Method Detail

getView

public static <T extends TemporalProposition> List<T> getView(List<T> params,
                                                              Long minValid,
                                                              Long maxValid)

Filters a list of temporal propositions by time.

Parameters:

params - a List of propositions.

minValid -

maxValid -

Returns:

getView

public static <T extends TemporalProposition> Map<String,List<T>> getView(Map<String,List<T>> paramsByKey,
                                                                          Long minValid,
                                                                          Long maxValid)

createPropositionMap

public static <T extends Proposition> Map<String,List<T>> createPropositionMap(List<T> propositions)

Divides a list of propositions up by id.

Parameters:

propositions - a List of Propositions.

Returns:

a Map of id String -> List, with propositions in the same order as they were found in the argument.

binarySearch

public static PrimitiveParameter binarySearch(List<PrimitiveParameter> params,
                                              long timestamp)

Binary search for a primitive parameter by timestamp.

Parameters:

list - a List of PrimitiveParameter objects all with the same paramId, cannot be null.

tstamp - the timestamp we're interested in finding.

Returns:

a PrimitiveParameter, or null if not found.
