During running a simulation, one of the most important but annoying part is recording and processing the changing values of state. This package provides "recorded" types, changes of which will be recorded automatically.
Note: There are huge changes between v0.3 and v0.4.
You can not load and process data of v0.3 with v0.4.
This is a registered package, it can be installed with the add command in
the Pkg REPL:
pkg> add RecordedArrays
julia> using RecordedArrays # load this package
julia> c = ContinuousClock(3); # define a clock
julia> v = recorded(DynamicEntry, c, [0, 1]) # create a recorded array with the clock
2-element recorded(::Vector{Int64}):
0
1
julia> v + v # math operations work as normal array
2-element Vector{Int64}:
0
2
julia> v .* v # broadcast works as normal array as well
2-element Vector{Int64}:
0
1
julia> increase!(c, 1) # when time goes and array changes, increase the define clock firstly
1
julia> v[1] += 1 # change array's element
1
julia> increase!(c, 1) # when time goes and array changes, increase the define clock firstly
2
julia> push!(v, 1) # push a new element
3-element recorded(::Vector{Int64}):

julia> es = getentries(v) # view recorded changes
3-element Vector{DynamicEntry{Int64, Int64}}:
DynamicEntry{Int64, Int64}([0, 1], [0, 1])
DynamicEntry{Int64, Int64}([1], [0])
DynamicEntry{Int64, Int64}([1], [2])
julia> es[1] # the changes of the first element of `v`, which changed to 1 at `t=1`
DynamicEntry{Int64, Int64} with timestamps:

julia> gettime(es[1], 0:2) # get the value of the first element at time 0, 1 and 2
