## Class StAXResult

- java.lang.Object
- - javax.xml.transform.stax.StAXResult

- All Implemented Interfaces:
    Result

      public class StAXResult
      extends Object
      implements Result

  Acts as a holder for an XML `Result` in the form of a StAX writer,i.e. `XMLStreamWriter` or `XMLEventWriter`. `StAXResult` can be used in all cases that accept a `Result`, e.g. `Transformer`, `Validator` which accept `Result` as input.

  Since:
    1.6
  See Also:
    JSR 173: Streaming API for XML, `XMLStreamWriter`, `XMLEventWriter`

    Fields
    Modifier and Type | Field and Description
    --- | ---
    `static String` | `FEATURE` If `TransformerFactory.getFeature(String name)` 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

    Constructor and Description
    `StAXResult(XMLEventWriter xmlEventWriter)` Creates a new instance of a `StAXResult` by supplying an `XMLEventWriter`.
    `StAXResult(XMLStreamWriter xmlStreamWriter)` Creates a new instance of a `StAXResult` by supplying an `XMLStreamWriter`.

  - ### Method Summary

    All Methods Instance Methods Concrete Methods
    Modifier and Type | Method and Description
    --- | ---
    `String` | `getSystemId()` The returned system identifier is always `null`.
    `XMLEventWriter` | `getXMLEventWriter()` Get the `XMLEventWriter` used by this `StAXResult`.
    `XMLStreamWriter` | `getXMLStreamWriter()` Get the `XMLStreamWriter` used by this `StAXResult`.
    `void` | `setSystemId(String systemId)` In the context of a `StAXResult`, it is not appropriate to explicitly set the system identifier.

- - ### Field Detail

    - #### FEATURE

          public static final String FEATURE

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

  - ### Constructor Detail

    - #### StAXResult

          public StAXResult(XMLEventWriter xmlEventWriter)

      Creates a new instance of a `StAXResult` by supplying an `XMLEventWriter`.

      `XMLEventWriter` must be a non-`null` reference.

      Parameters:
        `xmlEventWriter` - `XMLEventWriter` used to create this `StAXResult`.
      Throws:
        `IllegalArgumentException` - If `xmlEventWriter` == `null`.

    - #### StAXResult

          public StAXResult(XMLStreamWriter xmlStreamWriter)

      Creates a new instance of a `StAXResult` by supplying an `XMLStreamWriter`.

      `XMLStreamWriter` must be a non-`null` reference.

      Parameters:
        `xmlStreamWriter` - `XMLStreamWriter` used to create this `StAXResult`.
      Throws:
        `IllegalArgumentException` - If `xmlStreamWriter` == `null`.

  - ### Method Detail

    - #### getXMLEventWriter

          public XMLEventWriter getXMLEventWriter()

      Get the `XMLEventWriter` used by this `StAXResult`.

      `XMLEventWriter` will be `null` if this `StAXResult` was created with a `XMLStreamWriter`.

      Returns:
        `XMLEventWriter` used by this `StAXResult`.

    - #### getXMLStreamWriter

          public XMLStreamWriter getXMLStreamWriter()

      Get the `XMLStreamWriter` used by this `StAXResult`.

      `XMLStreamWriter` will be `null` if this `StAXResult` was created with a `XMLEventWriter`.

      Returns:
        `XMLStreamWriter` used by this `StAXResult`.

    - #### setSystemId

          public void setSystemId(String systemId)

      In the context of a `StAXResult`, it is not appropriate to explicitly set the system identifier. The `XMLEventWriter` or `XMLStreamWriter` used to construct this `StAXResult` determines the system identifier of the XML result.

      An `UnsupportedOperationException` is always thrown by this method.

      Specified by:
        `setSystemId` in interface `Result`
      Parameters:
        `systemId` - Ignored.
      Throws:
        `UnsupportedOperationException` - Is always thrown by this method.

    - #### getSystemId

          public String getSystemId()

      The returned system identifier is always `null`.

      Specified by:
        `getSystemId` in interface `Result`
      Returns:
        The returned system identifier is always `null`.
