Parameters:

runnable -

name - of the operation (will be used in the log)

warn_time_ms - max time allowed for this operation before issuing a warning

getInstance

public static TimeController getInstance()

Get the singleton reference

Returns:

updateState

public void updateState(ClientState newState)
                 throws IllegalArgumentException

Throws:

IllegalArgumentException

getSearchBudgetInSeconds

public static int getSearchBudgetInSeconds()

calculateForHowLongClientWillRunInSeconds

public int calculateForHowLongClientWillRunInSeconds()

hasTimeToExecuteATestCase

public boolean hasTimeToExecuteATestCase()

Is there time to execute a test case? This not only depends on which phase we are in, but also on how maximum long a test case can be left run before trying to kill its threads if timeout.

Returns:

isThereStillTimeInThisPhase

public boolean isThereStillTimeInThisPhase()

isThereStillTimeInThisPhase

public boolean isThereStillTimeInThisPhase(long ms)

getPhasePercentage

public double getPhasePercentage()

Calculate the percentage of progress in which we currently are in the phase.

Returns:

a value in [0,1] if the current phase has a timeout, otherwise a negative value
