An enumerated list of node types for all concrete node types. These can be used for faster evaluation of a given concrete node using the virtual function table via Node::nodetype() rather than performing a dynamic_cast/calling Node::isType. More... | |

Public Member Functions | |
StatementList () | |
Construct a new StatementList with an empty list. More... | |
StatementList (Statement *statement) | |
Construct a new StatementList with a single statement, transferring ownership of the statement to the statement list and updating parent data on the statement. If the statement is a nullptr, it is ignored. More... | |
StatementList (const std::vector< Statement * > &statements) | |
Construct a new StatementList from a vector of statements, transferring ownership of all valid statements to the statement list and updating parent data on the statement. Only valid (non null) statements are added to the statement list. More... | |
StatementList (const StatementList &other) | |
Deep copy constructor for a StatementList, performing a deep copy on every held statement, ensuring parent information is updated. More... | |
~StatementList () override=default | |
StatementList * | copy () const override |
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 Statement * | 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 Statement * | 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... | |
size_t | size () const |
Alias for StatementList::children. More... | |
void | addStatement (Statement *stmnt) |
Adds a statement to this statement list, transferring ownership to the statement list and updating parent data on the statement. If the statement is a nullptr, it is ignored. 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... | |
Concrete AST nodes.
A StatementList is derived from a Statement and comprises of combinations of multiple statements. This could represent either a list of statements of different types but in practice will likely represent a ',' separated list of the same type i.e. 'int i = 1, j = 1;'.
