Returns:

the time interval in milliseconds.

getVolume

int getVolume()

Describes the power level of the tone, expressed in dBm0

Returns:

the value in dBm0

activate

void activate()

Starts media processing.

Specified by:

activate in interface Component

deactivate

void deactivate()

Terminates media processing.

Specified by:

deactivate in interface Component

flushBuffer

void flushBuffer()

Flushes buffer.

clearDigits

void clearDigits()

Clears buffer content.

addListener

void addListener(DtmfDetectorListener listener)
                 throws TooManyListenersException

Throws:

TooManyListenersException

removeListener

void removeListener(DtmfDetectorListener listener)

clearAllListeners

void clearAllListeners()
