finam.adapters

Adapters to transform or interpolate data when passed between modules.

See also book chapter Known FINAM modules for a list of other adapters that are not included in the core package.

Base adapters

Callback(callback)	Transform data using a callback.
Scale(scale)	Scales the input.
ValueToGrid(grid)	Convert a scalar value to a Matrix filled with that value.
GridToValue(func)	Convert a matrix to a scalar value using an aggregation function, e.g. numpy.mean.

Probe adapters

CallbackProbe(callback)

Probe data by calling a callback.

Regridding adapters

RegridNearest([in_grid, out_grid, tree_options])	Regrid data between two grid specifications with nearest neighbour interpolation.
RegridLinear([in_grid, out_grid, ...])	Regrid data between two grid specifications with linear interpolation.

Statistics adapters

Histogram(lower, upper[, bins, density])

Calculates a histogram over grid values.

Time adapters

LinearTime()	Linear time interpolation.
NextTime()	Time interpolation providing the next future value.
PreviousTime()	Time interpolation providing the newest past value.
StackTime()	Stacks all incoming data since the last push.
StepTime([step])	Step-wise time interpolation.
AvgOverTime([step])	Aggregates data over time to form the temporal average over the last pull time step.
SumOverTime([step, per_time, initial_interval])	Aggregates data over time to form the temporal sum (area under curve) over the last pull time step.
DelayFixed(delay)	Delays/offsets the request time by subtracting a fixed offset.
DelayToPush()	Delays/offsets the request time to the last push time if out of range.
DelayToPull([steps, additional_delay])	Delays/offsets the request time to a previous pull time.
TimeCachingAdapter()	Abstract base class for time handling and caching adapters.
