hashCode</H3>
<PRE>
public int <B>hashCode</B>()</PRE>
<DL>
<DD>Returns the hash code value for this <code>OpenMBeanOperationInfoSupport</code> instance. 
 <p>
 The hash code of an <code>OpenMBeanOperationInfoSupport</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>OpenMBeanOperationInfoSupport</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>
 However, note that another instance of a class implementing the <code>OpenMBeanOperationInfo</code> interface
 may be equal to this <code>OpenMBeanOperationInfoSupport</code> instance as defined by <A HREF="../../../javax/management/openmbean/OpenMBeanOperationInfoSupport.html#equals(java.lang.Object)"><CODE>equals(java.lang.Object)</CODE></A>, 
 but may have a different hash code if it is calculated differently.
 <p>
 As <code>OpenMBeanOperationInfoSupport</code> instances are immutable, the hash code for this instance is calculated once,
 on the first call to <code>hashCode</code>, and then the same value is returned for subsequent calls.

<DL>
<DD>Returns a string representation of this <code>OpenMBeanOperationInfoSupport</code> instance. 
 <p>
 The string representation consists of the name of this class (ie <code>javax.management.openmbean.OpenMBeanOperationInfoSupport</code>), 
 and the name, signature, return open type and impact of the described operation.
 <p>
 As <code>OpenMBeanOperationInfoSupport</code> instances are immutable, 
 the string representation for this instance is calculated once,
