java - Why the emphasis on typed attributes/methods in MBean definition? -

-

from oracle's definition of mbeans:

mbeans managed beans, java objects represent resources managed. mbean has management interface consisting of:

  1. named , typed attributes can read , written.
  2. named , typed operations can invoked
  3. typed notifications can be> emitted mbean

why emphasis on typed in each of points above? java typed language , attributes/methods in java class have type attached them. finding definition confusing. or missing fundamental here? using typed mean different?

jmx has more restrictive typing characteristics because often, types providing form of "identity" or signature bean attribute or operation. in addition, jmx supports notion of open types complex type broken down primitive definitions can represented externally jvm (perhaps in jconsole specific class might not in classpath.)

don't hung on though... means mbean's attributes defined name, , type. no surprise there :)

i hoping can me lost. need modify workflow trac if ticket type spr, gets assigned our qa, , ones allowed closing ticket. otherwise, goes test team closed. as well, need ticket status flow follows: new ticket(bug) -> assigned(dev) -> fixed(re-assigned test or spr) -> closed/re-opened currently appears ticket set closed after dev fixes issue. i not familliar trac @ , have been hammering away @ 2 days , can't seem work. incredibly appreciated! try advancedticketworkflowplugin , because able act differently based on ticket field values. relevant here: triage operation based on ticket type according wiki documentation: accept = new -> * accept.name = accept ticket workflow accept.operations = triage accept.triage_field = type accept.triage_split = defect->new_defect,enhancement->new_enhancement (see more complete example on wiki page linked above)
