public OpenMBeanOperationInfoSupport(String name, String description, OpenMBeanParameterInfo[] signature, OpenType returnOpenType, int impact)
The signature array parameter is internally copied, so that subsequent changes to the array referenced by signature have no effect on this instance.
name
- cannot be a null or empty string.description
- cannot be a null or empty string.signature
- can be null or empty if there are no parameters to describe.returnOpenType
- cannot be null: use SimpleType.VOID for operations that return nothing.impact
- can be only one of ACTION, ACTION_INFO or INFO.
IllegalArgumentException
- if name or description are null or empty string,
or returnOpenType is null,
or impact is not one of ACTION, ACTION_INFO or INFO.
ArrayStoreException
- If signature is not an array of instances of a subclass of MBeanParameterInfo.Method Detail |

Returns true if and only if all of the following statements are true:

- the object to be compared for equality with this OpenMBeanOperationInfoSupport

if the specified object is equal to this OpenMBeanOperationInfoSupport
instance.public int hashCode()
OpenMBeanOperationInfoSupport
instance.
The hash code of an OpenMBeanOperationInfoSupport
instance is the sum of the hash codes
of all elements of information used in equals
comparisons
(ie: its name, return open type, impact and signature, where the signature hashCode is calculated by a call to
java.util.Arrays.asList(this.getSignature).hashCode()).
This ensures that t1.equals(t2)
implies that t1.hashCode()==t2.hashCode()
for any two OpenMBeanOperationInfoSupport
instances t1
and t2
,
as required by the general contract of the method
Object.hashCode
.
However, note that another instance of a class implementing the OpenMBeanOperationInfo
interface
may be equal to this OpenMBeanOperationInfoSupport
instance as defined by equals(java.lang.Object)
,
but may have a different hash code if it is calculated differently.
As OpenMBeanOperationInfoSupport
instances are immutable, the hash code for this instance is calculated once,
on the first call to hashCode
, and then the same value is returned for subsequent calls.

OpenMBeanOperationInfoSupport

The string representation consists of the name of this class (ie javax.management.openmbean.OpenMBeanOperationInfoSupport
),
and the name, signature, return open type and impact of the described operation.
As OpenMBeanOperationInfoSupport
instances are immutable,
the string representation for this instance is calculated once,
on the first call to toString
, and then the same value is returned for subsequent calls.
