPIED, the contents of the back buffer are copied to the front buffer when flipping.
static BufferCapabilities.FlipContents PRIOR
          When flip contents are PRIOR, the contents of the back buffer are the prior contents of the front buffer (a true page flip).
static BufferCapabilities.FlipContents UNDEFINED
          When flip contents are UNDEFINED, the contents of the back buffer are undefined after flipping.
 
Method Summary
 int hashCode()
          Returns a hash code value for the object.
 String toString()
          Returns a string representation of the object.

Method Detail

hashCode

public int hashCode()
Description copied from class: Object
Returns a hash code value for the object. This method is supported for the benefit of hashtables such as those provided by java.util.Hashtable.

The general contract of hashCode is:

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the JavaTM programming language.)

Overrides:
hashCode in class Object
Returns:
a hash code value for this object.
See Also:
Object.equals(java.lang.Object), Hashtable

toString

public String toString()
Description copied from class: Object
Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())
 

Overrides:
toString in class Object
Returns:
a string representation of the object.
