Class XmlEventDecoder

java.lang.Object

org.springframework.core.codec.AbstractDecoder<javax.xml.stream.events.XMLEvent>

org.springframework.http.codec.xml.XmlEventDecoder

All Implemented Interfaces:

Decoder<javax.xml.stream.events.XMLEvent>

public class XmlEventDecoder
extends AbstractDecoder<javax.xml.stream.events.XMLEvent>

Decodes a DataBuffer stream into a stream of XMLEvents. That is, given the following XML:

 <root>
     <child>foo</child>
     <child>bar</child>
 </root>
 

this method with result in a flux with the following events:

1. StartDocument
2. StartElement root
3. StartElement child
4. Characters foo
5. EndElement child
6. StartElement child
7. Characters bar
8. EndElement child
9. EndElement root

Note that this decoder is not registered by default but used internally by other decoders who are there by default.

5.0

Description copied from interface: Decoder

Decode a DataBuffer input stream into a Flux of T.

Parameters:

inputStream - the DataBuffer input stream to decode

elementType - the expected type of elements in the output stream; this type must have been previously passed to the Decoder.canDecode(org.springframework.core.ResolvableType, org.springframework.util.MimeType) method and it must have returned true.

mimeType - the MIME type associated with the input stream (optional)

hints - additional information about how to do encode

Returns:

the output stream with decoded elements
