Class ObjectIdentityWrapper
This class is a thin wrapper around Object
that makes
the methods hashCode()
and equals(Object)
as discriminating as possible.
Object | object - The
Object wrapped by this
ObjectIdentityWrapper .
|
boolean | equals(Object o) - Uses the
== operator to test for equality between
the object wrapped by this ObjectIdentityWrapper and
the object wrapped by the ObjectIdentityWrapper o.
|
int | hashCode() - Uses
System.identityHashCode(Object) to compute a
hash code for the object wrapped by this
ObjectIdentityWrapper .
|
String | toString() - Convert this Object to a human-readable String.

object
public Object object
The Object
wrapped by this
ObjectIdentityWrapper
.
equals
public boolean equals(Object o)
Uses the ==
operator to test for equality between
the object wrapped by this ObjectIdentityWrapper
and
the object wrapped by the ObjectIdentityWrapper
o.
Returns false if o is not a ObjectIdentityWrapper
.
- equals in interface Object
hashCode
public int hashCode()
Uses System.identityHashCode(Object)
to compute a
hash code for the object wrapped by this
ObjectIdentityWrapper
.
- hashCode in interface Object
toString
public String toString()
Convert this Object to a human-readable String.
There are no limits placed on how long this String
should be or what it should contain. We suggest you
make it as intuitive as possible to be able to place
it into
System.out.println()
and such.
It is typical, but not required, to ensure that this method
never completes abruptly with a
RuntimeException
.
This method will be called when performing string
concatenation with this object. If the result is
null
, string concatenation will instead
use
"null"
.
The default implementation returns
getClass().getName() + "@" +
Integer.toHexString(hashCode())
.
- toString in interface Object
- the String representing this Object, which may be null
ObjectIdentityWrapper.java -- Wrapper class used to override equals()
and hashCode() to be as discriminating as possible
