Detailed Description

Enum type node.

This class represents enum types. Note that it does not represent the definition of the enums, but just an instant of the type. Any time the source refers to one of the enum constants, or has a variable or parameter that accepts the enum, this is the type associated. The actual definition resides in an suespecNode.

The NodeType is Enum.

Constructor & Destructor Documentation

enumNode::enumNode (  const Coord    coord = Coord::Unknown )

Create new enum type. The new enum type has no tag and doesn't refer to any definition. Use the sueNode::spec() methods to get and set the reference to the definition, which also contains the name. Parameters: coord  the location of the construct in the source file.

enumNode::enumNode (  idNode *    id, decl_list *    values, const Coord    enum_coord, const Coord    left_coord, const Coord    the_right_coord )

Create a new enum during parsing.

enumNode::~enumNode (    )  [virtual]

Destroy a enumNode. Warning: Do not use the destructors to delete AST nodes. Instead, rely on the node garbage collector.

Member Function Documentation

Node * enumNode::change (  Changer &    the_changer, bool    redispatch = false )  [virtual]

Dispatch a Changer. This abstract method works much the walker, but allows the tree to be changed. Parameters: the_changer  the specific Changer object to use. redispatch  pass true to revisit parts of the tree that have changed. Reimplemented from Node.

virtual Node* enumNode::clone (    )  const [inline, virtual]

Clone the input node. This is not a "deep" clone, so be careful. For a deep clone, use the clone_changer class. Returns: a shallow copy of the node (no subtrees are copied). Reimplemented from Node.

virtual bool enumNode::is_arithmetic (    )  const [inline, virtual]

Reimplemented from typeNode.

virtual bool enumNode::is_int (    )  const [inline, virtual]

Reimplemented from typeNode.

virtual bool enumNode::is_integer (    )  const [inline, virtual]

Reimplemented from typeNode.

virtual bool enumNode::is_scalar (    )  const [inline, virtual]

Reimplemented from typeNode.

void enumNode::visit (  Visitor *    the_visitor )  [virtual]

Dispatch a Visitor. This abstract method is the entry point for the visitor design pattern. Each node subclass defines a visit() method that calls the appropriate at_ method in the visitor. For more information see the Visitor documentation. Parameters: the_visitor  the specific Visitor object to use. Reimplemented from Node.

void enumNode::walk (  Walker &    the_walker )  [virtual]

Dispatch a Walker. This abstract method works much like the visitor, but instead walks the entire underlying subtree calling the appropriate at_ method at each node. For more information see the Walker documentation. Parameters: the_walker  the specific Walker object to use. Reimplemented from Node.
