        public ReplicaStore()
        Default constructor.

      • ReplicaStore

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

    • Method Detail

      • store

        public void store​(java.util.Map rces)
        Stores replica catalog entries into the store. It overwrites any existing entries with the same LFN's. The ReplicaCatlogEntry ends up being stored as a ReplicaLocation object.
        Parameters:
        rces - map indexed by LFN's and each value is a collection of replica catalog entries for the LFN.

      • add

        public void add​(java.util.Map rces)
        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 collection of replica catalog entries for the LFN.

      • add

        public void add​(java.lang.String lfn,
                java.util.Collection tuples)
        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.
        tuples - list of ReplicaCatalogEntry containing the PFN and the attributes.

      • add

        public void add​(ReplicaLocation rl)
        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 all the attributes.

      • getReplicaLocation

        public ReplicaLocation getReplicaLocation​(java.lang.String lfn)
        Returns a ReplicaLocation corresponding to the LFN.
        Parameters:
        lfn - the lfn for which the ReplicaLocation is required.
        Returns:
        ReplicaLocation if entry exists else null.

      • replicaLocationIterator

        public java.util.Iterator replicaLocationIterator()
        Returns an iterator to the list of ReplicaLocation objects stored in the store.
