Returns an array of OpenMBeanAttributeInfo instances describing each attribute in the open MBean described by thisOpenMBeanInfo instance.
Returns the fully qualified Java class name of the open MBean instances this OpenMBeanInfo describes.
Returns an array of OpenMBeanConstructorInfo instances describing each constructor in the open MBean described by thisOpenMBeanInfo instance.
Returns a human readable description of the type of open MBean instances this OpenMBeanInfo describes.
Returns an array of MBeanNotificationInfo instances describing each notification emitted by the open MBean described by this OpenMBeanInfo instance.
Returns an array of OpenMBeanOperationInfo instances describing each operation in the open MBean described by thisOpenMBeanInfo instance.

• Method Details

  • getClassName

  Returns the fully qualified Java class name of the open MBean instances this OpenMBeanInfo describes.
  Returns:
  the class name.

  • getDescription

  Returns a human readable description of the type of open MBean instances this OpenMBeanInfo describes.
  Returns:
  the description.

  • getAttributes

  Returns an array of OpenMBeanAttributeInfo instances describing each attribute in the open MBean described by thisOpenMBeanInfo instance. Each instance in the returned array should actually be a subclass ofMBeanAttributeInfo which implements theOpenMBeanAttributeInfo interface (typically OpenMBeanAttributeInfoSupport).
  Returns:
  the attribute array.

  • getOperations

  Returns an array of OpenMBeanOperationInfo instances describing each operation in the open MBean described by thisOpenMBeanInfo instance. Each instance in the returned array should actually be a subclass ofMBeanOperationInfo which implements theOpenMBeanOperationInfo interface (typically OpenMBeanOperationInfoSupport).
  Returns:
  the operation array.

  • getConstructors

  Returns an array of OpenMBeanConstructorInfo instances describing each constructor in the open MBean described by thisOpenMBeanInfo instance. Each instance in the returned array should actually be a subclass ofMBeanConstructorInfo which implements theOpenMBeanConstructorInfo interface (typically OpenMBeanConstructorInfoSupport).
  Returns:
  the constructor array.

  • getNotifications

  Returns an array of MBeanNotificationInfo instances describing each notification emitted by the open MBean described by this OpenMBeanInfo instance.
  Returns:
  the notification array.

  • equals

  boolean equals​(Object obj)
  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.
  Overrides:
  [equals](../../../../java.base/java/lang/Object.html#equals%28java.lang.Object%29) in class [Object](../../../../java.base/java/lang/Object.html "class in java.lang")
  Parameters:
  obj - the object to be compared for equality with this OpenMBeanInfo instance;
  Returns:
  true if the specified object is equal to this OpenMBeanInfo instance.
  See Also:
  Object.hashCode(), HashMap

  • hashCode

  int hashCode()
  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 tonew 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 methodObject.hashCode().
  Overrides:
  [hashCode](../../../../java.base/java/lang/Object.html#hashCode%28%29) in class [Object](../../../../java.base/java/lang/Object.html "class in java.lang")
  Returns:
  the hash code value for this OpenMBeanInfo instance
  See Also:
  Object.equals(java.lang.Object), System.identityHashCode(java.lang.Object)

  • toString

  Returns a string representation of this 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.
  Overrides:
  [toString](../../../../java.base/java/lang/Object.html#toString%28%29) in class [Object](../../../../java.base/java/lang/Object.html "class in java.lang")
  Returns:
  a string representation of this OpenMBeanInfo instance
