Method Detail

fetch

List<Tuple<Uid32,ChainTableValue>> fetch(List<Uid32> uids)
                                  throws CloudproofException

Fetch the Chain Table lines for the list of given Uid32. If a line does not exist, there should be no entry in the returned list.

Implementation of this method is always required (to search, update or compact the index).

Parameters:

uids - the unique Uid32s used as line id

Returns:

a Map of Uid32 to ChainTableValue

Throws:

CloudproofException - if anything goes wrong

insert

void insert(Map<Uid32,ChainTableValue> uidsAndValues)
     throws CloudproofException

Insert the given lines in the Chain Table.

Implementation of this method is only required to perform additions, deletions or compact operations on the index.

Parameters:

uidsAndValues - a Map of Uid32 to ChainTableValue

Throws:

CloudproofException - if anything goes wrong

delete

void delete(List<Uid32> uids)
     throws CloudproofException

Delete the lines indexed by the given UIDs Uid32 from the Chain Table.

Implementation of this method is only required to perform compact operations on the index.

Parameters:

uids - a List of Uid32

Throws:

CloudproofException - if anything goes wrong
