Planning Results API

Below is a list of provided Results API functions for the planning application. Each function must be called using a Thinknode meta request.

For more information on Thinknode meta requests, please visit the Thinknode documentation.

For an example in calling a Planning Results API function, please refer to the planning_results_api_example.py in the .decimal astroid-script-library.

// PLAN RESULTS API
 
// Some general notes about the API...
//
// All API functions here are exposed as request generators. This is for
// multiple reasons...
//
// * It allows the implementation to return (possibly chained) 'meta'
//   requests that retrieve information that's needed to actually get the
//   results.
//
// * It allows users to inspect the intermediate requests to see how result
//   calculations are composed.
//
// 'xx_summary' structures give a light-weight summary of an 'xx'.
// It includes only textual information and IDs. There's no real data.
// The real data is retrieved separately through other API calls.
//
// A 'report' is general information about an object. This can include both
// user commentary and parameters that are automatically captured by the app.
//
// A report has no prescribed structure. It's only meant to be consumed
// visually by humans. The generating app version has full flexibility in what
// it chooses to include. Thus, apps that use this API should NOT analyze the
// contents of the report. If apps need information that's not directly
// available outside the report, then either this API is missing information
// or they're looking for information that's specific to a particular version
// of the planning app (in which case they should be using that version's data
// structures directly).
//
// There's some redundancy in the API (for example, the fact that you can get
// the DVHs for structures even though you have enough info to compute them
// yourself). This is not just a matter of convenience but is a way of ensuring
// that important results are captured as they were originally computed.
