getMaxInFlight

public int getMaxInFlight()

Specified by:

getMaxInFlight in interface Limit.SampleWindow

Returns:

Maximum number of inflight observed during the sample window

getSampleCount

public int getSampleCount()

Specified by:

getSampleCount in interface Limit.SampleWindow

Returns:

Number of observed RTTs in the sample window

didDrop

public boolean didDrop()

Specified by:

didDrop in interface Limit.SampleWindow

Returns:

True if there was a timeout

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
