Detailed Description

template<typename Type>
class Util::MatrixParam< Type >

An array-valued parameter in a parameter file.

MatrixParam is a base class for objects that read and write the value of an matrix or 2D array containing a list of parameters of the same
type.

Matrices can be read and written in either of two formats:

Bracketed format begins with a label immediately followed by an opening delimiter on a line by itself, followed by several data lines, and ends with a closing delimiter.
Bracket-free format begins with a label on the same line as the first line of data, with no opening or closing bracket delimiters.

Different subclasses may use different formats for the data lines, and different choices of delmiting brackets (e.g., square brackets or parentheses). Two different conventions are in use:

Row data format puts values of all the elements in each row of the matrix on a single line, with rows appearing in order of increasing index, as in standard linear algebra matrix format.
Element format puts each element on a single line, in which each line contains the row and column index followed by the value.

Either row or element data format may be input and output in either bracketed or bracket-free format. The choice of whether to use bracketed or bracket-free format is determined by the global bracket policy returned by the function Util::BracketPolicy::get().

If the policy is BracketPolicy::Forbidden, the bracket-free format must be used for both reading and writing.
If the policy is BracketPolicy::Required, the bracketed format must be used for both reading and writing.
If the policy is BracketPolicy::Optional, then either format can be read, but the bracketed format is used for writing.

◆ readLabel()

template<typename Type >

void Util::MatrixParam< Type >::readLabel ( std::istream & in )

protectedvirtual

Read parameter label from an input stream.

Parameters

in	input stream from which to read

Reimplemented from Util::Parameter.

References Util::BracketPolicy::get(), and Util::Label::isMatched().

◆ readEndBracket()

template<class Type >

void Util::MatrixParam< Type >::readEndBracket ( std::istream & in )

protected

Read the closing delimiter, if any.

Attempts to read closing bracket iff hasBrackets is true. Throws an exception if hasBrackets is true but the expected delimiter is not found.

Write the end bracket delimiter, if any.

Parameters

out	output stream to which to write

std::string Util::ParamComponent::indent ( ) const

Return indent string for this object (string of spaces).

◆ readValue()

template<typename Type >

virtual void Util::Parameter::readValue ( std::istream & in )

inlinevirtual

Read parameter value from an input stream.

Parameters

in	input stream from which to read

Reimplemented from Util::Parameter.

Definition at line 202 of file Parameter.h.

◆ load()

template<typename Type >

void Util::Parameter::load ( Serializable::IArchive & ar )

virtual

Load from an archive.

An optional Parameter loads the value of an isActive flag, and then loads the parameter value only if the isActive is true. A required Parameter simply loads the parameter value. The variable associated with an optional Parameter must be set to its default value before attempting to load the parameter. Optional parameters should be saved either using the save() method of an associated Parameter object or using the appropriate overloaded Parameter::saveOptional() static member function, which both use the required format.

Parameters

ar	input archive from which to load

Reimplemented from Util::Parameter.

Definition at line 150 of file Parameter.cpp.

Referenced by Util::ParamComposite::loadCArray2D(), Util::ParamComposite::loadDMatrix(), and Util::ParamComposite::loadDSymmMatrix().

◆ save()

template<typename Type >

void Util::Parameter::save ( Serializable::OArchive & ar )

virtual

Save to an archive.

An optional Parameter saves the value of the isActive flag, and then saves a parameter value only if the isActive is true. A required Parameter simply saves its value. The label string is not saved to the archive.

The overloaded static saveOptional functions can also be used to save optional parameter values in this format.

Parameters

ar	output archive to which to save

Reimplemented from Util::Parameter.

Definition at line 165 of file Parameter.cpp.

◆ label()

template<typename Type >

std::string Util::Parameter::label ( ) const

Return label string.

bool Util::Parameter::isRequired ( ) const

Is this an optional parameter?

Definition at line 175 of file Parameter.cpp.

◆ isActive()

template<typename Type >

bool Util::Parameter::isActive ( ) const

Is this parameter active?
