baybe.parameters.selectors.to_parameter_selector(x: str | type[Parameter] | Collection[str] | Collection[type[Parameter]] | ParameterSelectorProtocol, /)

Convert shorthand notations to parameter selectors.

Convenience converter that allows users to specify parameter selectors using simpler types:

• A callable (i.e., an existing selector or any object satisfying ParameterSelectorProtocol) is passed through unchanged.

• A single string is interpreted as a parameter name and wrapped into a NameSelector.

• A single Parameter subclass is wrapped into a TypeSelector.

• A collection of strings is converted to a NameSelector.

• A collection of Parameter subclasses is converted to a TypeSelector.

Parameters:

x (str | type[Parameter] | Collection[str] | Collection[type[Parameter]] | ParameterSelectorProtocol) – The object to convert.

Return type:

ParameterSelectorProtocol

Returns:

The corresponding parameter selector.

Raises:

TypeError – If the input cannot be converted to a parameter selector.
