• Method Details

  • isReadable

  boolean isReadable()
  Returns true if the attribute described by this OpenMBeanAttributeInfo instance is readable, false otherwise.
  Returns:
  true if the attribute is readable.

  • isWritable

  boolean isWritable()
  Returns true if the attribute described by this OpenMBeanAttributeInfo instance is writable, false otherwise.
  Returns:
  true if the attribute is writable.

  • isIs

  boolean isIs()
  Returns true if the attribute described by this OpenMBeanAttributeInfo instance is accessed through a is_XXX_ getter (applies only to boolean and Boolean values),false otherwise.
  Returns:
  true if the attribute is accessed through is_XXX_.

  • equals

  boolean equals​(Object obj)
  Compares the specified obj parameter with thisOpenMBeanAttributeInfo instance for equality.
  Returns true if and only if all of the following statements are true:
  * obj is non null,
  * obj also implements the OpenMBeanAttributeInfo interface,
  * their names are equal
  * their open types are equal
  * their access properties (isReadable, isWritable and isIs) are equal
  * their default, min, max and legal values are equal.
  This ensures that this equals method works properly for obj parameters which are different implementations of the OpenMBeanAttributeInfo interface.
  Specified by:
  [equals](OpenMBeanParameterInfo.html#equals%28java.lang.Object%29) in interface [OpenMBeanParameterInfo](OpenMBeanParameterInfo.html "interface in javax.management.openmbean")
  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 OpenMBeanAttributeInfo instance;
  Returns:
  true if the specified object is equal to this OpenMBeanAttributeInfo instance.

  Object.hashCode(), HashMap

  • hashCode

  int hashCode()
  Returns the hash code value for this OpenMBeanAttributeInfo instance.
  The hash code of an OpenMBeanAttributeInfo instance is the sum of the hash codes of all elements of information used in equals comparisons (ie: its name, its open type, and its default, min, max and legal values).
  This ensures that t1.equals(t2) implies that t1.hashCode()==t2.hashCode() for any two OpenMBeanAttributeInfo instances t1 and t2, as required by the general contract of the methodObject.hashCode().
  Specified by:
  [hashCode](OpenMBeanParameterInfo.html#hashCode%28%29) in interface [OpenMBeanParameterInfo](OpenMBeanParameterInfo.html "interface in javax.management.openmbean")
  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 OpenMBeanAttributeInfo instance
  See Also:
  Object.equals(java.lang.Object), System.identityHashCode(java.lang.Object)

  • toString

  Returns a string representation of this OpenMBeanAttributeInfo instance.
  The string representation consists of the name of this class (ie javax.management.openmbean.OpenMBeanAttributeInfo), the string representation of the name and open type of the described attribute, and the string representation of its default, min, max and legal values.
  Specified by:
  [toString](OpenMBeanParameterInfo.html#toString%28%29) in interface [OpenMBeanParameterInfo](OpenMBeanParameterInfo.html "interface in javax.management.openmbean")
  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 OpenMBeanAttributeInfo instance
