Hands-On Design Patterns and Best Practices with Julia

Recognizing the implicit interface of an object

Before we dive into the specific patterns, let's first take a quick detour and discuss how and why we have a problem in the first place.

Suppose that we have defined a data type called Simulation to keep track of some scientific experiment data and related statistics. The syntax for it is as follows:

mutable struct Simulation{N}    heatmap::Array{Float64, N}    stats::NamedTuple{(:mean, :std)}end

A Simulation object contains an N-dimensional array of floating-point values and a named tuple of statistical values. For demonstration purposes, we will create a simple function to perform a simulation and create an object, as follows:

using Distributionsfunction simulate(distribution, dims, n)  tp = ntuple(i ...
