java.lang.Object java.awt.BufferCapabilities.FlipContents
public static final class BufferCapabilities.FlipContents
A type-safe enumeration of the possible back buffer contents after page-flipping
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. |

public int hashCode()
Object
java.util.Hashtable
.
The general contract of hashCode
is:
hashCode
method on each of
the two objects must produce the same integer result.
Object.equals(java.lang.Object)
method, then calling the hashCode method on each of the
two objects must produce distinct integer results. However, the
programmer should be aware that producing distinct integer results
for unequal objects may improve the performance of hashtables.
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.)

Object.equals(java.lang.Object)
,
Hashtable
public String toString()
Object
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())
