Distance *make(QString str, QObject *parent)

Make a Distance from a string. This function converts the abbreviation character + into it's full-length alternative.

Abbreviation	Translation
+	PipeDistance. Each Distance linked by a + is turned into a child of a single PipeDistance. "Distance1+Distance2" becomes "Pipe([Distance1,Distance2])". Templates are projected through the children of a pipe in series, the output of one become the input of the next.

The expanded string is then passed to Factory::make to be turned into a distance.

• function definition:

  static Distance *make(QString str, QObject *parent)
  

• parameters:

  Parameter	Type	Description
  str	QString	String describing the distance
  parent	QObject *	Parent of the object to be created

• output: (Distance *) Returns a pointer to the Distance described by the string

• see: Factory::make
• example:

  Distance::make("Distance1+Distance2+Distance3")->description(); // returns "Pipe(distances=[Distance1,Distance2,Distance3])".
  

QSharedPointer<Distance> fromAlgorithm(const QString &algorithm)

Create a Distance from an OpenBR algorithm string. The Distance is created using everything to the right of a : or a ! in the string.

• function definition:

  static QSharedPointer<Distance> fromAlgorithm(const QString &algorithm)
  

• parameters:

  Parameter	Type	Description
  algorithm	const QString &	Algorithm string to construct the Distance from

• output: (QSharedPointer<Distance>) Returns a pointer to the Distance described by the algorithm.

• example:

  Distance::fromAlgorithm("EnrollmentTransform:Distance")->decription(); // returns "Distance" Distance::fromAlgorithm("EnrollmentTransform!Distance1+Distance2")->decription(); // returns "Pipe(distances=[Distance1,Distance2])
