public interface PathFunction

Defines the pattern by which a function can be executed over the result set in the particular path being grabbed. The Function's input is the content of the data from the json path selector and its output is defined via the functions behavior. Thus transformations in types can take place. Additionally, functions can accept multiple selectors in order to produce their output. Created by matt@mjgreenwood.net on 6/26/15.

Method Detail

invoke

java.lang.Object invoke(java.lang.String currentPath,
                        PathRef parent,
                        java.lang.Object model,
                        EvaluationContext ctx)

Invoke the function and output a JSON object (or scalar) value which will be the result of executing the path

Parameters:

currentPath - The current path location inclusive of the function name

parent - The path location above the current function

model - The JSON model as input to this particular function

ctx - Eval context, state bag used as the path is traversed, maintains the result of executing

Returns:
