Method Detail

listComponents

<any> listComponents(java.lang.String nodePath,
                     java.lang.String cuType,
                     java.lang.String cuFilter,
                     ClusterContext context)
              throws ManagementException

Returns all control units of the given type for which the current host is responsible for.

Parameters:

cuType -

nodePath -

cuFilter -

context -

Returns:

Throws:

ManagementException

boolean isHandableByFilterPlugins(java.lang.String cuType,
                                  java.lang.String cuFilter)
                           throws ManagementException

Tests whether filtering could be performed using FilterPlugin-s utilizing database searches. This serves as information for the execution plan of supplied cuType and cuFilter are passed to the listComponents method.

Parameters:

cuType -

cuFilter -

Returns:

true if filtering could be performed using FilterPlugin-s utilizing database searches, false if filtering can be done only by iterating through control units and matching them one by one.

Throws:

ManagementException

boolean amIResponisbleFor(ControlUnitID cuId)
                   throws ManagementException

Tests whether current host is currently responsible for a given control unit.

Parameters:

cuId -

Returns:

Throws:

ManagementException

match

boolean match(ControlUnitID cuId,
              java.lang.String cuFilter)
       throws ManagementException

Tests whether given control units matches given filter.

Parameters:

cuId -

cuFilter -

Returns:

Throws:

Returns a sql query that lists all control unit ids of a given cu type for which the local backend host is currently responsible. Could be used by group providers as inner select to their sql queries, thus restricting the result set to contain only control units for which the local backend host is currently responsible. Example of usage: "select * from my_group where my_group.cu_id in (" + makeLoadBalanceRestrictionSQLQuery(cuType, context) + ")"

Parameters:

cuType -

context -

Returns:

Parameters:

set1 -

set2 -

Returns:

Throws:

ManagementException
