Describes an Open MBean: an Open MBean is recognized as such if its 
getMBeanInfo() method returns an instance of a class which implements the OpenMBeanInfo interface, typically OpenMBeanInfoSupport.


This interface declares the same methods as the class MBeanInfo. A class implementing this interface (typically OpenMBeanInfoSupport) should extend MBeanInfo.


The getAttributes(), getOperations() and getConstructors() methods of the implementing class should return at runtime an array of instances of a subclass of MBeanAttributeInfo, MBeanOperationInfo or MBeanConstructorInfo respectively which implement the OpenMBeanAttributeInfo, OpenMBeanOperationInfo or OpenMBeanConstructorInfo interface respectively. 
Since:1.5

Compares the specified obj parameter with this OpenMBeanInfo instance for equality. 
 Returns true if and only if all of the following statements are true: 
    

  • obj is non null,
    • 

  • obj also implements the OpenMBeanInfo interface,
    • 

  • their class names are equal
    • 

  • their infos on attributes, constructors, operations and notifications are equal
    • 

 This ensures that this equals method works properly for obj parameters which are different implementations of the OpenMBeanInfo interface. 
Params:
  • obj –  the object to be compared for equality with this OpenMBeanInfo instance;
Returns: true if the specified object is equal to this OpenMBeanInfo instance.
/**
     * Compares the specified <var>obj</var> parameter with this {@code OpenMBeanInfo} instance for equality.

Returns the hash code value for this 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 Object.hashCode(). 
Returns: the hash code value for this OpenMBeanInfo instance
