BinaryComponentLink

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

Bases: glue.core.component_link.ComponentLink

A ComponentLink that combines two inputs with a binary function

Parameters

• left – The first input argument. ComponentID, ComponentLink, or number

• right – The second input argument. ComponentID, ComponentLink, or number

• op – A function with two inputs that works on numpy arrays

The CompoentLink represents the logic of applying op to the data associated with the inputs left and right.

Methods Summary

compute(self, 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(self, old, new)	Replace all references to an old ComponentID with references to new

Methods Documentation

compute(self, 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

viewNone or slice or tuple

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

Returns

result

The data associated with comp_to component

replace_ids(self, old, new)

Replace all references to an old ComponentID with references to new

Parma old

ComponentID to replace

Parameters

new – ComponentID to replace with
