Method Detail

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<io.netty.buffer.ByteBuf>

Overrides:

canDecode in class AbstractDecoder<io.netty.buffer.ByteBuf>

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

decode

public io.netty.buffer.ByteBuf decode(DataBuffer dataBuffer,
                                      ResolvableType elementType,
                                      @Nullable
                                      MimeType mimeType,
                                      @Nullable
                                      Map<String,Object> hints)

Description copied from interface: Decoder

Decode a data buffer to an Object of type T. This is useful for scenarios, that distinct messages (or events) are decoded and handled individually, in fully aggregated form.

Parameters:

dataBuffer - the DataBuffer to decode

elementType - the expected output type

mimeType - the MIME type associated with the data

hints - additional information about how to do encode

Returns:

the decoded value, possibly null
