<DL>
<DD>Returns an array of <tt>OpenMBeanParameterInfo</tt> instances
 describing each parameter in the signature of the operation
 described by this <tt>OpenMBeanOperationInfo</tt> instance.
 Each instance in the returned array should actually be a
 subclass of <tt>MBeanParameterInfo</tt> which implements the
 <tt>OpenMBeanParameterInfo</tt> interface (typically <A HREF="../../../javax/management/openmbean/OpenMBeanParameterInfoSupport.html" title="class in javax.management.openmbean"><CODE>OpenMBeanParameterInfoSupport</CODE></A>).

<DL>
<DD>Returns the fully qualified Java class name of the values
 returned by the operation described by this
 <tt>OpenMBeanOperationInfo</tt> instance.  This method should
 return the same value as a call to

public boolean <B>equals</B>(<A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/Object.html" title="class or interface in java.lang">Object</A>&nbsp;obj)</PRE>
<DL>
<DD>Compares the specified <var>obj</var> parameter with this <code>OpenMBeanOperationInfo</code> instance for equality. 
 <p>
 Returns <tt>true</tt> if and only if all of the following statements are true:
 <ul>
 <li><var>obj</var> is non null,</li>
 <li><var>obj</var> also implements the <code>OpenMBeanOperationInfo</code> interface,</li>
 <li>their names are equal</li>
 <li>their signatures are equal</li>
 <li>their return open types are equal</li>
 <li>their impacts are equal</li>
 </ul>
 This ensures that this <tt>equals</tt> method works properly for <var>obj</var> parameters which are
 different implementations of the <code>OpenMBeanOperationInfo</code> interface.
 <br>&nbsp;
<P>
<DD><DL>
<DT><B>Parameters:</B><DD><CODE>obj</CODE> - the object to be compared for equality with this <code>OpenMBeanOperationInfo</code> instance;
<DT><B>Returns:</B><DD><code>true</code> if the specified object is equal to this <code>OpenMBeanOperationInfo</code> instance.</DL>
</DD>
</DL>
<HR>

<A NAME="hashCode()"><!-- --></A><H3>
hashCode</H3>
<PRE>
public int <B>hashCode</B>()</PRE>
<DL>
<DD>Returns the hash code value for this <code>OpenMBeanOperationInfo</code> instance. 
 <p>
 The hash code of an <code>OpenMBeanOperationInfo</code> instance is the sum of the hash codes
 of all elements of information used in <code>equals</code> comparisons 
 (ie: its name, return open type, impact and signature, where the signature hashCode is calculated by a call to 
  <tt>java.util.Arrays.asList(this.getSignature).hashCode()</tt>). 
 <p>
 This ensures that <code> t1.equals(t2) </code> implies that <code> t1.hashCode()==t2.hashCode() </code> 
 for any two <code>OpenMBeanOperationInfo</code> instances <code>t1</code> and <code>t2</code>, 
 as required by the general contract of the method
 <a href="http://java.sun.com/j2se/1.3/docs/api/java/lang/Object.html#hashCode()"> 
 <code>Object.hashCode</code> </a>.
 <p>
<P>
<DD><DL>

<DT><B>Returns:</B><DD>the hash code value for this <code>OpenMBeanOperationInfo</code> instance</DL>

<PRE>
public <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/String.html" title="class or interface in java.lang">String</A> <B>toString</B>()</PRE>
<DL>
<DD>Returns a string representation of this <code>OpenMBeanOperationInfo</code> instance. 
 <p>
 The string representation consists of the name of this class (ie <code>javax.management.openmbean.OpenMBeanOperationInfo</code>), 
 and the name, signature, return open type and impact of the described operation.
<P>
<DD><DL>

<DT><B>Returns:</B><DD>a string representation of this <code>OpenMBeanOperationInfo</code> instance</DL>
