f that the specific transform needs go here }, ... ] Each operation is called in the order that it is specified within the array. The original input to Chainr is passed into the first operation, with its output passed into the next, and so on. The output of the final operation is returned from Chainr. Currently, [operation-name] can be any of the following: - shift: (Shiftr) a tool for moving parts of an input JSON document to a new output document - default: (Defaultr) a tool for applying default values to the provided JSON document - remove: (Removr) a tool for removing specific values from the provided JSON document - sort: (Sortr) sort the JSON document, purely for human readability / debugging - java: passes control to whatever Java class you specify as long as it implements the Transform interface Shift, default, and remove operation all require a "spec", while sort does not. [ { "operation": "shift", "spec" : { // shiftr spec } }, { "operation": "sort" // sort does not need a spec }, ... ] Custom Java classes that implement Tranform and/or SpecDriven can be loaded by specifying the full className to load. Additionally, if upon reflection of the class we see that it is an instance of a SpecTransform, then we will construct it with a the supplied "spec" object. [ { "operation": "com.bazaarvoice.tuna.CustomTransform", "spec" : { .. } // optional spec to use to construct a CustomTransform if it has the SpecTransform marker interface. }, ... ]
