Method Detail

getInstance

public static QueryManager getInstance()

createInstance

public static void createInstance(int numWorkers,
                                  int numUpdaters)

stop

public void stop()

getActiveThreads

public int getActiveThreads()

getQueryCount

public int getQueryCount()

printReport

public void printReport()

runUpdateQuery

public void runUpdateQuery(IQueryResponseListener adapter,
                           java.lang.String query,
                           java.lang.String datasource)

runUpdateQuery

public void runUpdateQuery(IQueryResponseListener adapter,
                           IQuery query)

registerQuery

public java.lang.Object registerQuery(IQuery query,
                                      IQueryResponseListener listener,
                                      java.lang.Class targetType,
                                      int updateRate,
                                      boolean runOnce,
                                      boolean notifyLoading)

Registers a new query to be run, either periodically or once. This "query" is an implementation of IQuery - anything that can retrieve a Dataset from the gateway.

Parameters:

targetType - The data type that will be pushed into the query response listener. Use Dataset.class to leave the IQuery's resulting dataset untouched. Use a scalar type to coerce the 1st value.

updateRate - The rate (actually a delay) at which to run the query.

runOnce - If true, the query will only be run once, regardless of the update rate

notifyLoading - Controls whether or not the response listener will be notified when this query is running.

unregisterQuery

public void unregisterQuery(java.lang.Object key)

setPaused

public void setPaused(boolean paused)
