public AlgorithmBuilderService(AlgorithmInventoryService inventoryService)

Method Details

buildAlgorithmComponentByName

public Object buildAlgorithmComponentByName(String name,
 Map<String,Object> params)

Build any algorithm component given its name and a map of parameters

Parameters:

name - component name, can be either an alias, a factory reference or a classname

params - parameter map used to create this component, provides the necessary args to call the constructor

Returns:

built component

buildAlgorithmFromString

public Algorithm<?,?> buildAlgorithmFromString(String s)

Build any algorithm from the given string description. Must follow the format: Component{param1=value1, ...}. Any component can be a parameter too, example: Alg{constructive=GRASP{alpha=1}, ls=MyLS{}}

Parameters:

s - String description

Returns:

Built component

Throws:

AlgorithmParsingException - if the built component is not a valid algorithm

buildAlgorithmComponentFromString

public Object buildAlgorithmComponentFromString(String s)

Build any algorithm from the given string description. Must follow the format: Component{param1=value1, ...}. Any component can be a parameter too, example: Alg{constructive=GRASP{alpha=1}, ls=MyLS{}}

Parameters:

s - String description

Returns:

Built component

getParser

public static AlgorithmParser getParser(String s)

Get an instance of the algorithm parser, initialized as Parser --> TokenStream --> Lexer --> String

Parameters:

s - source string

Returns:

parser with BailOutStrategy, ie fails at the first error found.
