Attributes

category class-attribute instance-attribute

category: FlowNodeInputCategory | None = None

Specifies how input data flows between iterations in a DoWhile loop.

• LoopCondition - Controls whether the loop continues by evaluating condition expressions against the input data. Use this category to define the condition that determines if the loop should continue.

• ReturnValueToLoopStart - Defines data to pass back to the start of the loop's next iteration. Use this category for variables that you want to update for each loop iteration.

• ExitLoop - Defines the value that's available once the loop ends. Use this category to expose loop results to nodes outside the loop.

expression class-attribute instance-attribute

expression: str = field(repr=False)

An expression that formats the input for the node. For an explanation of how to create expressions, see Expressions in Prompt flows in Amazon Bedrock.

name instance-attribute

name: str

Specifies a name for the input that you can reference.

type instance-attribute

type: FlowNodeIODataType

Specifies the data type of the input. If the input doesn't match this type at runtime, a validation error will be thrown.
