readType

protected ErrorCondition readType(int count,
 ProtonBuffer buffer,
 Decoder decoder,
 DecoderState state)
                           throws DecodeException

Description copied from class: AbstractDescribedListTypeDecoder

Reads the actual type from the byte stream with the given number of encoded list elements populated

Specified by:

readType in class AbstractDescribedListTypeDecoder<ErrorCondition>

Parameters:

count - The number of entries encoded into the list body.

buffer - The source of the encoded bytes to read the value from.

decoder - The list decoder that indicates the structure of the encoded lists of elements.

state - The decoder state that was passed at the start of decoding.

Returns:

a single value that is the described type this decoder reads using the given list decoder.

Throws:

DecodeException - if an error occurs while performing the decode.
