      org.apache.commons.betwixt.strategy.DefaultIdStoringStrategy

DefaultIdStoringStrategy
public class DefaultIdStoringStrategy extends IdStoringStrategy (Code)

Stores every ID that given to it into an internal HashMap and returns it on request.

DefaultIdStoringStrategy.DefaultIdStoringStrategy(Map,Map) allows the implementations to be specified. For example, those who want to use identity (rather than equality) should pass a IdentityHashMap instance.

Method Detail
getReferenceFor
public String getReferenceFor(Context context, Object bean)(Code)
Returns a String id for the given bean if it has been stored previously. Otherwise returns null.
Parameters:
  context - current context, not null
Parameters:
  bean - the instance, not null id as String, or null if not found

getReferenced
public Object getReferenced(Context context, String id)(Code)
Gets an object matching the given reference.
Parameters:
  context - Context, not null
Parameters:
  id - the reference id an bean matching the given reference, or null if there is no bean matching the given reference



reset
public void reset()(Code)
Clears all beans.



setReference
public void setReference(Context context, Object bean, String id)(Code)
Stores an ID for the given instance and context. It will check first if this ID has been previously stored and will do nothing in that case.
Parameters:
  context - current context, not null
Parameters:
  bean - current instance, not null
Parameters:
  id - the ID to store
