PLAIN
ValueGetter
that works forWebParam.Mode.IN
parameter.Since it's the IN mode, the parameter is not a
Holder
, therefore the parameter itself is a value. -
HOLDER
CreatesValueGetter
that works forHolder
, which isWebParam.Mode.INOUT
orWebParam.Mode.OUT
.In those
WebParam.Mode
s, the parameter is aHolder
, so the value to be sent is obtained by getting the value of the holder.
