Package org.jitsi.impl.neomedia.protocol

Class RewritablePullBufferDataSource

  • All Implemented Interfaces:
    javax.media.Controls, javax.media.Duration, javax.media.protocol.CaptureDevice, javax.media.protocol.Controls, 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

      • 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
