Enclosing class:

XmlStreamReader

public static class XmlStreamReader.Builder
extends AbstractStreamBuilder<XmlStreamReader,XmlStreamReader.Builder>

Builds a new XmlStreamWriter instance. Constructs a Reader using an InputStream and the associated content-type header. This constructor is lenient regarding the encoding detection.

First it checks if the stream has BOM. If there is not BOM checks the content-type encoding. If there is not content-type encoding checks the XML prolog encoding. If there is not XML prolog encoding uses the default encoding mandated by the content-type MIME type.

If lenient detection is indicated and the detection above fails as per specifications it then attempts the following:

If the content type was 'text/html' it replaces it with 'text/xml' and tries the detection again.

Else if the XML prolog had a charset encoding that encoding is used.

Else if the content type had a charset encoding that encoding is used.

Else 'UTF-8' is used.

If lenient detection is indicated an XmlStreamReaderException is never thrown.

For example:

 XmlStreamReader r = XmlStreamReader.builder()
   .setPath(path)
   .setCharset(StandardCharsets.UTF_8)
   .get();

Method Detail

get

public XmlStreamReader get()
                    throws java.io.IOException

Constructs a new instance.

This builder use the aspect InputStream, OpenOption[], httpContentType, lenient, and defaultEncoding.

You must provide an origin that can be converted to an InputStream by this builder, otherwise, this call will throw an UnsupportedOperationException.

Returns:

a new instance.

Throws:

java.lang.UnsupportedOperationException - if the origin cannot provide an InputStream.

java.io.IOException - thrown if there is a problem reading the stream.

XmlStreamReaderException - thrown if the charset encoding could not be determined according to the specification.
