        public long getVersionNumber​(edu.uiuc.ncsa.security.core.Identifier id)
        Given a version id (of form URI#version=number), return the number.
        Parameters:
        id -
        Returns:

      • createVersionedID

        public edu.uiuc.ncsa.security.core.Identifier createVersionedID​(edu.uiuc.ncsa.security.core.Identifier id,
                                                                long version)
        Given a base id and the new version number, create the identifier 
             URI#version=number
        This is to make sure everythign is created identically.
        Parameters:
        id -
        version -
        Returns:

      • main

        public static void main​(String[] args)

      • getVersions

        protected edu.uiuc.ncsa.security.core.util.DoubleHashMap<URI,​Long> getVersions​(edu.uiuc.ncsa.security.core.Identifier identifier)
        For a given object in the store, return all the versions associated with it in a DoubleHashMap. Note that the keys are of the form 
             URI#version=number
        and the value is the number. As a double hash map then you can do a reverse lookup by version number and get the unique identifier.
        Parameters:
        identifier -
        Returns:

      • getVersionsMap

        public TreeMap<Long,​edu.uiuc.ncsa.security.core.Identifiable> getVersionsMap​(edu.uiuc.ncsa.security.core.Identifiable identifiable)
        For a given object, get all the versions (not just their identifiers) and return in a map keyed by version number. This sorts the entries. Rather similar to getVersions(Identifier), this has key = number and value =URI#version=number. Use this where you need all the versions sorted by number for, e.g., display purposes.
        Parameters:
        identifiable -
        Returns:

      • getLatestVersionNumber

        protected Long getLatestVersionNumber​(edu.uiuc.ncsa.security.core.util.DoubleHashMap<URI,​Long> versionNumbers)
        Get the latest version number or return a -1 if no versions present. Remember that versions increase, so version 0 is the first made, 1 is the next,... and the highest number is the most recent version.
        Parameters:
        versionNumbers -
        Returns:

      • getVersion

        public edu.uiuc.ncsa.security.core.Identifiable getVersion​(edu.uiuc.ncsa.security.core.Identifier targetID,
                                                           long version)
                                                    throws IOException
        Given the raw id and a version number (which may be -1 to indicate using the latest) get the stored version. Might return null of there is no such version.
        Parameters:
        targetID -
        version -
        Returns:
        Throws:
        IOException

      • remove

        public void remove​(edu.uiuc.ncsa.security.core.Identifier identifier,
                   long version)
        Removed the version of the object from the store. This either returns or throws a runtime exception from the store.

        Note

        There is not a version with signature remove(Identifier) because of the risk of removing the base object if the wrong .
        Parameters:
        identifier -
        version -

      • create

        public Long create​(edu.uiuc.ncsa.security.core.Identifier identifier)

        Parameters:
        identifier -
        Returns:

      • getBaseID

        public edu.uiuc.ncsa.security.core.Identifier getBaseID​(edu.uiuc.ncsa.security.core.Identifier overloadedID)
        Removes the fragment (with the version number).
        Parameters:
        overloadedID -
        Returns:

      • getVersionNumbers

        public List<Long> getVersionNumbers​(edu.uiuc.ncsa.security.core.Identifier id)
