Description

Base class for all C/C++ syntax tree classes.

The syntax tree is the result of the syntactic analysis of the input source code representing its syntactic structure according to the accepted grammar (see class Syntax).

Objects of this class and classes derived from this class are created by the tree builder component of Puma during the parse process. A syntax tree shall be destroyed using the tree builder that has created it by calling its method Builder::destroy(CTree*) with the root node of the syntax tree as its argument.

The navigation in the syntax tree is done using the methods CTree::Parent(), CTree::Sons(), and CTree::Son(int) const. In a syntax tree "sons" are understood as the syntactic child nodes of a syntax tree node, whereas "daughters" are understood are their semantic child nodes.

Another way to traverse a syntax tree is to implement an own tree visitor based on class Puma::CVisitor. This is recommended especially for larger syntax trees.

A syntax tree node can be identified by comparing its node name with the node identifier of the expected syntax tree node:

if (node->NodeName() == Puma::CT_BinaryExpr::NodeId()) ...
static const char * NodeId()
Get the identifier for this node type.

Based on the syntax tree further semantic analyses can be performed. Semantic information, like scope, value, type, and object information, is linked into the syntax tree. It can be accessed using the methods CTree::SemScope(), CTree::SemValue(), and CTree::SemObject(). Some nodes provide short-cuts to the semantic type and value information by implementing the methods CTree::Type() and CTree::Value().

The information of the syntax tree can be used to perform high-level transformations of the source code (see class ManipCommander).
