Class StandardizerActionFactory

chemaxon.standardizer.StandardizerActionFactory

@PublicAPI
public class StandardizerActionFactory
extends Object

Factory of StandardizerAction objects
Initializes the list of available standardizer action based on the provided factory configuration XML files, defining the factory:

• Internal list: the factory configuration XML containing the definitions of internal (Chemaxon defined) standardizer actions, that should be available using the factory
• External list: the factory configuration XML containing the definitions of external (user defined) standardizer actions, that should be available using the factory

The schema of the definition XML is defined by the DEFAULT_CONFIGURATION_SCHEMA:

 
 <?xml version="1.0" encoding="UTF-8"?>
 <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
   <xsd:element name="configuration">

The schema defines a factory identifier and the class name for each standardizer actions. The actions can be reached by the following methods:

• All actions can be accessed by the method getAvailableStandardizerActions() or,
• each action can be accessed by the factory identifier by the method getStandardizerAction(String, Map), however with this functionality the action can be initialized with special parameters.

Example for Chemaxon's default configuration with pre-configured transformations and user-defined standardizers:

 StandardizerActionFactory.Builder builder = new StandardizerActionFactory.Builder();
 builder.add(StandardizerTest.class.getResourceAsStream(StandardizerActionFactory.DEFAULT_CONFIGURATION_PATH));
 try {
        builder.add(DotfileUtil.open(StandardizerActionFactory.USER_DEFINED_STANDARDIZERCONFIG_XML));
 } catch (IOException e) {
        // no user defined standardizer configuration found
 }
 builder.add(StandardizerTest.class.getResourceAsStream(StandardizerActionFactory.PRE_CONFIGURED_TRANSFORMATIONS));
 StandardizerActionFactory factory = builder.build();

Constructor Detail

StandardizerActionFactory

public StandardizerActionFactory()

Default constructor. Only the built in configuration file defined by DEFAULT_CONFIGURATION_PATH, and the USER_DEFINED_STANDARDIZERCONFIG_XML will be read, the default list of Standardizer Actions will be reachable by the factory

StandardizerActionFactory

public StandardizerActionFactory(String path,
                                 String externalPath)

With this constructor inner and external configuration location can be defined.

Parameters:

path - the location of the configuration XML for the inner standardizer action classes

externalPath - the location of the configuration XML for the external standardizer action classes

Method Detail
