6.1. Component — Component base class

A component is just something that has a name to identify it and that stores slot objects. Usually, the slots are used for providing inputs to the component which are used to generate outputs that can also be accessed via slots. The component is then the ‘black box’ that computes the output from the input.

class Component(name = "", auto_insert = True)

name is the name of the component which can be used to identify it.

The component will be inserted into the scene automatically if auto_insert is set to True.

name

The component’s name. You can read and write this attribute.

addSlot(name, slot)

hasSlot(name)

Check if a slot with a particular name does exist.

iterSlots()

Return an iterator that iterates over all slot names.

numSlots()

Return the number of slots in this component.

removeSlot(name)

Remove the slot with the given name. A KeyError exception is thrown if there is no slot with the specified name.
