public static final ValueGetter PLAIN
ValueGetter
that works for WebParam.Mode.IN
parameter.
Since it's the IN mode, the parameter is not a Holder
,
therefore the parameter itself is a value.
public static final ValueGetter HOLDER
ValueGetter
that works for Holder
,
which is WebParam.Mode.INOUT
or WebParam.Mode.OUT
.
In those WebParam.Mode
s, the parameter is a Holder
,
so the value to be sent is obtained by getting the value of the holder.
