public OpenMBeanOperationInfoSupport(String name, String desc, OpenMBeanParameterInfo[] sig, OpenType<?> type, int impact)
null
value for the parameter information is the same
as passing in an empty array. A copy of the parameter array is
taken, so later changes have no effect. The name and the
description may not be equal to the empty string, and neither
the name, description nor the open return type may be
null
. The value of impact
must be
one of the four valid values
(MBeanOperationInfo.INFO
,
MBeanOperationInfo.ACTION
,
MBeanOperationInfo.ACTION_INFO
and
MBeanOperationInfo.UNKNOWN
).
name
- the name of the constructor.desc
- a description of the attribute.sig
- the signature of the method, as a series

- the open return type of the method.impact
- the impact of performing the operation.
IllegalArgumentException
- if the name, description or
open return type is null
,
the name or description are equal to
the empty string, or the impact factor
is not one of the values enumerated
above.
ArrayStoreException
- if the members of the signature array
are not assignable to
