Eclipse debugger variable list bullet icon decorators

hi,

i'm trying to figure it out but have no idea...

in the debugger of the eclipse plug-in, in the variables list, what is the meaning of an entry that has a tiny "F" in the top-right corner of its bullet icon. like i have

(L) root
       *F  capacity            20
       *    children            2
       *    id                       0
       *F  id                       -1

do i need to be worried that there are two entries (with different values) for field 'id' in this case? what does the 'F' stand for?

thanks, -sciss-

indeed i had to be worried, just found a severe bug in my code. like
i did

Node( private var id: ID ) {
def getID = id
def setID( newID: ID ) { id = newID }
}

Index( id: ID ) extends Node( id ) {
def chooseSubtree( pathBuffer: scala.collection.mutable.Stack[ ID ]) {
pathBuffer.push( id )
// ...
}
}

so i was using in 'chooseSubtree' the old value of 'id' that was
handed in the _constructor_.... so switching that to getID would fix
it.

but i think that
- the compiler would warn me about those variable shadowings
- this proofs once more that the weird concept of scala's
constructors has deficiencies...

also... i don't understand why the 'id' from Index( id: ID ) is _at
all_ visible in a method and not just the constructor... am i doing
something wrong here... i mean there must be a way that 'id' is not
visible at all in chooseSubtree, or not?

thanks, -sciss-

ah... ok, yes capacity is a val. see my other posting: i accidentally
got two entries for 'id', one is the 'final' constructor argument,
the other is a variable in the superclass.
