Constructor Detail

### OpenMBeanConstructorInfoSupport

    public OpenMBeanConstructorInfoSupport(String name,
                                           String description,
                                           OpenMBeanParameterInfo[] signature)

  Constructs an `OpenMBeanConstructorInfoSupport` instance, which describes the constructor of a class of open MBeans with the specified `name`, `description` and `signature`.

  The `signature` array parameter is internally copied, so that subsequent changes to the array referenced by `signature` have no effect on this instance.

  Parameters:
    `name` - cannot be a null or empty string.
    `description` - cannot be a null or empty string.
    `signature` - can be null or empty if there are no parameters to describe.
  Throws:
    `IllegalArgumentException` - if `name` or `description` are null or empty string.
    `ArrayStoreException` - If `signature` is not an array of instances of a subclass of `MBeanParameterInfo`.

### OpenMBeanConstructorInfoSupport

    public OpenMBeanConstructorInfoSupport(String name,
                                           String description,
                                           OpenMBeanParameterInfo[] signature,
                                           Descriptor descriptor)

  Constructs an `OpenMBeanConstructorInfoSupport` instance, which describes the constructor of a class of open MBeans with the specified `name`, `description`, `signature`, and `descriptor`.

  The `signature` array parameter is internally copied, so that subsequent changes to the array referenced by `signature` have no effect on this instance.

  Parameters:
    `name` - cannot be a null or empty string.
    `description` - cannot be a null or empty string.
    `signature` - can be null or empty if there are no parameters to describe.
    `descriptor` - The descriptor for the constructor. This may be null which is equivalent to an empty descriptor.
  Throws:
    `IllegalArgumentException` - if `name` or `description` are null or empty string.
    `ArrayStoreException` - If `signature` is not an array of instances of a subclass of `MBeanParameterInfo`.
  Since:
    1.6

Method Detail

### equals

    public boolean equals(Object obj)

  Compares the specified `obj` parameter with this `OpenMBeanConstructorInfoSupport` instance for equality.

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

  - `obj` is non null,
  - `obj` also implements the `OpenMBeanConstructorInfo` interface,
  - their names are equal
  - their signatures are equal.
  This ensures that this `equals` method works properly for `obj` parameters which are different implementations of the `OpenMBeanConstructorInfo` interface.

  Specified by:
    `equals` in interface `OpenMBeanConstructorInfo`
  Overrides:
    `equals` in class `MBeanConstructorInfo`
  Parameters:
    `obj` - the object to be compared for equality with this `OpenMBeanConstructorInfoSupport` instance;
  Returns:
    `true` if the specified object is equal to this `OpenMBeanConstructorInfoSupport` instance.
  See Also:
    `Object.hashCode()`, `Hashtable`

### hashCode

    public int hashCode()

  Returns the hash code value for this `OpenMBeanConstructorInfoSupport` instance.

  The hash code of an `OpenMBeanConstructorInfoSupport` instance is the sum of the hash codes of all elements of information used in `equals` comparisons (ie: its name and signature, where the signature hashCode is calculated by a call to `java.util.Arrays.asList(this.getSignature).hashCode()`).

  This ensures that `t1.equals(t2)` implies that `t1.hashCode()==t2.hashCode()` for any two `OpenMBeanConstructorInfoSupport` 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 `OpenMBeanConstructorInfo` interface may be equal to this `OpenMBeanConstructorInfoSupport` instance as defined by `equals(java.lang.Object)`, but may have a different hash code if it is calculated differently.

  As `OpenMBeanConstructorInfoSupport` 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.

  Specified by:
    `hashCode` in interface `OpenMBeanConstructorInfo`
  Overrides:
    `hashCode` in class `MBeanConstructorInfo`
  Returns:
    the hash code value for this `OpenMBeanConstructorInfoSupport` instance
  See Also:
    `Object.equals(java.lang.Object)`, `Hashtable`

### toString

    public String toString()

  Returns a string representation of this `OpenMBeanConstructorInfoSupport` instance.

  The string representation consists of the name of this class (ie `javax.management.openmbean.OpenMBeanConstructorInfoSupport`), the name and signature of the described constructor and the string representation of its descriptor.

  As `OpenMBeanConstructorInfoSupport` 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.

  Specified by:
    `toString` in interface `OpenMBeanConstructorInfo`
  Overrides:
    `toString` in class `MBeanConstructorInfo`
  Returns:
    a string representation of this `OpenMBeanConstructorInfoSupport` instance
