Class JsonData
java.lang.Object
org.mule.module.json.JsonData
- All Implemented Interfaces:
- java.io.Serializable
public class JsonData
- extends java.lang.Object
- implements java.io.Serializable
A wrapper for the JsonNode
object that
allows for nested object keys i.e. user/name will return the name property on
the user object.
There is no 'xpath' for JSON yet (though I expect Jackson to do implement this at some point).
This class provides a simple way to navigate a Json data structure. To select a child entry use -
person/name
to access array data, use square braces with an index value i.e.
person/addresses[0]/postcode
or
[0]/arrayElement
Also, multi-dimensional arrays can be accessed using:
filters[1]/init[1][0]
if a Json property name contains a '/' the name needs to be quoted with single quotes i.e.
results/'http://foo.com'/value
