## Functions

OPENVDB_AX_API bool | usesAttribute (const ast::Node &node, const std::string &name, const tokens::CoreType type=tokens::UNKNOWN)
| Returns whether or not a given branch of an AST reads from or writes to a given attribute.
OPENVDB_AX_API bool | writesToAttribute (const ast::Node &node, const std::string &name, const tokens::CoreType type=tokens::UNKNOWN)
| Returns whether or not a given branch of an AST writes to a given attribute.
OPENVDB_AX_API bool | callsFunction (const ast::Node &node, const std::string &name)
| Returns whether or not a given branch of an AST calls a function.
OPENVDB_AX_API void | catalogueVariables (const ast::Node &node, std::vector< const ast::Variable * > *readOnly, std::vector< const ast::Variable * > *writeOnly, std::vector< const ast::Variable * > *readWrite, const bool locals=true, const bool attributes=true)
| todo
OPENVDB_AX_API void | catalogueAttributeTokens (const ast::Node &node, std::vector< std::string > *readOnly, std::vector< std::string > *writeOnly, std::vector< std::string > *readWrite)
| Parse all attributes into three unique vectors which represent how they are accessed within the syntax tree. Read only attributes are stored within the 'readOnly' container (for example.
OPENVDB_AX_API void | attributeDependencyTokens (const ast::Tree &tree, const std::string &name, const tokens::CoreType type, std::vector< std::string > &dependencies)
| Populate a list of attribute names which the given attribute depends on.
template<typename NodeT, typename OpT>
void | visitNodeType (const ast::Node &node, const OpT &op)
| For an AST node of a given type, search for and call a custom const operator() which takes a const reference to every occurrence of the specified node type.
template<typename NodeT, typename ContainerType = std::vector<const NodeT*>>
void | collectNodeType (const ast::Node &node, ContainerType &array)
| Visit all nodes of a given type and store pointers to them in a provided compatible container.
template<typename NodeTypeList, typename ContainerType = std::vector<const Node*>>
void | collectNodeTypes (const ast::Node &node, ContainerType &array)
| Visit all nodes of the given types and store pointers to them in a container of base ast::Node pointers.
OPENVDB_AX_API void | linearize (const ast::Node &node, std::vector< const ast::Node * > &list)
| Flatten the provided AST branch into a linear list using post order traversal.
OPENVDB_AX_API const ast::Variable * | firstUse (const ast::Node &node, const std::string &token)
OPENVDB_AX_API const ast::Variable * | lastUse (const ast::Node &node, const std::string &token)
