Method Detail

addFragmentSourceObserver

public void addFragmentSourceObserver(java.util.Observer o)

For notification of events This object to be used by objects only interested in being notified about the changing numbers of available records

getFragment

public InformationFragment getFragment(java.lang.String handle)
                                throws PresentException

Allow access to the set of objects based on a handle system (DOI?)

getFragment

public InformationFragment getFragment(int index)
                                throws PresentException

Position based access to the result set. Implementation must be 1 based: IE, First record in result set is 1 not 0. Local mappings (e.g to vector) must account for this!

getFragment

public InformationFragment[] getFragment(int starting_fragment,
                                         int count)
                                  throws PresentException

Position based range access to the result set. Implementation must be 1 based: IE, First record in result set is 1 not 0. Local mappings (e.g to vector) must account for this!

getFragmentCount

public int getFragmentCount()

Current number of fragments available

destroy

public void destroy()

Release all resources and shut down the object

getStatusReport

public java.lang.String getStatusReport()

Return a string based status report intended for display to the user Typical FragmentSource states include EMPTY, FILLING, COMPLETE, and SOURCE_NO_LONGER_AVAILABLE these should be presented in a human readable form.
