Public Functions

const NodeTypeInfo &get_type_info() const

Returns the NodeTypeInfo for the node’s class. During transition to type_info, returns a dummy type_info for Node if the class has not been updated yet.

Constructs a shape-of operation.

void validate_and_infer_types()

Throws if the node is invalid.
