Intervention flows

This method returns the \(m\) intervention flows of a result. These are the flows that cross the boundary with the environment of the calculated system (this is why the short name is EnviFlow in the API). In regionalized calculations these flows can be pairs of flows and locations, the same flow can occur in different locations (with possibly different characterisation factors). The rows of the intervention matrix are indexed by these \(m\) intervention flows (and the columns by the \(n\) technosphere flows):

$$ B \in \mathbb{R}^{m \times n} $$

Examples

Python IPC

envi_flows = result.get_envi_flows()
print(
    pd.DataFrame(
        [
            (ef.is_input, ef.flow.name, ef.flow.category, ef.flow.ref_unit)
            for ef in envi_flows
        ],
        columns=["Is input?", "Flow", "Category", "Unit"],
    ).head()
)

#    Is input?          Flow                                     Category Unit
# 0      False   1,4-dioxane             Elementary Flows/air/unspecified   kg
# 1      False      oryzalin            Elementary Flows/soil/groundwater   kg
# 2      False    Sethoxydim            Elementary Flows/soil/groundwater   kg
# 3      False  Chlorpyrifos  Elementary Flows/air/low population density   kg
# 4      False          lead             Elementary Flows/air/unspecified   kg

JSON-RPC via Fetch API

The example below shows the usage of this method using the JSON-RPC protocol via the Fetch API which is available in modern web-browsers or platforms like Deno.

  let resp = await fetch("http://localhost:8080", {
    method: "POST",
    body: JSON.stringify({
      jsonrpc: "2.0",
      id: 1,
      method: "result/envi-flows",
      params: {
        "@id": "66dcc7d0-ce47-46bf-b77a-ada4b4c95169",
      }
    })
  });
  let v = await resp.json();
  console.log(v);
  // {
  //   jsonrpc: "2.0",
  //   result: [
  //     {
  //       flow: {
  //         "@type": "Flow",
  //         "@id": "60ea7a31-8f27-46af-bfe5-66417f00088b",
  //         name: "Barite",
  //         category: "Elementary flows/Emission to water/ocean",
  //         flowType: "ELEMENTARY_FLOW",
  //         refUnit: "kg"
  //       },
  //       isInput: false
  //     },
  //     {
  //       flow: {
  //         "@type": "Flow",
