Constructor Detail

LatencyQuery

public LatencyQuery()

Constructs a new query stream position query object. A position query is used to query the current position of playback in the streams, in some format.

Method Detail

setLatency

public void setLatency(boolean live,
                       long minLatency,
                       long maxLatency)

Answers a latency query.

Parameters:

live - if there is a live element upstream

minLatency - the minimal latency of the live element

maxLatency - the maximal latency of the live element

isLive

public boolean isLive()

Gets whether the element has a live element upstream or not.

Returns:

true if the element has a live element upstream.

getMinimumLatency

public long getMinimumLatency()

Gets the minimum latency of the live element.

Returns:

The minimum latency of the live element.

getMaximumLatency

public long getMaximumLatency()

Gets the maximum latency of the live element.

Returns:

The maximum latency of the live element.

toString

public String toString()

Gets the latency as a user-readable string.

Overrides:

toString in class NativeObject

Returns:

A string representing the latency.
