Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.
Messages are "chained" if there are only replies at the first level, i.e. 1/1.html, 1/1/1.html etc. In case of "chained" messages the message number is replaced by the icon and there is no indentation.
Inline: Display the subject line only or also the text of the posting(s); for the choice "All" the "Outline" choices are switched off.
|1||0||1||no text / full text of posting|
|2||1||All||text for level 1 only / text for All postings|
Outline: Choose the depth of the posting thread, successive toggle controls provide increasing detail.
|1||2||1||2 levels / 1 level (original posting)|
|2||3||2||3 levels / 2 levels|
|3||3||All||3 levels / all levels (all postings)|
Hi Kazuyoshi, >> tree = tf->create("testem4.XML" ,"XML" ,readOnly,createNew, >> options); > > You created a tree in a XML file: as I understand correctly, > when saving into a XML file, the tree data won't be flushed > and accumulated in memory of your machine until a run ends, > and eventually exhaust it. this is true if you deal with Tuples (and unbinned Histograms if there is no limit set for them for auto-conversion), but for binned Histograms (as is the case here) this is not an issue they have a fixed memory footprint. cheers, andreas
