Method Details

processInput

protected reactor.core.publisher.Flux<DataBuffer> processInput(Publisher<DataBuffer> input,
 ResolvableType elementType,
 @Nullable MimeType mimeType,
 @Nullable Map<String,Object> hints)

Description copied from class: AbstractJacksonDecoder

Process the input publisher into a flux. Default implementation returns Flux.from(Publisher), but subclasses can choose to customize this behavior.

Overrides:

processInput in class AbstractJacksonDecoder<tools.jackson.databind.json.JsonMapper>

Parameters:

input - the DataBuffer input stream to process

elementType - the expected type of elements in the output stream

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

hints - additional information about how to do encode

Returns:

the processed flux
