currentTime in interface TimestampGenerator

setCurrentTimestamp

public void setCurrentTimestamp(long timestamp)

Set the timestamp and notify the interested listeners.

Specified by:

setCurrentTimestamp in interface TimestampGenerator

setIncrementInMilliseconds

public void setIncrementInMilliseconds(long incrementInMilliseconds)

Set by how many milliseconds, the event timestamp should be increased.

Specified by:

setIncrementInMilliseconds in interface TimestampGenerator

Parameters:

incrementInMilliseconds - the timestamp incremental value.

addTimeChangeListener

public void addTimeChangeListener(TimestampGeneratorImpl.TimeChangeListener listener)

Register to listen for time changes.

Specified by:

addTimeChangeListener in interface TimestampGenerator
