Method Detail

createGetSearchTerm

default TKeyData createGetSearchTerm(SDatabaseEntry key,
                                     SDatabaseEntryBase data)

This method helps to create the TKeyData argument used in a remote get call.

Parameters:

key - the key argument

data - the data argument

Returns:

the search term used for a remote get call

createPGetSearchTerm

default TKeyDataWithPKey createPGetSearchTerm(SDatabaseEntry sKey,
                                              SDatabaseEntry pKey,
                                              SDatabaseEntry pData)

This method helps to create the TKeyDataWithPKey argument used in a remote pGet call.

Parameters:

sKey - the sKey argument

pKey - the pKey argument

pData - the pData argument

Returns:

the search term used for a remote pGet call

updateKeyData

default void updateKeyData(SDatabaseEntry key,
                           SDatabaseEntryBase data,
                           java.util.List<TKeyData> pairs)

This method helps to update the output arguments of a get call, using values returned from a remote get call.

Parameters:

key - the key argument

data - the data argument

pairs - the key / data pairs retrieved from a remote get call

updateTuple

default void updateTuple(SDatabaseEntry sKey,
                         SDatabaseEntry pKey,
                         SDatabaseEntry pData,
                         TKeyDataWithPKey tuple)

This method helps to update the output arguments of a pGet call, using values returned from a remote pGet call.

Parameters:

sKey - the sKey argument

pKey - the pKey argument

pData - the pData argument

tuple - the tuple returned from a remote pGet call

remoteGet

default SOperationStatus remoteGet(SDatabaseEntry key,
                                   SDatabaseEntryBase data,

                                    SDatabaseEntry pKey,
                                    SDatabaseEntry pData,
                                    GetHelper.RemotePGetFunction pGetFunc)
                             throws SDatabaseException

Throws:
