# 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

  - ### 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 Details

  - ### 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`.
