class Attribute:
|
|
"""
|
|
A class that represents named attributes, providing methods for accessing and storing them.
|
|
|
|
Create an attribute with a name, data type, and optional domain.
|
|
```python
|
|
height_level = Attribute(
|
|
"height_level",
|
|
NamedAttribute.DataType.FLOAT,
|
|
StoreNamedAttribute.Domain.POINT # optional
|
|
)
|
|
```
|
|
|
|
Access the attribute value by calling the class instance.
|
|
```python
|
|
height_level()
|
|
```
|
|
|
|
Store a value for the named attribute on some geometry with `store(...)`.
|
|
```python
|
|
height_level.store(geometry, value)
|
|
```
|
|
|
|
Check if the attribute exists on some geometry with `exists()`.
|
|
```python
|
|
selection = height_level.exists()
|
|
```
