## javax.xml.transform.stream
Class StreamResult

    java.lang.Object
      javax.xml.transform.stream.StreamResult

All Implemented Interfaces:
  Result

    public class StreamResult

extends java.lang.Object
implements Result

Acts as an holder for a transformation result, which may be XML, plain Text, HTML, or some other form of markup.

Field Summary
`static 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.

Fields inherited from interface javax.xml.transform.Result
`PI_DISABLE_OUTPUT_ESCAPING, PI_ENABLE_OUTPUT_ESCAPING`

Constructor Summary
`StreamResult()` Zero-argument default constructor.
`StreamResult(java.io.File f)` Construct a StreamResult from a File.
`StreamResult(java.io.OutputStream outputStream)` Construct a StreamResult from a byte stream.
`StreamResult(java.lang.String systemId)` Construct a StreamResult from a URL.
`StreamResult(java.io.Writer writer)` Construct a StreamResult from a character stream.

Method Summary
`java.io.OutputStream` | `getOutputStream()` Get the byte stream that was set with setOutputStream.
`java.lang.String` | `getSystemId()` Get the system identifier that was set with setSystemId.
`java.io.Writer` | `getWriter()` Get the character stream that was set with setWriter.
`void` | `setOutputStream(java.io.OutputStream outputStream)` Set the ByteStream that is to be written to.
`void` | `setSystemId(java.io.File f)` Set the system ID from a `File` reference.
`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).
`void` | `setWriter(java.io.Writer writer)` Set the writer that is to receive the result.

Field Detail

### 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.

    Constant Field Values

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 preferred 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.
