A UnaryOperator represents a single unary operation on an expression. The operation type is stored as a tokens::OperatorToken enumerated type on the node. AX grammar guarantees that this token will only every be a valid unary operator token type when initialized by the parser. More...

Public Member Functions | |
UnaryOperator (Expression *expr, const tokens::OperatorToken op) | |
Construct a new UnaryOperator with a given tokens::OperatorToken and a valid expression, transferring ownership of the expression to the UnaryOperator and updating parent data on the expression. More... | |
UnaryOperator (Expression *expr, const std::string &op) | |
Construct a new UnaryOperator with a string, delegating construction to the above UnaryOperator constructor. More... | |
UnaryOperator (const UnaryOperator &other) | |
Deep copy constructor for a UnaryOperator, performing a deep copy on the underlying expressions, ensuring parent information is updated. More... | |
~UnaryOperator () override=default | |
UnaryOperator * | copy () const override final |
The deep copy method for a Node. More... | |
NodeType | nodetype () const override |
Virtual method for accessing node type information. More... | |
const char * | nodename () const override |
Virtual method for accessing node name information. More... | |
const char * | subname () const override |
Virtual method for accessing node name information. More... | |
const Expression * | basetype () const override |
Virtual method for accessing a node's base class. Note that if this is called explicitly on an instance of ast::Node (the top most base class) a nullptr is returned. This is primarily used by the Visitor to support hierarchical visits. More... | |
size_t | children () const override final |
Virtual method for accessing child information. Returns the number of children a given AST node owns. More... | |
const Expression * | child (const size_t i) const override final |
Virtual method for accessing child information. Returns a const pointer to a child node at the given index. If the index is out of range, a nullptr is returned. More... | |
bool | replacechild (const size_t i, Node *node) override final |
Virtual method that attempted to replace a child at a given index with a provided node type. More... | |
tokens::OperatorToken | operation () const |
Query the type of unary operation held on this node. More... | |
const Expression * | expression () const |
Access a const pointer to the UnaryOperator expression as an abstract expression. More... | |
Name/Type | |
template<typename NodeT > | |
bool | isType () const |
Query whether or not this node is of a specific (derived) type. This method should be used to check if a node is of a particular abstract type. When checking concrete types, it's generally more efficient to check the return value of Node::nodetype() More... | |
Child Queries | |
int64_t | childidx () const |
Returns the child index of this node in relation to its parent, or -1 if no valid index is found (usually representing the top most node (i.e. Tree) More... | |
Replacement | |
bool | replace (Node *node) |
In place replacement. Attempts to replace this node at its specific location within its Abstract Syntax Tree. On a successful replacement, this node is destroyed, the provided node is inserted in its place and ownership is transferred to the parent node. No further calls to this node can be made on successful replacements. More... | |
Parent | |
const Node * | parent () const |
Access a const pointer to this nodes parent. More... | |
void | setParent (Node *parent) |
Set this node's parent. This is used during construction of an AST and should not be used. More... | |
