}

Constructs an MBeanInfo.

Parameters:

className - The name of the Java class of the MBean described by this MBeanInfo. This value may be any syntactically legal Java class name. It does not have to be a Java class known to the MBean server or to the MBean's ClassLoader. If it is a Java class known to the MBean's ClassLoader, it is recommended but not required that the class's public methods include those that would appear in a Standard MBean implementing the attributes and operations in this MBeanInfo.

description - A human readable description of the MBean (optional).

attributes - The list of exposed attributes of the MBean. This may be null with the same effect as a zero-length array.

constructors - The list of public constructors of the MBean. This may be null with the same effect as a zero-length array.

operations - The list of operations of the MBean. This may be null with the same effect as a zero-length array.

notifications - The list of notifications emitted. This may be null with the same effect as a zero-length array.

Constructs an MBeanInfo.

Parameters:

className - The name of the Java class of the MBean described by this MBeanInfo. This value may be any syntactically legal Java class name. It does not have to be a Java class known to the MBean server or to the MBean's ClassLoader. If it is a Java class known to the MBean's ClassLoader, it is recommended but not required that the class's public methods include those that would appear in a Standard MBean implementing the attributes and operations in this MBeanInfo.

description - A human readable description of the MBean (optional).

attributes - The list of exposed attributes of the MBean. This may be null with the same effect as a zero-length array.

constructors - The list of public constructors of the MBean. This may be null with the same effect as a zero-length array.

operations - The list of operations of the MBean. This may be null with the same effect as a zero-length array.

notifications - The list of notifications emitted. This may be null with the same effect as a zero-length array.

descriptor - The descriptor for the MBean. This may be null which is equivalent to an empty descriptor.

 static boolean arrayGettersSafe(Class<?> subclass,
    Class<?> immutableClass) 
{
        if (subclass == immutableClass)
            return true;
        synchronized (arrayGettersSafeMap) {
            Boolean safe = arrayGettersSafeMap.get(subclass);
            if (safe == null) {
                try {
                    ArrayGettersSafeAction action =
                        new ArrayGettersSafeAction(subclass, immutableClass);
                    safe = AccessController.doPrivileged(action);
                } catch (Exception e) { // e.g. SecurityException
                    /* We don't know, so we assume it isn't.  */
                    safe = false;
                }
                arrayGettersSafeMap.put(subclass, safe);
            }
            return safe;
        }
}

Return true if subclass is known to preserve the immutability of immutableClass. The class immutableClass is a reference class that is known to be immutable. The subclass subclass is considered immutable if it does not override any public method of immutableClass whose name begins with "get". This is obviously not an infallible test for immutability, but it works for the public interfaces of the MBean*Info classes.

 public Object clone() 
{
         try {
             return super.clone() ;
         } catch (CloneNotSupportedException e) {
             // should not happen as this class is cloneable
             return null;
         }
}

Returns a shallow clone of this instance. The clone is obtained by simply calling super.clone(), thus calling the default native shallow cloning mechanism implemented by Object.clone(). No deeper cloning of any internal field is made.

Since this class is immutable, the clone method is chiefly of interest to subclasses.

 public boolean equals(Object o) 
{
        if (o == this)
            return true;
        if (!(o instanceof MBeanInfo))
            return false;
        MBeanInfo p = (MBeanInfo) o;
        if (!isEqual(getClassName(),  p.getClassName()) ||
                !isEqual(getDescription(), p.getDescription()) ||
                !getDescriptor().equals(p.getDescriptor())) {
            return false;
        }
        return
            (Arrays.equals(p.fastGetAttributes(), fastGetAttributes()) &&
             Arrays.equals(p.fastGetOperations(), fastGetOperations()) &&
             Arrays.equals(p.fastGetConstructors(), fastGetConstructors()) &&
             Arrays.equals(p.fastGetNotifications(), fastGetNotifications()));
}

Compare this MBeanInfo to another. Two MBeanInfo objects are equal if and only if they return equal values for #getClassName() , for #getDescription() , and for #getDescriptor() , and the arrays returned by the two objects for #getAttributes() , #getOperations() , #getConstructors() , and #getNotifications() are pairwise equal. Here "equal" means Object#equals(Object) , not identity.

If two MBeanInfo objects return the same values in one of their arrays but in a different order then they are not equal.

 public MBeanAttributeInfo[] getAttributes() 
{
        MBeanAttributeInfo[] as = nonNullAttributes();
        if (as.length == 0)
            return as;
        else
            return as.clone();
}

Returns the list of attributes exposed for management. Each attribute is described by an MBeanAttributeInfo object. The returned array is a shallow copy of the internal array, which means that it is a copy of the internal array of references to the MBeanAttributeInfo objects but that each referenced MBeanAttributeInfo object is not copied.

 public String getClassName() 
{
        return className;
}

Returns the name of the Java class of the MBean described by this MBeanInfo.

 public MBeanConstructorInfo[] getConstructors() 
{
        MBeanConstructorInfo[] cs = nonNullConstructors();
        if (cs.length == 0)
            return cs;
        else
            return cs.clone();
}

Returns the list of the public constructors of the MBean. Each constructor is described by an MBeanConstructorInfo object.

The returned array is a shallow copy of the internal array, which means that it is a copy of the internal array of references to the MBeanConstructorInfo objects but that each referenced MBeanConstructorInfo object is not copied.

The returned list is not necessarily exhaustive. That is, the MBean may have a public constructor that is not in the list. In this case, the MBean server can construct another instance of this MBean's class using that constructor, even though it is not listed here.

 public String getDescription() 
{
        return description;
}

Returns a human readable description of the MBean.

 public Descriptor getDescriptor() 
{
        return (Descriptor) nonNullDescriptor(descriptor).clone();
}

Get the descriptor of this MBeanInfo. Changing the returned value will have no affect on the original descriptor.

 public MBeanNotificationInfo[] getNotifications() 
{
        MBeanNotificationInfo[] ns = nonNullNotifications();
        if (ns.length == 0)
            return ns;
        else
            return ns.clone();
}

Returns the list of the notifications emitted by the MBean. Each notification is described by an MBeanNotificationInfo object. The returned array is a shallow copy of the internal array, which means that it is a copy of the internal array of references to the MBeanNotificationInfo objects but that each referenced MBeanNotificationInfo object is not copied.

 public MBeanOperationInfo[] getOperations() 
{
        MBeanOperationInfo[] os = nonNullOperations();
        if (os.length == 0)
            return os;
        else
            return os.clone();
}

Returns the list of operations of the MBean. Each operation is described by an MBeanOperationInfo object. The returned array is a shallow copy of the internal array, which means that it is a copy of the internal array of references to the MBeanOperationInfo objects but that each referenced MBeanOperationInfo object is not copied.

 public int hashCode() 
{
        /* Since computing the hashCode is quite expensive, we cache it.
           If by some terrible misfortune the computed value is 0, the
           caching won't work and we will recompute it every time.
           We don't bother synchronizing, because, at worst, n different
           threads will compute the same hashCode at the same time.  */
        if (hashCode != 0)
            return hashCode;
        hashCode =
