 Constructor via a parameter list.

 Assignment operator.
void reset (Teuchos::ParameterList &p)
 Reset the printing parameters.
bool isPrintType (NOX::Utils::MsgType type) const
 Returns true if this is a valid print type.
std::ostream & out () const
 Returns the ostream for printing if this proces is the print process. Returns a Teuchos::oblackholestream otherwise.
std::ostream & out (NOX::Utils::MsgType type) const
 Returns the ostream for printing if this process is the print process and the print type is valid. Returns a Teuchos::oblackholestream otherwise.
std::ostream & pout () const
 Returns the ostream for printing regardless of the print processor. Only use this call if you want all processes to print to the ostream.
std::ostream & pout (NOX::Utils::MsgType type) const
 Returns the ostream for printing if the print type matches. Only use this call if you want all processes to print to the ostream for the print type.
std::ostream & err () const
 Returns the error stream for printing if this is the print process.
std::ostream & perr () const
 Returns the error stream for printing to all processors. Only use this call if you want all processes to print to the error stream.
void print (ostream &os) const
 Print this object.
Sci sciformat (double dval) const
 Creates a Sci object which can be used in an output stream for printing a double precision number in scientific format with an arbitrary precision. The precision is that specificed by the Utils object.

Static Public Member Functions

Fill fill (int filln, char fillc= '*')
 Creates a Fill object which can be used in an output stream to insert an arbitrary number of a given character. The default character is an asterick.
Sci sciformat (double dval, int prec)
 Static version of sciformat().

Detailed Description

Provides printing utilities.

The following parameters are valid for this class and should be defined in the "Printing" sublist of the solver parameter list.

The public variables should never be modified directly.


Member Enumeration Documentation

enum NOX::Utils::MsgType
 

Message types for printing.

Note that each message type is a power of two - this is very important. They can be added together to specify which messages you wish to receive.

Enumeration values:
Error  Errors are always printed.
Warning  2^0
OuterIteration  2^1
InnerIteration  2^2
Parameters  2^3
Details  2^4
OuterIterationStatusTest  2^5
LinearSolverDetails  2^6
TestDetails  2^7
StepperIteration  2^8 -- For LOCA
StepperDetails  2^9 -- For LOCA
StepperParameters  2^10 -- For LOCA
Debug  2^12


Constructor & Destructor Documentation

NOX::Utils::Utils int  outputInformation = 0xf,
int  MyPID = 0,
int  outputProcess = 0,
int  outputPrecision = 3,
const Teuchos::RefCountPtr< std::ostream > &  outputStream = Teuchos::null,
const Teuchos::RefCountPtr< std::ostream > &  errorStream = Teuchos::null
 

Constructor.

The final two arguments are a reference counted pointers to ostreams. This defaults to std::cout and std::cerr if not supplied. Users should only supply this argument if they want output directed to a std::ostream other than the defaults. If so, they must wrap the ostream in a reference counted pointer for safe memory management.


Member Function Documentation

NOX::Utils::Fill NOX::Utils::fill int  filln,
char  fillc = '*'
[static]
 

Creates a Fill object which can be used in an output stream to insert an arbitrary number of a given character. The default character is an asterick.

For example,

 cout << Utils::fill(10) << "or" << Utils::fill(10,'-'); 

This is modeled after the Form and Bound_form objects in Stroustrup, C++ Programming Langauge, 3rd ed., Chapter 21.4.

NOX::Utils::Sci NOX::Utils::sciformat double  dval  )  const
 

Creates a Sci object which can be used in an output stream for printing a double precision number in scientific format with an arbitrary precision. The precision is that specificed by the Utils object.

For example,

 cout << Utils::sci(d) << "or" << Utils::sci(d,2); 

This is modeled after the Form and Bound_form objects in Stroustrup, C++ Programming Langauge, 3rd ed., Chapter 21.4.
