utility:merge collections

Last update: 31.07.2026

Version: 0.0.0

Description

Merges a set of collections into a unique one.

Inputs

This table lists the input pins for this operator. Input pins define the data that the operator requires to perform its operation. Some inputs are required, while others are optional and provide additional configuration. Each parameter is detailed in the sections that follow the table.

Pin number Name Status Expected type(s)
0 collections Required vector<shared_ptr<any_collection>>, any_collection

collections (Pin 0)

  • Required: Yes
  • Expected type(s): vector<shared_ptr<any_collection>>, any_collection

a vector of collections to merge or collections from pin 0 to ...

Outputs

This table lists the output pins for this operator. Output pins provide the results of the operator's computation and can be connected to inputs of other operators or retrieved for further processing. Each output is detailed in the sections that follow the table.

Pin number Name Expected type(s)
0 merged_collections any_collection

merged_collections (Pin 0)

Configurations

This operator supports configuration options that modify its behavior.

mutex

  • Expected type(s): bool
  • Default value: false

If this option is set to true, the shared memory is prevented from being simultaneously accessed by multiple threads.

read_inputs_in_parallel

  • Expected type(s): bool
  • Default value: false

If this option is set to true, the operator's inputs will be evaluated in parallel.

Scripting

This operator can be accessed through scripting interfaces using these identifiers.

Examples

These examples demonstrate how to use this operator in different programming environments. Each example shows how to instantiate the operator, connect the required inputs, and retrieve the output.

C++
#include "dpf_api.h"

ansys::dpf::Operator op("merge::any_collection"); // operator instantiation
op.connect(0, my_collections);
ansys::dpf::AnyCollection my_merged_collections = op.getOutput<ansys::dpf::AnyCollection>(0);
CPython
import ansys.dpf.core as dpf

op = dpf.operators.utility.merge_collections() # operator instantiation
op.inputs.collections1.connect(my_collections1)
op.inputs.collections2.connect(my_collections2)
my_merged_collections = op.outputs.merged_collections()
IPython
import mech_dpf
import Ans.DataProcessing as dpf

op = dpf.operators.utility.merge_collections() # operator instantiation
op.inputs.collections.Connect(my_collections)
my_merged_collections = op.outputs.merged_collections.GetData()
