    Methods
    Modifier and Type | Method and Description
    --- | ---
    `java.io.OutputStream` | `getOutputStream()` Get the byte stream that was set with setOutputStream.

    - #### FEATURE

          public static final java.lang.String FEATURE

      If `TransformerFactory.getFeature(java.lang.String)` returns true when passed this value as an argument, the Transformer supports Result output of this type.

  - ### Constructor Detail

    - #### StreamResult

          public StreamResult()

      Zero-argument default constructor.

    - #### StreamResult

          public StreamResult(java.io.OutputStream outputStream)

      Construct a StreamResult from a byte stream. Normally, a stream should be used rather than a reader, so that the transformer may use instructions contained in the transformation instructions to control the encoding.
      Parameters:
        `outputStream` - A valid OutputStream reference.

    - #### StreamResult

          public StreamResult(java.io.Writer writer)

      Construct a StreamResult from a character stream. Normally, a stream should be used rather than a reader, so that the transformer may use instructions contained in the transformation instructions to control the encoding. However, there are times when it is useful to write to a character stream, such as when using a StringWriter.
      Parameters:
        `writer` - A valid Writer reference.

    - #### StreamResult

          public StreamResult(java.lang.String systemId)

      Construct a StreamResult from a URL.
      Parameters:
        `systemId` - Must be a String that conforms to the URI syntax.

    - #### StreamResult

          public StreamResult(java.io.File f)

      Construct a StreamResult from a File.
      Parameters:
        `f` - Must a non-null File reference.

  - ### Method Detail

    - #### setOutputStream

          public void setOutputStream(java.io.OutputStream outputStream)

      Set the ByteStream that is to be written to. Normally, a stream should be used rather than a reader, so that the transformer may use instructions contained in the transformation instructions to control the encoding.
      Parameters:
        `outputStream` - A valid OutputStream reference.

    - #### getOutputStream

          public java.io.OutputStream getOutputStream()

      Get the byte stream that was set with setOutputStream.
      Returns:
        The byte stream that was set with setOutputStream, or null if setOutputStream or the ByteStream constructor was not called.

    - #### setWriter

          public void setWriter(java.io.Writer writer)

      Set the writer that is to receive the result. Normally, a stream should be used rather than a writer, so that the transformer may use instructions contained in the transformation instructions to control the encoding. However, there are times when it is useful to write to a writer, such as when using a StringWriter.
      Parameters:
        `writer` - A valid Writer reference.

    - #### getWriter

          public java.io.Writer getWriter()

      Get the character stream that was set with setWriter.
      Returns:
        The character stream that was set with setWriter, or null if setWriter or the Writer constructor was not called.

    - #### setSystemId

          public void setSystemId(java.lang.String systemId)

      Set the systemID that may be used in association with the byte or character stream, or, if neither is set, use this value as a writeable URI (probably a file name).
      Specified by:
        `setSystemId` in interface `Result`
      Parameters:
        `systemId` - The system identifier as a URI string.

    - #### setSystemId

          public void setSystemId(java.io.File f)

      Set the system ID from a `File` reference.

      Note the use of `File.toURI()` and `File.toURL()`. `toURI()` is prefered and used if possible. To allow JAXP 1.3 to run on J2SE 1.3, `toURL()` is used if a `NoSuchMethodException` is thrown by the attempt to use `toURI()`.

      Parameters:
        `f` - Must a non-null File reference.

    - #### getSystemId

          public java.lang.String getSystemId()

      Get the system identifier that was set with setSystemId.
      Specified by:
        `getSystemId` in interface `Result`
      Returns:
        The system identifier that was set with setSystemId, or null if setSystemId was not called.
