Class PropertiesAsConstantsGenerator

java.lang.Object

de.tsl2.nano.util.codegen.ClassGenerator

de.tsl2.nano.util.codegen.PropertiesAsConstantsGenerator

public class PropertiesAsConstantsGenerator
extends ClassGenerator

Generates an interface with integer constants (hashed keys or simple sequence) to be used to get resource values. saves ram-space using integers instead of full string keys. provides type-safed access to property values.

ON CONSTRUCTION:

 - (generate key/values to property file (from bean-attribute informations))
 - load key/values from property file.
 - map them into a Map[Integer, Object] where the integers are the hashes of the keys. 
 - generate an interface for that property file with: 
   public static final Integer [key-as-constant-name]=[hash(key)];
   
   These constants can then be used to get the mapped values:
      myresourceBundle.getString([generated-interface].[key-name-as-constant-name]);
