}

Constructs an MBeanOperationInfo object. The Descriptor of the constructed object will include fields contributed by any annotations on the {@code Method} object that contain the DescriptorKey meta-annotation.

Parameters:

method - The java.lang.reflect.Method object describing the MBean operation.

description - A human readable description of the operation.

 public MBeanOperationInfo(String name,
    String description,
    MBeanParameterInfo[] signature,
    String type,
    int impact) 
{
        this(name, description, signature, type, impact, (Descriptor) null);
}

Constructs an MBeanOperationInfo object.

Parameters:

name - The name of the method.

description - A human readable description of the operation.

signature - MBeanParameterInfo objects describing the parameters(arguments) of the method. This may be null with the same effect as a zero-length array.

type - The type of the method's return value.

impact - The impact of the method, one of #INFO , #ACTION , #ACTION_INFO , #UNKNOWN .

 public MBeanOperationInfo(String name,
    String description,
    MBeanParameterInfo[] signature,
    String type,
    int impact,

        if (signature == null || signature.length == 0)
            signature = MBeanParameterInfo.NO_PARAMS;
        else
            signature = signature.clone();
        this.signature = signature;
        this.type = type;
        this.impact = impact;
        this.arrayGettersSafe =
            MBeanInfo.arrayGettersSafe(this.getClass(),
                                       MBeanOperationInfo.class);
}

Constructs an MBeanOperationInfo object.

Parameters:

name - The name of the method.

description - A human readable description of the operation.

signature - MBeanParameterInfo objects describing the parameters(arguments) of the method. This may be null with the same effect as a zero-length array.

type - The type of the method's return value.

impact - The impact of the method, one of #INFO , #ACTION , #ACTION_INFO , #UNKNOWN .

descriptor - The descriptor for the operation. This may be null which is equivalent to an empty descriptor.

{
         try {
             return super.clone() ;
         } catch (CloneNotSupportedException e) {
             // should not happen as this class is cloneable
             return null;
         }
}

Returns a shallow clone of this instance. The clone is obtained by simply calling super.clone(), thus calling the default native shallow cloning mechanism implemented by Object.clone(). No deeper cloning of any internal field is made.

Since this class is immutable, cloning is chiefly of interest to subclasses.

                p.getDescriptor().equals(getDescriptor()));
}

Compare this MBeanOperationInfo to another.

 public int getImpact() 
{
        return impact;
}

Returns the impact of the method, one of INFO, ACTION, ACTION_INFO, UNKNOWN.

 public String getReturnType() 
{
        return type;
}

Returns the type of the method's return value.

 public MBeanParameterInfo[] getSignature() 
{
        // If MBeanOperationInfo was created in our implementation,
        // signature cannot be null - because our constructors replace
        // null with MBeanParameterInfo.NO_PARAMS;
        //
        // However, signature could be null if an  MBeanOperationInfo is
        // deserialized from a byte array produced by another implementation.
        // This is not very likely but possible, since the serial form says
        // nothing against it. (see 6373150)
        //
        if (signature == null)
            // if signature is null simply return an empty array .
            //
            return MBeanParameterInfo.NO_PARAMS;
        else if (signature.length == 0)
            return signature;
        else
            return signature.clone();
}

Returns the list of parameters for this operation. Each parameter is described by an MBeanParameterInfo object.

The returned array is a shallow copy of the internal array, which means that it is a copy of the internal array of references to the MBeanParameterInfo objects but that each referenced MBeanParameterInfo object is not copied.
