podpac.algorithm.Arange

class podpac.algorithm.Arange(**kwargs)[source]

Bases: podpac.core.algorithm.algorithm.Algorithm

A simple test node that gives each value in the output a number.

Alternative Constructors

from_definition(definition)

Create podpac Node from a dictionary definition.

from_json(s)

Create podpac Node from a JSON definition.

Methods

__init__(**kwargs)

Do not overwrite me

algorithm(inputs)

Uses np.arange to give each value in output a unique number

create_output_array(coords[, data])

Initialize an output data array

eval(coordinates[, output])

Evalutes this nodes using the supplied coordinates.

eval_group(group)

Evaluate the node for each of the coordinates in the group.

find_coordinates()

Get the available coordinates for the inputs to the Node.

from_url(url)

Create podpac Node from a WMS/WCS request.

get_cache(key[, coordinates])

Get cached data for this node.

has_cache(key[, coordinates])

Check for cached data for this node.

init()

Overwrite this method if a node needs to do any additional initialization after the standard initialization.

load(path)

Create podpac Node from file.

put_cache(data, key[, coordinates, overwrite])

Cache data for this node.

rem_cache(key[, coordinates, mode])

Clear cached data for this node.

save(path)

Write node to file.
