java.lang.Objectjavax.management.openmbean.OpenType<T>
T - the Java type that instances described by this type must
have. For example, SimpleType.INTEGER is a SimpleType<Integer> which is a subclass of OpenType<Integer>,
meaning that an attribute, parameter, or return value that is described
as a SimpleType.INTEGER must have Java type
Integer.public abstract class OpenType<T>
The OpenType class is the parent abstract class of all classes which describe the actual open type
of open data values.
An open type is defined by:

throws OpenDataException
OpenType instance (actually a subclass instance as OpenType is abstract),
checking for the validity of the given parameters.
The validity constraints are described below for each parameter.
className - The fully qualified Java class name of the open data values this open type describes.
The valid Java class names allowed for open data values are listed in
ALLOWED_CLASSNAMES_LIST.
A multidimensional array of any one of these classes
or their corresponding primitive types is also an allowed class,
in which case the class name follows the rules defined by the method
getName() of java.lang.Class.
For example, a 3-dimensional array of Strings has for class name
"[[[Ljava.lang.String;" (without the quotes).
typeName - The name given to the open type this instance represents; cannot be a null or empty string.
description - The human readable description of the open type this instance represents;
cannot be a null or empty string.
IllegalArgumentException - if className, typeName or description
is a null or empty string

ALLOWED_CLASSNAMES_LIST.
A multidimensional array of any one of these classes or their
corresponding primitive types is also an allowed class,
in which case the class name follows the rules defined by the method
getName() of java.lang.Class.
For example, a 3-dimensional array of Strings has for class name
"[[[Ljava.lang.String;" (without the quotes),
a 3-dimensional array of Integers has for class name
"[[[Ljava.lang.Integer;" (without the quotes),
and a 3-dimensional array of int has for class name
"[[[I" (without the quotes)

OpenType instance.
public String getDescription()
OpenType instance.
public boolean isArray()
true if the open data values this open
type describes are arrays, false otherwise.
public abstract boolean isValue(Object obj)
obj - the object to be tested for validity.
true if obj is a value for this
open type, false otherwise.public abstract boolean equals(Object obj)
obj parameter with this
open type instance for equality.
equals in class Objectobj - the object to compare to.

Hashtablepublic abstract int hashCode()
Objectjava.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.)
