Interface ConditionMatcher

All Superinterfaces:

VersionableService

public interface ConditionMatcher
extends VersionableService

Applications can register this interface as service in order to predefine the matching of attribute-value conditions when filtering control units of certain control unit types. This service should be registered with service property ControlConstants.TYPE and value of String or String[] specifying the control unit type(s), that this matcher shall concern. When more than one matchers are registered for the same control unit type, the service with higher ranking overtakes priority. If collision appears for services with equal rankings, the latest registered one will be chosen.

MatchResult match(java.lang.String[] attribute,
                  java.lang.String searchValue,
                  int comparisonOperation,
                  com.prosyst.mprm.backend.ms.cu.spi.ControlUnitState cuState)
           throws ManagementException

Invoked by the system to match an attribute against given value and compared by given comparison operator. The custom matcher returns its decision with a MatchResult object where the possible results are "matched", "not matched" or "can not match" if the matcher does not consider to be capable of matching the given attribute.

Parameters:

attribute - attribute name tokens.

searchValue - the value specified in the processed filter.

comparisonOperation - comparison operator.

cuState - object representing the control unit for which the attribute is matched.

Returns:

match result.

Throws:

ManagementException
