OpenMBeanInfoSupport | public class OpenMBeanInfoSupport extends MBeanInfo implements OpenMBeanInfo,Serializable(Code) | | The OpenMBeanInfoSupport class describes the management information of an open MBean:
it is a subclass of
javax.management.MBeanInfo , and it implements the
OpenMBeanInfo interface.
Note that an open MBean is recognized as such if its getMBeanInfo() method returns an instance of a class
which implements the OpenMBeanInfo interface, typically OpenMBeanInfoSupport.

Constructor Summary | |
public | OpenMBeanInfoSupport(String className, String description, OpenMBeanAttributeInfo[] openAttributes, OpenMBeanConstructorInfo[] openConstructors, OpenMBeanOperationInfo[] openOperations, MBeanNotificationInfo[] notifications) Constructs an OpenMBeanInfoSupport instance,
which describes a class of open MBeans with the specified
className, description, openAttributes,
openConstructors , openOperations and notifications. |
Method Summary | |
public boolean | equals(Object obj) Compares the specified obj parameter with this OpenMBeanInfoSupport instance for equality. | public int | hashCode() Returns the hash code value for this OpenMBeanInfoSupport instance. | public String | toString() Returns a string representation of this OpenMBeanInfoSupport instance. |
OpenMBeanInfoSupport | public OpenMBeanInfoSupport(String className, String description, OpenMBeanAttributeInfo[] openAttributes, OpenMBeanConstructorInfo[] openConstructors, OpenMBeanOperationInfo[] openOperations, MBeanNotificationInfo[] notifications)(Code) | | Constructs an OpenMBeanInfoSupport instance,
which describes a class of open MBeans with the specified
className, description, openAttributes,
openConstructors , openOperations and notifications.
The openAttributes, openConstructors,
openOperations and notifications
array parameters are internally copied, so that subsequent changes
to the arrays referenced by these parameters have no effect on this instance.
Parameters: className - The fully qualified Java class name ofthe open MBean described by this OpenMBeanInfoSupport instance. Parameters: description - A human readable description ofthe open MBean described by this OpenMBeanInfoSupport instance. Parameters: openAttributes - The list of exposed attributes of the described open MBean;Must be an array of instances of a subclass of MBeanAttributeInfo,typically OpenMBeanAttributeInfoSupport. Parameters: openConstructors - The list of exposed public constructors of the described open MBean;Must be an array of instances of a subclass of MBeanConstructorInfo,typically OpenMBeanConstructorInfoSupport. Parameters: openOperations - The list of exposed operations of the described open MBean.Must be an array of instances of a subclass of MBeanOperationInfo,typically OpenMBeanOperationInfoSupport. Parameters: notifications - The list of notifications emitted by the described open MBean. throws: ArrayStoreException - If openAttributes, openConstructors or openOperationsis not an array of instances of a subclass of MBeanAttributeInfo,MBeanConstructorInfo or MBeanOperationInfo respectively. |
equals | public boolean equals(Object obj)(Code) | | Compares the specified obj parameter with this OpenMBeanInfoSupport 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.
Parameters: obj - the object to be compared for equality with this OpenMBeanInfoSupport instance; true if the specified object is equal to this OpenMBeanInfoSupport instance. |
hashCode | public int hashCode()(Code) | | Returns the hash code value for this OpenMBeanInfoSupport instance.
The hash code of an OpenMBeanInfoSupport 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 OpenMBeanInfoSupport instances t1 and t2 ,
as required by the general contract of the method
Object.hashCode .
However, note that another instance of a class implementing the OpenMBeanInfo interface
may be equal to this OpenMBeanInfoSupport instance as defined by
OpenMBeanInfoSupport.equals(java.lang.Object) ,
but may have a different hash code if it is calculated differently.
As OpenMBeanInfoSupport instances are immutable, the hash code for this instance is calculated once,
on the first call to hashCode , and then the same value is returned for subsequent calls.

toString | public String toString()(Code) | | Returns a string representation of this OpenMBeanInfoSupport instance.
The string representation consists of the name of this class (ie javax.management.openmbean.OpenMBeanInfoSupport ),
the MBean class name,
and the string representation of infos on attributes, constructors, operations and notifications of the described MBean.
As OpenMBeanInfoSupport instances are immutable,
the string representation for this instance is calculated once,
on the first call to toString , and then the same value is returned for subsequent calls.
