This interface indicates that decoder supports consuming large strings by chunks via consumeChunk method. Currently, only streaming json decoder implements this interface. Please note that this interface is only applicable to streaming decoders. That means that it is not possible to use some JsonTreeDecoder features like polymorphism with this interface.
Method allows decoding a string value by fixed-size chunks. Usable for handling very large strings that may not fit in memory. Chunk size is guaranteed to not exceed 16384 chars (but it may be smaller than that). Feeds string chunks to the provided consumer.
