Usage

Identifying a dataset

Reading datasets

Base.read — Function
read(filename::AbstractString, DataCollection; writer::Union{Function, Nothing})

Read the entire contents of a file as a DataCollection.

The default value of writer is self -> write(filename, self).

source
read(io::IO, DataCollection; path::Union{String, Nothing}=nothing, mod::Module=Base.Main)

Read the entirety of io, as a DataCollection.

source
read(dataset::DataSet, as::Type)
read(dataset::DataSet) # as default type

Obtain information from dataset in the form of as, with the appropriate loader and storage provider automatically determined.

This executes this component of the overall data flow:

                 ╭────loader─────╮
                 ╵               ▼
Storage ◀────▶ Data          Information

The loader and storage provider are selected by identifying the highest priority loader that can be satisfied by a storage provider. What this looks like in practice is illustrated in the diagram below.

      read(dataset, Matrix) ⟶ ::Matrix ◀╮

Writing datasets

Base.write — Function
write(dataset::DataSet, info::Any)

TODO write docstring

source

Accessing the raw data

Base.open — Function
open(dataset::DataSet, as::Type; write::Bool=false)

Obtain the data of dataset in the form of as, with the appropriate storage provider automatically selected.

A write flag is also provided, to help the driver pick a more appropriate form of as.

This executes this component of the overall data flow:

                 ╭────loader─────╮
                 ╵               ▼
