All Implemented Interfaces:

javax.media.Controls, javax.media.Duration, javax.media.protocol.CaptureDevice, InbandDTMFDataSource, MuteDataSource

public class RewritablePullBufferDataSource
extends PullBufferDataSourceDelegate<javax.media.protocol.PullBufferDataSource>
implements MuteDataSource, InbandDTMFDataSource

Implements a PullBufferDataSource wrapper which provides mute support for the wrapped instance.

Because the class wouldn't work for our use case without it, CaptureDevice is implemented and is being delegated to the wrapped DataSource (if it supports the interface in question).

Constructor Detail

RewritablePullBufferDataSource

public RewritablePullBufferDataSource(javax.media.protocol.PullBufferDataSource dataSource)

Initializes a new RewritablePullBufferDataSource instance which is to provide mute support for a specific PullBufferDataSource.

Parameters:

dataSource - the PullBufferDataSource the new instance is to provide mute support for

Method Detail

setMute

public void setMute(boolean mute)

Sets the mute state of this DataSource.

Specified by:

setMute in interface MuteDataSource

Parameters:

mute - true to mute this DataSource; otherwise, false

isMute

public boolean isMute()

Determines whether this DataSource is mute.

Specified by:

isMute in interface MuteDataSource

Returns:

true if this DataSource is mute; otherwise, false

addDTMF

public void addDTMF(DTMFInbandTone tone)

Adds a new inband DTMF tone to send.

Specified by:

addDTMF in interface InbandDTMFDataSource

Parameters:

tone - the DTMF tone to send.

isSendingDTMF

public boolean isSendingDTMF()

Determines whether this DataSource sends a DTMF tone.

Returns:

true if this DataSource is sending a DTMF tone; otherwise, false.

getWrappedDataSource

public javax.media.protocol.PullBufferDataSource getWrappedDataSource()

Get wrapped DataSource.

Returns:

wrapped DataSource

getControl

public Object getControl(String controlType)

Implements Controls.getControl(String). Delegates to the wrapped DataSource. Overrides CaptureDeviceDelegatePullBufferDataSource.getControl(String) because the wrapped DataSource may not be a CaptureDevice yet it still needs to give access to the control. Overrides the super implementation to include the type hierarchy of the very wrapped dataSource instance into the search for the specified controlType.

Specified by:

getControl in interface javax.media.Controls

Overrides:

getControl in class PullBufferDataSourceDelegate<javax.media.protocol.PullBufferDataSource>

Parameters:

controlType - a String value which names the type of the control to be retrieved

Returns:

an Object which represents the control of the requested controlType of the wrapped DataSource

getStreams

public javax.media.protocol.PullBufferStream[] getStreams()

Implements PullBufferDataSource.getStreams(). Wraps the streams of the wrapped PullBufferDataSource into MutePullBufferStream instances in order to provide mute support to them.

Specified by:

getStreams in class PullBufferDataSourceDelegate<javax.media.protocol.PullBufferDataSource>

Returns:

an array of PullBufferStream instances with enabled mute support
