## Class XmlStreamReaderException

- java.lang.Object
- - java.lang.Throwable
  - - java.lang.Exception
    - - java.io.IOException
      - - org.apache.commons.io.input.XmlStreamReaderException

- All Implemented Interfaces:
    Serializable

      public class XmlStreamReaderException
      extends IOException

  The XmlStreamReaderException is thrown by the XmlStreamReader constructors if the charset encoding can not be determined according to the XML 1.0 specification and RFC 3023.

  The exception returns the unconsumed InputStream to allow the application to do an alternate processing with the stream. Note that the original InputStream given to the XmlStreamReader cannot be used as that one has been already read.

  Since:
    2.0

    - #### XmlStreamReaderException

          public XmlStreamReaderException(String msg,
                                          String bomEnc,
                                          String xmlGuessEnc,
                                          String xmlEnc)

      Creates an exception instance if the charset encoding could not be determined.

      Instances of this exception are thrown by the XmlStreamReader.

      Parameters:
        `msg` - message describing the reason for the exception.
        `bomEnc` - BOM encoding.
        `xmlGuessEnc` - XML guess encoding.
        `xmlEnc` - XML prolog encoding.

    - #### XmlStreamReaderException

          public XmlStreamReaderException(String msg,
                                          String ctMime,
                                          String ctEnc,
                                          String bomEnc,
                                          String xmlGuessEnc,
                                          String xmlEnc)

      Creates an exception instance if the charset encoding could not be determined.

      Instances of this exception are thrown by the XmlStreamReader.

      Parameters:
        `msg` - message describing the reason for the exception.
        `ctMime` - MIME type in the content-type.
        `ctEnc` - encoding in the content-type.
        `bomEnc` - BOM encoding.
        `xmlGuessEnc` - XML guess encoding.
        `xmlEnc` - XML prolog encoding.

  - ### Method Detail

    - #### getBomEncoding

          public String getBomEncoding()

      Returns the BOM encoding found in the InputStream.
      Returns:
        the BOM encoding, null if none.

    - #### getContentTypeEncoding

          public String getContentTypeEncoding()

      Returns the encoding in the content-type used to attempt determining the encoding.
      Returns:
        the encoding in the content-type, null if there was not content-type, no encoding in it or the encoding detection did not involve HTTP.

    - #### getContentTypeMime

          public String getContentTypeMime()

      Returns the MIME type in the content-type used to attempt determining the encoding.
      Returns:
        the MIME type in the content-type, null if there was not content-type or the encoding detection did not involve HTTP.

    - #### getXmlEncoding

          public String getXmlEncoding()

      Returns the encoding found in the XML prolog of the InputStream.
      Returns:
        the encoding of the XML prolog, null if none.

    - #### getXmlGuessEncoding

          public String getXmlGuessEncoding()

      Returns the encoding guess based on the first bytes of the InputStream.
      Returns:
        the encoding guess, null if it couldn't be guessed.
