      Methods 
      Modifier and Type Method and Description
      boolean canFail()
      Tells whether the reader can fail to return a valid chunk.
      The current Use would be a modified version of StreamChunkReader, which is configured to only manage audio streams.
      GUID[] getApplyingIds()
      Returns the GUIDs identifying the types of chunk, this reader will parse.
      Chunk read(GUID guid, java.io.InputStream stream, long chunkStart)
      Parses the chunk.

    • Method Detail

      • canFail

        public boolean canFail()
        Tells whether the reader can fail to return a valid chunk.
        The current Use would be a modified version of StreamChunkReader, which is configured to only manage audio streams. However, the primary GUID for audio and video streams is the same. So if a stream shows itself to be a video stream, the reader would return null.
        Specified by:
        canFail in interface ChunkReader
        Returns:
        true, if further analysis of the chunk can show, that the reader is not applicable, despite the header GUID identification told it can handle the chunk.
      • getApplyingIds

        public GUID[] getApplyingIds()
        Returns the GUIDs identifying the types of chunk, this reader will parse.
        Specified by:
        getApplyingIds in interface ChunkReader
        Returns:
        the GUIDs identifying the types of chunk, this reader will parse.
      • read

        public Chunk read(GUID guid,
                 java.io.InputStream stream,
                 long chunkStart)
                   throws java.io.IOException
        Parses the chunk.
        Specified by:
        read in interface ChunkReader
        Parameters:
        guid - the GUID of the chunks header, which is about to be read.
        stream - source to read chunk from.
        No GUID is expected at the currents stream position. The length of the chunk is about to follow.
        chunkStart - the position in stream, the chunk starts.
        Returns:
        the read chunk. (Mostly a subclass of Chunk).
        Throws:
        java.io.IOException - On I/O Errors.
