Detailed Description

template<typename CharT, typename Traits = std::char_traits<CharT>>
class Teuchos::basic_FancyOStream< CharT, Traits >

std::ostream subclass that performs the magic of indenting data sent to an std::ostream object among other things.

Use the typedef FancyOStream for support for the char character type.

Indentation of the stream is accomplished through creating basic_OSTab objects (i.e. typedef OSTab). For example, when accepting a FancyOStream object, one might indent it like:

void someFunc(FancyOStream &out)
{
OSTab(out);
out << "This is indented!\n";
...
}

In addition to indenting output, this stream object can also print various types of information at the beginning of each line. The type of information supported is:

See FancyOutputting_test.cpp for examples of how this class is used and the output it generates.

Constructor & Destructor Documentation

template<typename CharT , typename Traits >
Teuchos::basic_FancyOStream< CharT, Traits >::basic_FancyOStream ( const RCP< std::basic_ostream< char_type, traits_type > > &  oStream,
const std::basic_string< char_type, traits_type > &  tabIndentStr = " ",
const int  startingTab = 0,
const bool  showLinePrefix = false,
const int  maxLenLinePrefix = 10,
const bool  showTabCount = false,
const bool  showProcRank = false 
)
explicit

Constructor.

Parameters
oStream[in/out] Output stream to wrap.
tabIndentStr[in] String to use as a prefix for each tab level. Default is a single space (per tab level).
startingTab[in] Starting tab level. Default is 0.
showLinePrefix[in] Whether to show the line prefix. (This does not include the tab indent string. Tabs will indent regardless.)
maxLenLinePrefix[in] Maximum number of characters in the line prefix. (This does not include the tab indent string.)
showTabCount[in] Whether to show the tab count in front of each line of text.
showProcRank[in] Whether to print the rank of the calling (MPI) process in front of each line of text. If you set this to true, you must call setProcRankAndSize() before printing to this output stream, or the process rank will not be defined.

The following things are called "front matter":

  • Rank of the calling (MPI) process
  • Line prefix
  • Tab count

This object may print any or all of these things in front of each line. (Delimit each line by using std::endl, not with "\n". The latter is not portable in any case!) You may control which of these get printed by the corresponding Boolean argument of this constructor.

template<typename CharT , typename Traits >
basic_FancyOStream< CharT, Traits > & Teuchos::basic_FancyOStream< CharT, Traits >::setShowAllFrontMatter ( const bool  showAllFrontMatter)

Control whether this stream prints "front matter.".

"Front matter" includes the following things:

  • Rank of the calling (MPI) process
  • Line prefix
  • Tab count

This object may print any or all of these things in front of each line. (Delimit each line by using std::endl, not with "\n". The latter is not portable in any case!) You may control individually which of these get printed by the corresponding Boolean argument of this object's constructor. You may also call this method to turn on or off printing of all front matter.

const int  numProcs 
)

Set the (MPI) process rank and the number of processes in the communicator.

Parameters
procRank[in] The rank of the calling process.
numProcs[in] The number of processes in the communicator.

You must call this method before you may call setOutputToRootOnly().

template<typename CharT , typename Traits >
basic_FancyOStream< CharT, Traits > & Teuchos::basic_FancyOStream< CharT, Traits >::setOutputToRootOnly ( const int  rootRank)

Set the stream to print only on the (MPI) process with the given rank.

Precondition
The calling process rank and the number of processes in the communicator were set via a call to setProcRankAndSize().
Parameters
rootRank[in] The rank of the process on which to print. The convention is to use Process 0 as the "root" process, but this is not required.
Warning
The effect of this method is currently irreversible. This commits downstream users of this output stream to the same assignment of ranks to processes. The result of calling setProcRankAndSize() after this method has been called is undefined. It will likely have no effect.

void Teuchos::basic_FancyOStream< CharT, Traits >::pushTab ( const int  tabs = 1)

Push one or more tabs.

Users should generally not call this method directly. It is better to use OSTab to automate the process. OSTab's constructor calls pushTab() for you. It also calls popTab() automatically on scope exit, whether the scope was exited normally or by an exception throw. This "puts things back how you found them."
