java.lang.Object
com.jayway.jsonpath.spi.json.AbstractJsonProvider
com.jayway.jsonpath.spi.json.JacksonJsonNodeJsonProvider
org.apache.druid.data.input.impl.FastJacksonJsonNodeJsonProvider
All Implemented Interfaces:
com.jayway.jsonpath.spi.json.JsonProvider
public class FastJacksonJsonNodeJsonProvider extends com.jayway.jsonpath.spi.json.JacksonJsonNodeJsonProvider
Custom json-path JsonProvider override to circumvent slow performance when encountering null paths as described in https://github.com/json-path/JsonPath/issues/396 Note that this only avoids errors for map properties, avoiding the exception on array paths is not possible without patching json-path itself
