Class OldStyleCalculatorIO

java.lang.Object
  cytoscape.visual.OldStyleCalculatorIO

public class OldStyleCalculatorIO
extends Object

This class provides methods to read property keys in the old vizmap format, construct suitable calculator objects, and install them in a supplied CalculatorCatalog. All of the calculators will have the name of the static member variable 'calcName', except that the borderColor calculator, the node height calculator, and the targetDecoration calculator will have a '2' appended to the name. (This is because in the old system, node.fillColor and node.borderColor were separate types, but are both NodeColorCalculators in the new system, and similarly with the node size and edge arrow calculators). In addition to the attribute specific calculators, this class will create a NodeAppearance and EdgeAppearanceCalculator, also named 'calcName', and set them to use the attribute calculators defined here.

Method Summary

static void	checkForCalculators(Properties props, CalculatorCatalog catalog) This method takes a properties object as an argument, expected to be the contents of a cytoscape.props file, and a CalculatorCatalog.
static void	loadCalculators(Properties props, CalculatorCatalog catalog) Given a properties object, which is expected to come from a cytoscape.props file, and a CalculatorCatalog, loads all visual mappings specified in the old format by first converting the properties into the new format and then running the converted properties through the machinery of the CalculatorIO class.

checkForCalculators

public static void checkForCalculators(Properties props,
                                       CalculatorCatalog catalog)

This method takes a properties object as an argument, expected to be the contents of a cytoscape.props file, and a CalculatorCatalog. It searches for property keys in the props that represent visual mappings in the old format, and if found brings up a UI to inform the user, prompt for a name for the calculators, and calls the loadCalculators method to convert and install these visual mappings.

Parameters:

props - a properties object, should come from cytoscape.props

catalog - the catalog in which to store any found visual mappings

loadCalculators

public static void loadCalculators(Properties props,
                                   CalculatorCatalog catalog)

Given a properties object, which is expected to come from a cytoscape.props file, and a CalculatorCatalog, loads all visual mappings specified in the old format by first converting the properties into the new format and then running the converted properties through the machinery of the CalculatorIO class.
