.. _auto_definetable_replace_curve_by_value:

*REPLACE THE CURVE THAT MATCHES THE VALUE OF THE DEFINE TABLE*
==============================================================

Looks up a key value inside a define-table and replaces the associated curve with a new curve, returning the updated table. Use this worker when you need to swap out a single curve entry in a value-keyed lookup table without rebuilding the entire table.

When to use

Classification: **process**.

Inputs
------

.. list-table::
   :header-rows: 1
   :widths: 20 20 20 20 20 20

   * - Label
     - ID
     - Type
     - Default
     - Required
     - Description
   * - Define Table
     - dt1
     - define_table
     - —
     - 
     - The input define-table containing value-to-curve pairs; the worker searches this table for the entry matching the supplied value and replaces its curve.
   * - Value
     - value
     - scalar
     - —
     - 
     - Scalar key used to locate the target row in the define-table; must match one of the table's existing key values exactly.
   * - Curve
     - curve
     - vector
     - —
     - 
     - The replacement curve (x-y vector) that will be written into the define-table at the row identified by the supplied value.

Outputs
-------

.. list-table::
   :header-rows: 1
   :widths: 20 20 20 20

   * - Label
     - ID
     - Type
     - Description
   * - Define Table
     - define_table
     - define_table
     - Updated define-table identical to the input except that the curve paired with the matching value has been replaced by the new curve.
