StreamingBatchFlow<TIn, TOut> class
A flow that processes a batch of items sequentially through a series of nodes.
StreamingBatchFlow is designed for scenarios where a collection of items
needs to be processed in a pipeline fashion. Each node in the flow receives
the batch of items, performs an operation, and passes the modified batch to
the next node.
The flow is asynchronous, leveraging Dart's Future to handle operations
that may not complete immediately.

Methods
-
clone(
) → StreamingBatchFlow< TIn, TOut> -
Creates a deep copy of this AsyncFlow.
override
-
copy<
T extends Flow> ([T factory()?]) → T -
Creates a deep copy of this Flow.
inherited
-
createInstance(
) → BaseNode -
Creates a new instance of Flow.
inherited
-
exec(
dynamic prepResult) → Future -
The main execution logic for the flow.
inherited
-
execAsync(
dynamic prepResult) → Future -
Async execution logic - calls orchAsync.
inherited
-
execFallbackAsync(
dynamic prepResult, Exception error) → Future -
Async fallback logic when execAsync fails.
inherited
-
getNextNode(
BaseNode curr, dynamic action) → BaseNode? -
Gets the next node based on the current node and action.
inherited
-
next(
BaseNode node, {String action = 'default'}) → BaseNode -
Defines the next node in the sequence.
inherited
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
orch(
Map< String, dynamic> ? params, int? maxSteps]) → Future -
Core orchestration method that executes the flow graph.
inherited
-
orchAsync(
Map< String, dynamic> ? params, int? maxSteps]) → Future -
Async orchestration method that executes the flow graph.
inherited
-
post(
dynamic prepResult, dynamic execResult) → Future -
Post-processing logic after
exec.inherited -
postAsync(
dynamic prepResult, dynamic execResult) → Future -
Async post-processing logic after execAsync.
inherited
-
prep(
) → Future -
Pre-processing logic before
exec.inherited -
prepAsync(
) → Future -
Async pre-processing logic before orchAsync.
inherited
-
run(
) → Future -
Executes the streaming batch flow.
override
-
runAsync(
) → Future -
Async-specific run method for AsyncFlow.
inherited
-
start(
BaseNode node) → BaseNode -
Sets the starting
nodefor the flow. This is the entry point for the execution of the flow.inherited -
toString(
) → String -
A string representation of this object.

action.inherited -
operator ==(
Object other) → bool -
The equality operator.
inherited
-
operator >>(
BaseNode other) → BaseNode -
