rclpy.validate_namespace module

rclpy.validate_namespace.validate_namespace(namespace: str) → Literal[True]

Validate a given namespace, and raise an exception if it is invalid.

Unlike the node constructor, which allows namespaces without a leading ‘/’ and empty namespaces “”, this function requires that the namespace be absolute and non-empty.

If the namespace is invalid then rclpy.exceptions.InvalidNamespaceException will be raised.

Parameters:

namespace – namespace to be validated

Returns:

True when it is valid

Raises:

InvalidNamespaceException: when the namespace is invalid
