Method Detail

readFully

public static JsonNode readFully(JsonFactory jsonFactory,
                                 String json)
                          throws IOException

Fully read the supplied JSON string into the equivalent JsonNode. Throws a JsonParseException if the string is not fully read after a first valid JsonNode is found. This may happen for input like 10 foobar that would otherwise return a NumericNode with value 10 leaving foobar unread.

Parameters:

jsonFactory - the JsonFactory from which to obtain a JsonParser to read the JSON string.

json - the JSON string to read

Returns:

the JsonNode corresponding to the input string or null if the string is null or empty.

Throws:

IOException - if there is either an underlying I/O problem or decoding issue

readFullyAsObjectNode

public static ObjectNode readFullyAsObjectNode(JsonFactory jsonFactory,
                                               String json)
                                        throws IOException
