For example a stream might support seeking to a particular byte in the stream. In that case, it should implement the <code>Seekable</code> interface. Some streams allow its output format to be changed. It should then implement the <code>Formattable</code> interface. <p> Many operations are dependent on the stream data, and support cannot be determined until the stream is in use. <p> To obtain all of the objects that provide control over a stream use <code>getControls</code>. To determine if a particular kind of control is available, and obtain the object that implements the control use <code>getControl</code>.<P><DL><DT><B>See Also: </B><DD><A HREF="../../../javax/media/protocol/DataSource.html"><CODE>DataSource</CODE></A>, <A HREF="../../../javax/media/protocol/PushSourceStream.html"><CODE>PushSourceStream</CODE></A>, <A HREF="../../../javax/media/protocol/PullSourceStream.html"><CODE>PullSourceStream</CODE></A>, <A HREF="../../../javax/media/protocol/Seekable.html"><CODE>Seekable</CODE></A></DL><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Field Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static long</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/media/protocol/SourceStream.html#LENGTH_UNKNOWN">LENGTH_UNKNOWN</A></B></CODE><BR> </TD></TR></TABLE> <!-- ======== CONSTRUCTOR SUMMARY ======== --><!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Method Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> boolean</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/media/protocol/SourceStream.html#endOfStream()">endOfStream</A></B>()</CODE><BR> Find out if the end of the stream has been reached.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../../javax/media/protocol/ContentDescriptor.html">ContentDescriptor</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/media/protocol/SourceStream.html#getContentDescriptor()">getContentDescriptor</A></B>()</CODE><BR> Get the current content type for this stream.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> long</CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/media/protocol/SourceStream.html#getContentLength()">getContentLength</A></B>()</CODE><BR> Get the size, in bytes, of the content on this stream.</TD></TR></TABLE> <A NAME="methods_inherited_from_class_javax.media.Controls"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Methods inherited from interface javax.media.<A HREF="../../../javax/media/Controls.html">Controls</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../../javax/media/Controls.html#getControl(java.lang.String)">getControl</A>, <A HREF="../../../javax/media/Controls.html#getControls()">getControls</A></CODE></TD></TR></TABLE> <P><!-- ============ FIELD DETAIL =========== --><A NAME="field_detail"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=1><FONT SIZE="+2"><B>Field Detail</B></FONT></TD></TR></TABLE><A NAME="LENGTH_UNKNOWN"><!-- --></A><H3>LENGTH_UNKNOWN</H3><PRE>public static final long <B>LENGTH_UNKNOWN</B></PRE><DL></DL><!-- ========= CONSTRUCTOR DETAIL ======== --><!-- ============ METHOD DETAIL ========== --><A NAME="method_detail"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=1><FONT SIZE="+2"><B>Method Detail</B></FONT></TD></TR></TABLE><A NAME="getContentDescriptor()"><!-- --></A><H3>getContentDescriptor</H3><PRE>public <A HREF="../../../javax/media/protocol/ContentDescriptor.html">ContentDescriptor</A> <B>getContentDescriptor</B>()</PRE><DL><DD>Get the current content type for this stream.<DD><DL></DL></DD><DD><DL><DT><B>Returns:</B><DD>The current <CODE>ContentDescriptor</CODE> for this stream.</DL></DD></DL><HR><A NAME="getContentLength()"><!-- --></A><H3>getContentLength</H3><PRE>public long <B>getContentLength</B>()</PRE><DL><DD>Get the size, in bytes, of the content on this stream.
