Interface CAst

  • All Known Implementing Classes:
    CAstImpl, CAstValueImpl
    public interface CAst
    The main interface for creating CAPA Abstract Syntax Trees. This interface provides essentially a factory for creating AST nodes in a tree structure. There is no strong assumption about the meaning of specific nodes; however, the `kind' argument to a makeNode call should be a value from the constants in the CAstNode interface. The other arguments to makeNode calls are child nodes. The structure of the tree is a matter of agreement between providers and consumers of specific trees.
