extractRawValues
public java.util.List<java.lang.Object> extractRawValues(java.lang.String path)Returns the values associated with the path. Those are "low" level values, and it can handle path expression where an array/list is navigated within. -
extractValue
public java.lang.Object extractValue(java.lang.String path, @Nullable java.lang.Object nullValue)For the provided path, return its value in the source. Note that in contrast withextractRawValues(java.lang.String)
, array and object values can be returned.- Parameters:
path
- the value's path in the source.nullValue
- a value to return if the path exists, but the value is 'null'. This helps in distinguishing between a path that doesn't exist vs. a value of 'null'.- Returns:
- the value associated with the path in the source or 'null' if the path does not exist.
