Class ABLInitializer

java.lang.Object
  org.schwiebert.abl4j.util.ABLInitializer

public class ABLInitializer
extends Object

The ABLInitializer should be used to configure the ABL4J framework. Configuration of ABL4J is done by setting properties in a PropertiesMap. The AblInitializer must be initialized by calling initialize(String[]). It configures Abl4J by first setting default properties (see AblProperties for default values), than adding (or overriding) properties loaded from the file "abl4j.properties" (if found on the classpath), and finally adding (or overriding) the properties with the values used as parameter on initialize(String[]). Additionally, properties can be added by addProperty(String, String) etc.
Note: Although the configuration of ABL4J is accessed via the static method getProperties(), multiple configurations of ABL can be used within the same virtual machine, as the PropertiesMap is stored within an InheritableThreadLocal.
