setLogger

public void setLogger(org.apache.commons.logging.Log logger)

Set an alternative logger to use than the one based on the class name.

Parameters:

logger - the logger to use

getLogger

Return the currently configured Logger.

getDecodableMimeTypes

public List<MimeType> getDecodableMimeTypes()

Description copied from interface: Decoder

Return the list of MIME types supported by this Decoder. The list may not apply to every possible target element type and calls to this method should typically be guarded via canDecode(elementType, null). The list may also exclude MIME types supported only for a specific element type. Alternatively, use Decoder.getDecodableMimeTypes(ResolvableType) for a more precise list.

Specified by:

getDecodableMimeTypes in interface Decoder<T>

Returns:

the list of supported MIME types

canDecode

public boolean canDecode(ResolvableType elementType,
 @Nullable MimeType mimeType)

Description copied from interface: Decoder

Whether the decoder supports the given target element type and the MIME type of the source stream.

Specified by:

canDecode in interface Decoder<T>

Parameters:

elementType - the target element type for the output stream

mimeType - the mime type associated with the stream to decode (can be null if not specified)

Returns:

true if supported, false otherwise

decodeToMono

public reactor.core.publisher.Mono<T> decodeToMono(Publisher<DataBuffer> inputStream,
 ResolvableType elementType,
 @Nullable MimeType mimeType,
 @Nullable Map<String,Object> hints)

Description copied from interface: Decoder

Decode a DataBuffer input stream into a Mono of T.

Specified by:

decodeToMono in interface Decoder<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(ResolvableType, 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 decode

Returns:

the output stream with the decoded element
