## Interface OpenMBeanConstructorInfo

- All Known Implementing Classes:
    OpenMBeanConstructorInfoSupport

      public interface OpenMBeanConstructorInfo

  Describes a constructor of an Open MBean.

  This interface declares the same methods as the class `MBeanConstructorInfo`. A class implementing this interface (typically `OpenMBeanConstructorInfoSupport`) should extend `MBeanConstructorInfo`.

  The `getSignature()` method should return at runtime an array of instances of a subclass of `MBeanParameterInfo` which implements the `OpenMBeanParameterInfo` interface (typically `OpenMBeanParameterInfoSupport`).

  Since:
    1.5

- - ### Method Summary

    Methods
    Modifier and Type | Method and Description
    --- | ---
    `boolean` | `equals(Object obj)` Compares the specified obj parameter with this `OpenMBeanConstructorInfo` instance for equality.
    `String` | `getDescription()` Returns a human readable description of the constructor described by this `OpenMBeanConstructorInfo` instance.
    `String` | `getName()` Returns the name of the constructor described by this `OpenMBeanConstructorInfo` instance.
    `MBeanParameterInfo[]` | `getSignature()` Returns an array of `OpenMBeanParameterInfo` instances describing each parameter in the signature of the constructor described by this `OpenMBeanConstructorInfo` instance.
    `int` | `hashCode()` Returns the hash code value for this `OpenMBeanConstructorInfo` instance.
    `String` | `toString()` Returns a string representation of this `OpenMBeanConstructorInfo` instance.

- - ### Method Detail

    - #### getDescription

          String getDescription()

      Returns a human readable description of the constructor described by this `OpenMBeanConstructorInfo` instance.
      Returns:
        the description.

    - #### getName

          String getName()

      Returns the name of the constructor described by this `OpenMBeanConstructorInfo` instance.
      Returns:
        the name.

    - #### getSignature

          MBeanParameterInfo[] getSignature()

      Returns an array of `OpenMBeanParameterInfo` instances describing each parameter in the signature of the constructor described by this `OpenMBeanConstructorInfo` instance.
      Returns:
        the signature.

    - #### equals

          boolean equals(Object obj)

      Compares the specified obj parameter with this `OpenMBeanConstructorInfo` 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.
      Overrides:
        `equals` in class `Object`
      Parameters:
        `obj` - the object to be compared for equality with this `OpenMBeanConstructorInfo` instance;
      Returns:
        `true` if the specified object is equal to this `OpenMBeanConstructorInfo` instance.
      See Also:
        `Object.hashCode()`, `HashMap`

    - #### hashCode

          int hashCode()

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

      The hash code of an `OpenMBeanConstructorInfo` 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 `OpenMBeanConstructorInfo` 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 `OpenMBeanConstructorInfo` instance
      See Also:
        `Object.equals(java.lang.Object)`, `System.identityHashCode(java.lang.Object)`

    - #### toString

          String toString()

      Returns a string representation of this `OpenMBeanConstructorInfo` instance.

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

      Overrides:
        `toString` in class `Object`
      Returns:
        a string representation of this `OpenMBeanConstructorInfo` instance
