Class XmlEventDecoder

java.lang.Object

org.springframework.core.codec.AbstractDecoder<XMLEvent>

org.springframework.http.codec.xml.XmlEventDecoder

All Implemented Interfaces:

org.springframework.core.codec.Decoder<XMLEvent>

public class XmlEventDecoder
extends org.springframework.core.codec.AbstractDecoder<XMLEvent>

Decodes a DataBuffer stream into a stream of XMLEvents.

Given the following XML:

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

this decoder will produce 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 is used internally by other decoders which are registered by default.

Since:

5.0

Method Detail

setMaxInMemorySize

public void setMaxInMemorySize(int byteCount)

Set the max number of bytes that can be buffered by this decoder. This is either the size the entire input when decoding as a whole, or when using async parsing via Aalto XML, it is size one top-level XML tree. When the limit is exceeded, DataBufferLimitException is raised.

By default this is set to 256K.

Parameters:

byteCount - the max number of bytes to buffer, or -1 for unlimited

Since:

5.1.11

getMaxInMemorySize

public int getMaxInMemorySize()

Return the configured byte count limit.
