MethodEditor

The MethodEditor module is a key component of the T-reX tool, offering functionalities to manage methods related to waste and material footprints in a project. This module is instrumental in adding, deleting, and checking methods within the context of environmental impact assessments.

Function Summary

`AddMethods`: This function adds new methods to a project based on entries in a custom biosphere database. It is useful for incorporating specific waste and material footprint methodologies into the project’s analysis framework.
`DeleteMethods`: This function removes specific methods from a project, particularly those associated with waste and material footprints, aiding in maintaining the relevance and accuracy of the project’s methodological toolbox.
`CheckMethods`: This function lists and checks the methods in a project, focusing on those linked to waste and material footprints, ensuring that the methods are correctly implemented and aligned with the project’s objectives.

Important Code Snippets

Function to Add Methods to a Project:

def AddMethods():
    # ... snippet to show structure of method keys added ...

    # Assign characterization factor based on type
    ch_factor = -1.0 if m_type == "waste" else 1.0

    # Assign method key and description based on type
    if m_type == "waste":
        name_combined = m_code.split(" ")[0] + " combined"
        method_key = (
            "T-reX",
            "Waste: " + name_combined,
            m_code,
        )
        description = "For estimating the waste footprint of an activity"
    else:
        method_key = ("T-reX", "Demand: " + m_code, m_code)
        description = "For estimating the material demand footprint of an activity"

    # ... end snippet ...

Function to Delete Methods from a Project:

def DeleteMethods():
    # Implementation of the function

Function to Check Methods in a Project:

def CheckMethods():
    # ... snippet to show how methods are accessed ...

    methods_T_reX = [
        x for x in list(bd.methods) if "WasteAndMaterial Footprint" == x[0]
    ]

    for m in methods_T_reX:
        method = bd.Method(m)
        print(method.load())
        print(method.metadata)

    print(len(methods_T_reX))

    # ... end snippet ...
