Method Details

processInput

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

Description copied from class:&nbsp;AbstractJacksonDecoder

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

Overrides:

processInput&nbsp;in class&nbsp;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
