Constructor Detail
ReplicaStore
public ReplicaStore()(Code)
Default constructor.



ReplicaStore
public ReplicaStore(Map rces)(Code)
Overloaded constructor. Intializes the member variables to the values passed.
Parameters:
  rces - map indexed by LFN's and each value is a collectionof replica catalog entries for the LFN.




Method Detail
add
public void add(Map rces)(Code)
Adds ReplicaCatalogEntries into the store. Any existing mapping of the same LFN and PFN will be replaced, including all its attributes. The ReplicaCatlogEntry ends up being stored as a ReplicaLocation object.
Parameters:
  rces - map indexed by LFN's and each value is a collectionof replica catalog entries for the LFN.



add
public void add(String lfn, Collection tuples)(Code)
Adds replica catalog entries into the store. Any existing mapping of the same LFN and PFN will be replaced, including all its attributes.
Parameters:
  lfn - the lfn.
Parameters:
  tuples - list of ReplicaCatalogEntry containing the PFN and theattributes.



add
public void add(ReplicaLocation rl)(Code)
Adds replica catalog entries into the store. Any existing mapping of the same LFN and PFN will be replaced, including all its attributes.
Parameters:
  rl - the ReplicaLocation containing a pfn and allthe attributes.



clone
public Object clone()(Code)
Returns the clone of the object. the clone



containsLFN
public boolean containsLFN(String lfn)(Code)
Returns a boolean indicating whether the store has a mapping for a particular LFN or not.
Parameters:
  lfn - the logical file name of the file. boolean



get
protected ReplicaLocation get(String key)(Code)
Returns an entry corresponding to the LFN
Parameters:
  lfn - the LFN ReplicaLocation object if exists, else null.



getLFNCount
public int getLFNCount()(Code)
Returns the number of LFN's for which the mappings are stored in the store. int



getLFNs
public Set getLFNs()(Code)
Returns the set of LFN's for which the mappings are stored in the store. Set



getLFNs
public Set getLFNs(Set lfns)(Code)
