Detailed Description

Reads and parses information from a Nektar++ XML session file.

This class provides an interface to Nektar++-specific content in a supplied XML document. It also initialises a Nektar++ session including setting up communication for parallel execution and where necessary partitioning the supplied mesh for running across multiple processes.

A session should be initialised at the beginning of a user's application by passing the command-line arguments. This not only allows the SessionReader to extract the name of the XML document to load containing Nektar++ session information, but also supplies the MPI arguments necessary for setting up parallel communication. The SessionReader should be initialised using the CreateInstance function:

LibUtilities::SessionReaderSharedPtr vSession
         = LibUtilities::SessionReader::CreateInstance(argc, argv);

The instance vSession can now be passed to other key Nektar++ components during their construction.

Note

At the end of the user application, it is important to call the Finalise routine in order to finalise any MPI communication and correctly free resources.

The SessionReader class provides streamlined, validated access to session parameters, solver information and functions defined within a Nektar++ XML document. The available routines and their usage is documented below.

In the case of solver information properties, the classes to which these parameters are pertinent may register with the SessionReader class the set of valid values for a given property. Such values may also be associated with an enumeration value for more transparent use of the property values in code.

CreateInstance() [1/2]

static SessionReaderSharedPtr Nektar::LibUtilities::SessionReader::CreateInstance ( int  argc, char *  argv[]  )

Creates an instance of the SessionReader class.

This function should be used by an application to instantiate the session reader. It should be called at the very beginning of the application before any other processing of command-line arguments. After instantiating the class and setting up any parallel communication, it also calls the main initialisation of the object.

String to enumeration map for Solver Info parameters.

This map of maps stores the list of valid string values for a number of solver information parameters. The top level map connects different parameter names to their list of possible values. The list of possible values is also a map, mapping a valid string to a corresponding enum value.

This list is populated through the RegisterEnumValue static member function which is called statically from various classes to register the valid values for solver info parameters associated with them. The map is therefore fully populated before the SessionReader class is instantiated and a file is read in and parsed.

RegisterDefaultSolverInfo()

std::string Nektar::LibUtilities::SessionReader::RegisterDefaultSolverInfo ( const std::string &  pName, const std::string &  pValue  )

inlinestatic

Registers the default string value of a solver info property.

A default value for a given solver info property may be registered using this function. The property will take this value until it is overwritten by a value specified in the XML document, or specified as a command-line argument. Usage has the form:

std::string GlobalLinSys::def
    = LibUtilities::SessionReader::RegisterDefaultSolverInfo(
        "GlobalSysSoln","DirectMultiLevelStaticCond");

Parameters

pName	The name of the property.
pValue	The default value of the property.

Returns

The default value of the property provided by #pValue.

        {

RegisterEnumValue()

std::string Nektar::LibUtilities::SessionReader::RegisterEnumValue ( std::string  pEnum, std::string  pString, int  pEnumValue  )

inlinestatic

Registers an enumeration value.

A set of valid values for a given solver info property may be registered using this function. It must be called statically during the initialisation of a static variable. For example:

std::string GlobalLinSys::lookupIds[2] = {
    LibUtilities::SessionReader::RegisterEnumValue(
                                 "GlobalSysSoln",

                                 "GlobalSysSoln",
                                 "DirectStaticCond",
                                 MultiRegions::eDirectStaticCond)
}

Parameters

pEnum	The name of the property.
pString	A valid value for the property.
pEnumValue	An enumeration value corresponding to this value.

Returns

The value for the property provided by #pString.
