    - #### PDFCFFStream

          public PDFCFFStream(java.lang.String type)

  - ### Method Detail

    - #### getSizeHint

          protected int getSizeHint()
                             throws java.io.IOException

      Description copied from class: `AbstractPDFStream`
      Returns a value that hints at the size of the encoded stream. This is used to optimize buffer allocation so fewer buffer reallocations are necessary.
      Specified by:
        `getSizeHint` in class `AbstractPDFStream`
      Returns:
        an estimated size (0 if no hint can be given)
      Throws:
        `java.io.IOException` - in case of an I/O problem

    - #### outputRawStreamData

          protected void outputRawStreamData(java.io.OutputStream out)
                                      throws java.io.IOException

      Description copied from class: `AbstractPDFStream`
      Sends the raw stream data to the target OutputStream.
      Specified by:
        `outputRawStreamData` in class `AbstractPDFStream`
      Parameters:
        `out` - OutputStream to write to
      Throws:
        `java.io.IOException` - In case of an I/O problem

    - #### populateStreamDict

          protected void populateStreamDict(java.lang.Object lengthEntry)

      Description copied from class: `AbstractPDFStream`
      Populates the dictionary with all necessary entries for the stream. Override this method if you need additional entries.
      Overrides:
        `populateStreamDict` in class `AbstractPDFStream`
      Parameters:
        `lengthEntry` - value for the /Length entry

    - #### setData

          public void setData(byte[] data)
                       throws java.io.IOException

      Throws:
        `java.io.IOException`
