.. _auto_curves_iterator:

*ITERATOR*
==========

Iterates over a collection of curves and applies a configurable set of named operations to each one in sequence. Use this worker when you need to batch-process or transform multiple curves with the same pipeline of operations inside a workflow loop.

When to use
-----------

Classification: **process**.

Tagged: ``batch``, ``bulk``, ``curves``, ``iterator``, ``loop``, ``transform``.

Inputs

   * - Curves
     - curves
     - vector
     - —
     - 
     - Collection of input curves to iterate over; accepts multiple curve objects (e.g. time-history or X-Y pairs) that will each be processed by the specified operations — leave empty to pass curves dynamically from an upstream worker.
   * - Operations
     - operations
     - textarea
     - —
     - 
     - Newline-separated list of operations to apply to each curve, where each line is a key=value or key=value,value,… entry defining the operation name and its parameters (e.g. 'scale=2.0' or 'filter=butterworth,100').

Outputs
