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`.

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`), and of the name and signature of the described constructor.

  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 `Object`
  Returns:
    a string representation of this `OpenMBeanConstructorInfoSupport` instance
