### *class* RAInletsOutletsCollection

Rocky PrePost Scripting wrapper for the collection of particle inputs in a project.

This wrapper corresponds to the “Inputs” item in the project’s data tree. To retrieve the [`RAInletsOutletsCollection`](#generated.RAInletsOutletsCollection) from a [`RAStudy`](RAStudy.md#generated.RAStudy), use:

```python
input_collection = study.GetParticleInputCollection()

```

Instances of the [`RAInletsOutletsCollection`](#generated.RAInletsOutletsCollection) class act as regular Python lists, and can be iterated on, accessed via index, etc:

```python
input_1 = input_collection.New()
input_2 = input_collection[1]
del input_collection[0]
for input in input_collection:
    print(input.GetName())

```

Items in this list are of type [`RAParticleInlet`](RAParticleInlet.md#generated.RAParticleInlet).

**Methods:**
