Get the annotations list. This method returns a modifiable reference to the list of annotations on the node. Users can add new annotations, search for annotations, or remove annotations. Users are responsible for ensuring that every element of the annotation list points to a valid annotation. In particular, no element should be NULL.

|
Return the base data type of a node. This method differs from the Node::type() method in two respects. First, it follows some of the simple type inferences. For example, calling it on an idNode will return the type of its declaration. Second, the boolean argument indicates whether or not to follow typedef links.
Reimplemented in declNode, procNode, typeNode, tdefNode, exprNode, idNode, commaNode, callNode, blockNode, and exprstmtNode. |
|
Dispatch a Changer. This abstract method works much the walker, but allows the tree to be changed.
Implements Node. |
|
Clone the input node. This is not a "deep" clone, so be careful. For a deep clone, use the ref_clone_changer class.

|
Set the source location. This location should indicate the position in the source text that this Node represents, or Coord::Unknown if it does not represent any node in the source text. It is not common to set the source location of a node. Currently, only the compiler error messages actually make use of it.
Definition at line 243 of file ast.h. References Node::_coord. |
|
Get the source location. The Coord class holds a location in the input source (file, line, position). During parsing, each AST node created records the position of the source text that it represents. However, subsequent phases may create or change nodes, so no guarantee is given about how the source location corresponds to the original source text.
Definition at line 230 of file ast.h. References Node::_coord. |
|
Run the dataflow analyzer. Each subclass overrides this method to define it's semantics for dataflow analysis. It alters the input flow value to reflect the effect of the node within the given flow problem, calling dataflow() on it's subtrees as necessary. See the dataflow analysis documentation for more information.
Implements Node. |
|
Call base_type() with the argument true.
|
|
Call base_type() with the argument false.
|
|
Set the "gen" flow value. This value is used in dataflow analyses to store information that is generated at this node. Note that each node has exactly one "gen" flow value. In order to set the flow value to be empty, call this method with a value of NULL.

|
Get the "gen" flow value. This value is used in dataflow analyses to store information that is generated at this node. Note that each node has exactly one "gen" flow value.

|
Set the "kill" flow value. This value is used in dataflow analyses to store information that is killed at this node. Note that each node has exactly one "kill" flow value. To set the flow value to be empty, call this method with a value of NULL.

|
Get the "kill" flow value. This value is used in dataflow analyses to store information that is killed at this node. Note that each node has exactly one "kill" flow value.

Generate C code. Each subclass overrides this method to define how to produce the output C code. To use this method, pass an output_context and a null parent.
Implements Node. |
|
|
|
Output a statement.
Implements stmtNode. |
|
Set the parenthesized boolean. This boolean determines whether this expression will be parenthesized in the output. Note that that the parentheses will always be added when they are needed to disambiguate the output. This variable only controls the use of "un-necessary" parentheses.
Definition at line 262 of file ast.h. References Node::_parenthesized. |
|
Get the parenthesized boolean.
Definition at line 250 of file ast.h. References Node::_parenthesized. |
|
Report node count statistics. The code can be configured to gather statistics about node usage according to type. This method prints the current state of that accounting information to standard out. |
|
Get the node type. This has nothing to do with types in the source code. It indicates what kind of AST node this is (e.g., a unary expression node or a while node).

|
Return the node data type. This method returns the C data type of a node. Several different kinds of nodes contain typeNode pointers. This method is just a unified way to access them. It does not attempt to compute the type, it just returns whatever typeNode pointer resides on the node. The subclasses that have types return them, and the others return null.
Reimplemented in declNode, typeNode, exprNode, and operandNode. |
|
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.
Implements Node. |
|
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.
Implements Node. |
