->JsonNode clj

(->JsonNode)

(->JsonNode mapper)

Returns a transducer that given a Java object maps it to a JsonNode. Accepts an optional Jackson ObjectMapper.

execute clj

(execute expression)

(execute expression opts)

Returns a transducer that accepts JsonNode on which the expression will be applied. Optional opts are supported that are passed for the jq.api/stream-processor. Specific opts for the transducer: :cat - whether to catenate output, default true

JsonNode->value clj

(JsonNode->value)

(JsonNode->value mapper)

Returns a transducer that give a JsonNode maps it to a Java Object. Accepts an optional Jackson ObjectMapper.

parse clj

(parse)

(parse mapper)

Returns a transducer that given a JSON String parses it into a JsonNode. Accepts an optional Jackson ObjectMapper.

pretty-print clj

(pretty-print)

(pretty-print mapper)

Same as the serializer but the output string is indented. ObjectMapper is copied to prevent side effects in case mapper is shared.

process clj

(process expression)

(process expression opts)

(process expression opts mapper)

Returns a convenience transducer that:

• maps a Java Object to a JsonNode;
• maps a JQ expression on the JsonNode;
• catenates the output;
• maps a JsonNode to a JavaObject. Accept opts that will be passed to the jq.api/stream-processor Accepts a Jackson ObjectMapper that will be used for both

rdr->json-nodes clj

(rdr->json-nodes)

(rdr->json-nodes mapper)

Returns a transducer that given a java.io.Reader parses it into a stream of JsonNode. Accepts an optional Jackson ObjectMapper.

serialize clj

(serialize)

(serialize mapper)

Returns a transducer that given a JsonNode serializes it to a String. Accepts an optional Jackson ObjectMapper.
