- All Implemented Interfaces:
- LabelPathToIdMapper
- public class ClientLabelPathToIdMapperAndCreator
- extends ClientLabelPathToIdMapper
Maps LabelPaths to ReactorObjectIds. Uses a Map to dereference
ReactorObjectIds as necessary to do the mapping. This class was
written with the assumption that the Map contains properly
initialized ProcessMediation objects. For example, an Operand's
getProcess() method should not return the id of a Status.
However, this precondition is not enforced and errors that result
from this precondition not being met were not taken into
consideration when writing the class. This class should be
improved to either enforce this precondition or gracefully handle
errors that result from it not being met.

ClientLabelPathToIdMapperAndCreator
public ClientLabelPathToIdMapperAndCreator()
- Constructs a ClientLabelPathToIdMapperAndCreator that utilizes caching to
improve performance. The new mapper will not be useful until it
is given a Map to use to look up ProcessMediationObjects by a
call to setObjectMap().
ClientLabelPathToIdMapperAndCreator
public ClientLabelPathToIdMapperAndCreator(java.util.Map objectMap)
throws ProcessMediationException
- Constructs a mapper that uses objectMap to look up objects by
their ids and utilizes caching to improve performance.
- Parameters:
objectMap
- the Map to use to look up objects by their ids
- Throws:
ProcessMediationException
- if the Map contains values other than ProcessMediationObjects or
Maps an id to an object with a different id.
getIdSet
public java.util.Set getIdSet(com.oakgrovesystems.reactor.LabelPath pathToMap,
java.lang.Class filterClass)
- Maps a LabelPath to a Set of ReactorObjectIds
- Specified by:
getIdSet
in interface LabelPathToIdMapper
- Overrides:
getIdSet
in class ClientLabelPathToIdMapper
- Parameters:
pathToMap
- The LabelPath that must resolve to an object for
that object to be included in the returned Set.filterClass
- The Class with which an object must be assignment compatible
in order to be included in the returned Set.
- Returns:
- The Set of ReactorObjectIds of all Objects o available to the
mapper such that the LabelPath pathToMap will resolve to o and
filterClass.isInstance(o)==true. Returns an empty set if
no such objects are available to the mapper.
