BinaryComponentLink

class glue.core.component_link.BinaryComponentLink(left, right, op)

Bases: ComponentLink

A ComponentLink that combines two inputs with a binary function

Parameters:

leftComponentID, ComponentLink, or number

The first input argument.

rightComponentID, ComponentLink, or number

The second input argument.

opfunc

A function with two inputs that works on numpy arrays.

The ComponentLink represents the logic of applying `op` to the

data associated with the inputs `left` and `right`.

Methods Summary

compute(data[, view])	For a given data set, compute the component comp_to given the data associated with each comp_from and the using function
replace_ids(old, new)	Replace all references to an old ComponentID with references to new.

Methods Documentation

compute(data, view=None)

For a given data set, compute the component comp_to given the data associated with each comp_from and the using function

This raises an glue.core.exceptions.IncompatibleAttribute if the data set doesn’t have all the ComponentIDs needed for the transformation

Parameters:

data~glue.core.data.Data

The data set to use.

viewslice or tuple, optional

Optional view (e.g. slice) through the data to use.

Returns:

result

The data associated with comp_to component

replace_ids(old, new)

Replace all references to an old ComponentID with references to new.

Parameters:

oldComponentID

ComponentID to replace.

newComponentID

ComponentID to replace with.
