## Class ModelMBeanConstructorInfo

- java.lang.Object
- - javax.management.MBeanFeatureInfo
  - - javax.management.MBeanConstructorInfo
    - - javax.management.modelmbean.ModelMBeanConstructorInfo

- All Implemented Interfaces:
    Serializable, Cloneable, DescriptorAccess, DescriptorRead

      public class ModelMBeanConstructorInfo
      extends MBeanConstructorInfo
      implements DescriptorAccess

  The ModelMBeanConstructorInfo object describes a constructor of the ModelMBean. It is a subclass of MBeanConstructorInfo with the addition of an associated Descriptor and an implementation of the DescriptorAccess interface.

  The fields in the descriptor are defined, but not limited to, the following. Note that when the Type in this table is Number, a String that is the decimal representation of a Long can also be used.

  Name | Type | Meaning
  --- | --- | ---
  name | String | Constructor name.
  descriptorType | String | Must be "operation".
  role | String | Must be "constructor".
  displayName | String | Human readable name of constructor.
  visibility | Number | 1-4 where 1: always visible 4: rarely visible.
  presentationString | String | XML formatted string to describe how to present operation

  The `persistPolicy` and `currencyTimeLimit` fields are meaningless for constructors, but are not considered invalid.

  The default descriptor will have the `name`, `descriptorType`, `displayName` and `role` fields.

  The serialVersionUID of this class is `3862947819818064362L`.

    - #### ModelMBeanConstructorInfo

          public ModelMBeanConstructorInfo(String description,
                                   Constructor<?> constructorMethod)

      Constructs a ModelMBeanConstructorInfo object with a default descriptor. The `Descriptor` of the constructed object will include fields contributed by any annotations on the `Constructor` object that contain the `DescriptorKey` meta-annotation.
      Parameters:
        `description` - A human readable description of the constructor.
        `constructorMethod` - The java.lang.reflect.Constructor object describing the MBean constructor.

    - #### ModelMBeanConstructorInfo

          public ModelMBeanConstructorInfo(String description,
                                   Constructor<?> constructorMethod,
                                   Descriptor descriptor)

      Constructs a ModelMBeanConstructorInfo object. The `Descriptor` of the constructed object will include fields contributed by any annotations on the `Constructor` object that contain the `DescriptorKey` meta-annotation.
      Parameters:
        `description` - A human readable description of the constructor.
        `constructorMethod` - The java.lang.reflect.Constructor object describing the ModelMBean constructor.
        `descriptor` - An instance of Descriptor containing the appropriate metadata for this instance of the ModelMBeanConstructorInfo. If it is null, then a default descriptor will be created. If the descriptor does not contain the field "displayName" this field is added in the descriptor with its default value.
      Throws:
        `RuntimeOperationsException` - Wraps an IllegalArgumentException. The descriptor is invalid, or descriptor field "name" is not equal to name parameter, or descriptor field "descriptorType" is not equal to "operation" or descriptor field "role" is present but not equal to "constructor".

    - #### ModelMBeanConstructorInfo

          public ModelMBeanConstructorInfo(String name,
                                   String description,
                                   MBeanParameterInfo[] signature)

      Constructs a ModelMBeanConstructorInfo object with a default descriptor.
      Parameters:
        `name` - The name of the constructor.
        `description` - A human readable description of the constructor.
        `signature` - MBeanParameterInfo object array describing the parameters(arguments) of the constructor.

    - #### ModelMBeanConstructorInfo

          public ModelMBeanConstructorInfo(String name,
                                   String description,
                                   MBeanParameterInfo[] signature,
                                   Descriptor descriptor)

      Constructs a ModelMBeanConstructorInfo object.
      Parameters:
        `name` - The name of the constructor.
        `description` - A human readable description of the constructor.
        `signature` - MBeanParameterInfo objects describing the parameters(arguments) of the constructor.
        `descriptor` - An instance of Descriptor containing the appropriate metadata for this instance of the MBeanConstructorInfo. If it is null then a default descriptor will be created. If the descriptor does not contain the field "displayName" this field is added in the descriptor with its default value.
      Throws:
        `RuntimeOperationsException` - Wraps an IllegalArgumentException. The descriptor is invalid, or descriptor field "name" is not equal to name parameter, or descriptor field "descriptorType" is not equal to "operation" or descriptor field "role" is present but not equal to "constructor".

  - ### Method Detail

    - #### clone

          public Object clone()

      Creates and returns a new ModelMBeanConstructorInfo which is a duplicate of this ModelMBeanConstructorInfo.
      Overrides:
        `clone` in class `MBeanConstructorInfo`
      Returns:
        a clone of this instance.
      See Also:
        `Cloneable`

    - #### getDescriptor

          public Descriptor getDescriptor()

      Returns a copy of the associated Descriptor.
      Specified by:
        `getDescriptor` in interface `DescriptorRead`
      Overrides:
        `getDescriptor` in class `MBeanFeatureInfo`
      Returns:
        Descriptor associated with the ModelMBeanConstructorInfo object.
      See Also:
        `setDescriptor(javax.management.Descriptor)`

    - #### setDescriptor

          public void setDescriptor(Descriptor inDescriptor)

      Sets associated Descriptor (full replace) of ModelMBeanConstructorInfo. If the new Descriptor is null, then the associated Descriptor reverts to a default descriptor. The Descriptor is validated before it is assigned. If the new Descriptor is invalid, then a RuntimeOperationsException wrapping an IllegalArgumentException is thrown.
      Specified by:
        `setDescriptor` in interface `DescriptorAccess`
      Parameters:
        `inDescriptor` - replaces the Descriptor associated with the ModelMBeanConstructor. If the descriptor does not contain all the following fields, the missing ones are added with their default values: displayName, name, role, descriptorType.
      Throws:
        `RuntimeOperationsException` - Wraps an IllegalArgumentException. The descriptor is invalid, or descriptor field "name" is present but not equal to name parameter, or descriptor field "descriptorType" is present but not equal to "operation" or descriptor field "role" is present but not equal to "constructor".
      See Also:
        `getDescriptor()`

    - #### toString
