      • dataSource

        protected final T extends javax.media.protocol.DataSource dataSource
        The DataSource which has created this instance and which contains it as one of its streams.

      • formatControl

        protected final javax.media.control.FormatControl formatControl
        The FormatControl which gives access to the Format of the media data provided by this SourceStream and which, optionally, allows setting it.

    • Method Detail

      • doRead

        protected void doRead​(javax.media.Buffer buffer)
               throws IOException
        Reads available media data from this instance into a specific Buffer.
        Specified by:
        doRead in class AbstractVideoPullBufferStream<DataSource>
        Parameters:
        buffer - the Buffer to write the available media data into
        Throws:
        IOException - if an I/O error has prevented the reading of available media data from this instance into the specified Buffer

      • close

        public void close()
        Releases the resources used by this instance throughout its existence and makes it available for garbage collection. This instance is considered unusable after closing.

        Warning: The method is not invoked by the framework, extenders may choose to invoke it.

      • doGetFormat

        protected javax.media.Format doGetFormat()
        Gets the Format of this AbstractBufferStream as directly known by it. Allows extenders to override the Format known to the DataSource which created this instance and possibly provide more details on the currently set Format.
        Returns:
        the Format of this AbstractBufferStream as directly known by it or null if this AbstractBufferStream does not directly know its Format and it relies on the DataSource which created it to report its Format

      • doSetFormat

        protected javax.media.Format doSetFormat​(javax.media.Format format)
        Attempts to set the Format of this AbstractBufferStream. Allows extenders to enable setting the Format of an existing AbstractBufferStream (in contract to setting it before the AbstractBufferStream is created by the DataSource which will provide it).
        Parameters:
        format - the Format to be set as the format of this AbstractBufferStream
        Returns:
        the Format of this AbstractBufferStream or null if the attempt to set the Format did not succeed and any last-known Format is to be left in effect

      • endOfStream

        public boolean endOfStream()
        Determines whether the end of this SourceStream has been reached. The AbstractBufferStream implementation always returns false.
        Specified by:
        endOfStream in interface javax.media.protocol.SourceStream
        Returns:
        true if the end of this SourceStream has been reached; otherwise, false

      • getContentDescriptor

        public javax.media.protocol.ContentDescriptor getContentDescriptor()
        Gets a ContentDescriptor which describes the type of the content made available by this SourceStream. The AbstractBufferStream implementation always returns a ContentDescriptor with content type equal to ContentDescriptor#RAW.
        Specified by:
        getContentDescriptor in interface javax.media.protocol.SourceStream
        Returns:
        a ContentDescriptor which describes the type of the content made available by this SourceStream

      • getContentLength

        public long getContentLength()
        Gets the length in bytes of the content made available by this SourceStream. The AbstractBufferStream implementation always returns LENGTH_UNKNOWN.
        Specified by:
        getContentLength in interface javax.media.protocol.SourceStream
        Returns:
        the length in bytes of the content made available by this SourceStream if it is known; otherwise, LENGTH_UKNOWN

      • getControls

        public Object[] getControls()
        Implements Controls.getControls(). Gets the controls available for this instance.
        Specified by:
        getControls in interface javax.media.Controls
        Returns:
        an array of Objects which represent the controls available for this instance

      • getFormat

        public javax.media.Format getFormat()
        Gets the Format of the media data made available by this AbstractBufferStream.
        Returns:
        the Format of the media data made available by this AbstractBufferStream
