ModelMBeanConstructorInfopublic class ModelMBeanConstructorInfo extends MBeanConstructorInfo implements Cloneable, 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:
name : constructor name
descriptorType : must be "operation"
role : must be "constructor"
displayName : human readable name of constructor
visibility : 1-4 where 1: always visible 4: rarely visible
presentationString : xml formatted string to describe how to present operation
The persistPolicy and currencyTimeLimit fields are not valid for the constructor.
The default descriptor will have the name, descriptorType, displayName and role fields. |

| Methods Summary |
|---|
| public java.lang.Object | clone()Creates and returns a new ModelMBeanConstructorInfo which is a duplicate of this ModelMBeanConstructorInfo.
if (tracing())

}

{

}

| | private boolean | isValid(javax.management.Descriptor inDesc)Tests that the descriptor is valid and adds appropriate default fields not already
specified. Field values must be correct for field names.
Descriptor must have the same name as the operation,the descriptorType field must
be "operation", the role field must be set to "constructor".
The following fields will be defaulted if they are not already set:
displayName=this.getName()

| | private void | readObject(java.io.ObjectInputStream in)Deserializes a {@link ModelMBeanConstructorInfo} from an {@link ObjectInputStream}.
// New serial form ignores extra field "currClass"
in.defaultReadObject();
| | public void | setDescriptor(javax.management.Descriptor inDescriptor)Sets associated Descriptor (full replace) of

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.
