# IResourcePolicyFactory

Factory interface for creating IResourceWithPolicyV2 instances from constructs.

Implementations of this interface are registered in the DefaultPolicyFactories registry
and enable automatic resource policy support for CloudFormation resources. When a grant
operation is performed, the factory converts L1 constructs into resources that support
resource-based policies.

Factories are typically registered during static initialization and associated with
specific CloudFormation resource types (e.g., 'AWS::DynamoDB::Table'). The CDK's grant
system uses these factories to determine whether a resource supports resource policies
and to create the appropriate wrapper when needed.
