Constructor Detail

LazyJsonParser

public LazyJsonParser(String json)

Method Detail

getJson

public String getJson()

Returns the original JSON string.

Returns:

the original JSON string.

root

public LazyJsonParser.ReadOnlyJsonNode root()

Returns the root node of the parsed JSON as a LazyJsonParser.ReadOnlyJsonNode.

Returns:

the root node of the parsed JSON as a LazyJsonParser.ReadOnlyJsonNode.

getTextAtPath

public String getTextAtPath(String... fieldNames)

Descends into the parsed JSON data by field names and extract the text value, if any, that is provided at the specified sub-path. For example, given the JSON content:

     {
         "a" : {
             "b" : 42,
             "c" : {
                 "d" : "x",
                 "e" : true
             }
         }
     }

 

Calling getTextAsPath("a", "b", "c", "d") would return "x". However, any other call would return null, as it would refer to a path that does not exist or that contains a value that is not text.

Parameters:

fieldNames - the list of field names to descend into

Returns:

the text found at the specified location, or null if that location does not exist or contains anything other than text
