DependableTrait

class aws_cdk.core.DependableTrait

Bases: object

Trait for IDependable.

Traits are interfaces that are privately implemented by objects. Instead of showing up in the public interface of a class, they need to be queried explicitly. This is used to implement certain framework features that are not intended to be used by Construct consumers, and so should be hidden from accidental use.

Example:

# Example automatically generated. See https://github.com/aws/jsii/issues/826
# Usage
roots = DependableTrait.get(construct).dependency_roots

# Definition
class TraitImplementation(DependableTrait):
    def __init__(self):
        self.dependency_roots = [construct_a, construct_b, construct_c]
DependableTrait.implement(construct, TraitImplementation())
