Interface CharacterProvider

public interface CharacterProvider

This interface controls the storage of character related documents. The basic concept is that each character can have attachments of a specific

invalid reference 
format
and
invalid reference 
type
. Examples for those attachments may be portrait image (type CHARACTER, format IMAGE) serialized character data (type CHARACTER, format RULESPECIFIC) or a background story (type BACKGROUND, format PDF).

All the attachments are collected in a CharacterHandle. CharacterHandles itself belong to a

invalid reference 
de.rpgframework.core.Player
and have a RoleplayingSystem assigned. 

  // Get the player that represents yourself
 Player myself = RPGFrameworkLoader.getInstance().getPlayerService().getMyself();

  // Obtain an instance of the character provider ...
 CharacterProvider charProv = RPGFrameworkLoader.getInstance().getCharacterProvider();

  // Obtain an instance of the character provider ...
 for (CharacterHandle handle : charProv.getCharacters(myself)) {
    // ... do something
 }

      type - What us described in this attachment
