public class CfnFlow
extends CfnResource
implements IInspectable, ITaggableV2

Creates a prompt flow that you can use to send an input through various steps to yield an output.

You define a flow by configuring nodes, each of which corresponds to a step of the flow, and creating connections between the nodes to create paths to different outputs. You can define the flow in one of the following ways:

• Define a FlowDefinition in the Definition property.
• Provide the definition in the DefinitionString property as a JSON-formatted string matching the FlowDefinition property.
• Provide an Amazon S3 location in the DefinitionS3Location property that matches the FlowDefinition .

If you use the DefinitionString or DefinitionS3Location property, you can use the DefinitionSubstitutions property to define key-value pairs to replace at runtime.

For more information, see How it works and Create a prompt flow in Amazon Bedrock in the Amazon Bedrock User Guide.

Example:

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.bedrock.*;
 Object collector;
 Object input;
 Object iterator;
 Object output;
