Java compact3 javax.management.openmbean Interface OpenMBeanParameterInfo（JDK8）

Method Detail

• getDescription

  String getDescription()

  Returns a human readable description of the parameter described by this OpenMBeanParameterInfo instance.

  Returns:

  the description.

• getName

  String getName()

  Returns the name of the parameter described by this OpenMBeanParameterInfo instance.

  Returns:

  the name.

• getOpenType

  OpenType<?> getOpenType()

  Returns the open type of the values of the parameter described by this OpenMBeanParameterInfo instance.

  Returns:

  the open type.

• getDefaultValue

  Object getDefaultValue()

  Returns the default value for this parameter, if it has one, or null otherwise.

  Returns:

  the default value.

• getLegalValues

  Set<?> getLegalValues()

  Returns the set of legal values for this parameter, if it has one, or null otherwise.

  Returns:

  the set of legal values.

• getMinValue

  Comparable<?> getMinValue()

  Returns the minimal value for this parameter, if it has one, or null otherwise.

  Returns:

  the minimum value.

• getMaxValue

  Comparable<?> getMaxValue()

  Returns the maximal value for this parameter, if it has one, or null otherwise.

  Returns:

  the maximum value.

• hasDefaultValue

  boolean hasDefaultValue()

  Returns true if this parameter has a specified default value, or false otherwise.

  Returns:

  true if there is a default value.

• hasLegalValues

  boolean hasLegalValues()

  Returns true if this parameter has a specified set of legal values, or false otherwise.

  Returns:

  true if there is a set of legal values.

• hasMinValue

  boolean hasMinValue()

  Returns true if this parameter has a specified minimal value, or false otherwise.

  Returns:

  true if there is a minimum value.

• hasMaxValue

  boolean hasMaxValue()

  Returns true if this parameter has a specified maximal value, or false otherwise.

  Returns:

  true if there is a maximum value.

• isValue

  boolean isValue(Object obj)

  Tests whether obj is a valid value for the parameter described by this OpenMBeanParameterInfo instance.

  Parameters:

  obj - the object to be tested.

  Returns:

  true if obj is a valid value for the parameter described by this OpenMBeanParameterInfo instance, false otherwise.

• equals

  boolean equals(Object obj)

  Compares the specified obj parameter with this OpenMBeanParameterInfo instance for equality.

  Returns true if and only if all of the following statements are true:

  • obj is non null,
  • obj also implements the OpenMBeanParameterInfo interface,
  • their names are equal
  • their open types 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 OpenMBeanParameterInfo interface.
   

  Overrides:

  equals in class Object

  Parameters:

  obj - the object to be compared for equality with this OpenMBeanParameterInfo instance;

  Returns:

  true if the specified object is equal to this OpenMBeanParameterInfo instance.

  Object.hashCode(), HashMap

• hashCode

  int hashCode()

  Returns the hash code value for this OpenMBeanParameterInfo instance.

  The hash code of an OpenMBeanParameterInfo 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 OpenMBeanParameterInfo instances t1 and t2, as required by the general contract of the method Object.hashCode().

  Overrides:

  hashCode in class Object

  Returns:

  the hash code value for this OpenMBeanParameterInfo instance

  See Also:

  Object.equals(java.lang.Object), System.identityHashCode(java.lang.Object)

• toString

  String toString()

  Returns a string representation of this OpenMBeanParameterInfo instance.

  The string representation consists of the name of this class (ie javax.management.openmbean.OpenMBeanParameterInfo), the string representation of the name and open type of the described parameter, and the string representation of its default, min, max and legal values.

  Overrides:

  toString in class Object

  Returns:

  a string representation of this OpenMBeanParameterInfo instance
