Detailed Description

Tabbing utility for output. Constructing a new Tabs object automatically increments the number of tabs to be written. When the Tabs object goes out of scope, the original tabs level is restored.

The tab size and character can be specified through the setTabSize() and setTabChar() methods, for example,

The tab character can be set on an object-by-object basis through a constructor argument.

By default, a header giving the depth of tabs is written to each line; this can simplify scanning by eye for when a given tab level is reached. This header can be turned off by calling

 Tabs::showDepth() = false;

Example: the code

 void f()
   Tabs tab;
   cout << tab << "in f()" << std::endl;
   cout << tab << "leaving f()" << std::endl;

 void g()
   Tabs tab0;
   cout << tab0 << "in g()" << std::endl;
   for (int i=0; i<3; i++)
       Tabs tab1();
       cout << tab1 << "i=" << i << std::endl;
   cout << tab0 << "leaving g()" << std::endl;
writes the following output
 [0]  in f()
 [1]    in g()
 [1]    leaving g()
 [0]  leaving f()

Change the tab size. Default is 2.

Definition at line 82 of file PlayaTabs.hpp.

static bool& Playa::Tabs::showDepth (  )  [inline, static]

Indicate whether to print the tab depth as a header for each line.
