public interface OpenMBeanInfo
Describes an Open MBean: an Open MBean is recognized as such if its {@link javax.management.DynamicMBean#getMBeanInfo() getMBeanInfo()} method returns an instance of a class which implements the {@link OpenMBeanInfo} interface, typically {@link OpenMBeanInfoSupport}.
This interface declares the same methods as the class {@link javax.management.MBeanInfo}. A class implementing this interface (typically {@link OpenMBeanInfoSupport}) should extend {@link javax.management.MBeanInfo}.
The {@link #getAttributes()}, {@link #getOperations()} and {@link #getConstructors()} methods of the implementing class should return at runtime an array of instances of a subclass of {@link MBeanAttributeInfo}, {@link MBeanOperationInfo} or {@link MBeanConstructorInfo} respectively which implement the {@link OpenMBeanAttributeInfo}, {@link OpenMBeanOperationInfo} or {@link OpenMBeanConstructorInfo} interface respectively.

public boolean equals(Object obj)
OpenMBeanInfo
instance for equality.
Returns true if and only if all of the following statements are true:
OpenMBeanInfo
interface,OpenMBeanInfo
interface.
equals
in class Object
obj
- the object to be compared for equality with this OpenMBeanInfo
instance;true
if the specified object is equal to this OpenMBeanInfo
instance.public MBeanAttributeInfo[] getAttributes()
public String getClassName()
public MBeanConstructorInfo[] getConstructors()
public String getDescription()
public MBeanNotificationInfo[] getNotifications()
public MBeanOperationInfo[] getOperations()
public int hashCode()
OpenMBeanInfo
instance.
The hash code of an OpenMBeanInfo
instance is the sum of the hash codes
of all elements of information used in equals
comparisons
(ie: its class name, and its infos on attributes, constructors, operations and notifications,
where the hashCode of each of these arrays is calculated by a call to
new java.util.HashSet(java.util.Arrays.asList(this.getSignature)).hashCode()).
This ensures that t1.equals(t2)
implies that t1.hashCode()==t2.hashCode()
for any two OpenMBeanInfo
instances t1
and t2
,
as required by the general contract of the method
{@link Object#hashCode() Object.hashCode()}.

OpenMBeanInfo
instance.
The string representation consists of the name of this class (ie javax.management.openmbean.OpenMBeanInfo
),
the MBean class name,
and the string representation of infos on attributes, constructors, operations and notifications of the described MBean.
