Autonomy Software C++ 24.5.1
Welcome to the Autonomy Software repository of the Mars Rover Design Team (MRDT) at Missouri University of Science and Technology (Missouri S&T)! API reference contains the source code and other resources for the development of the autonomy software for our Mars rover. The Autonomy Software project aims to compete in the University Rover Challenge (URC) by demonstrating advanced autonomous capabilities and robust navigation algorithms.

DuckDB 1.3. introduced a new lambda syntax: lambda x, y: x + y. The new syntax resolves any ambiguity with the JSON arrow operator. Currently, we're still using a LambdaExpression for both cases.
| vector< reference< const ParsedExpression > > duckdb::LambdaExpression::ExtractColumnRefExpressions | ( | string & | error_message | ) | const |
Returns a vector to the column references in the LHS expression, and fills the error message, if the LHS is not a valid lambda parameter list
|
overridevirtual |
Convert the Expression to a String.
Implements duckdb::BaseExpression.
|
overridevirtual |
Creates a hash value of this expression. It is important that if two expressions are identical (i.e. Expression::Equals() returns true), that their hash value is identical as well.
Implements duckdb::BaseExpression.
|
overridevirtual |
Create a copy of this expression.
Implements duckdb::ParsedExpression.
|
overridevirtual |
Reimplemented from duckdb::ParsedExpression.
| unique_ptr<ParsedExpression> duckdb::LambdaExpression::lhs |
The LHS of a lambda expression or the JSON "->"-operator. We need the context to determine if the LHS is a list of column references (lambda parameters) or an expression (JSON)
