RegexASTSubtreeRootNode

java.lang.Object
- com.oracle.truffle.regex.tregex.parser.ast.RegexASTNode
- - com.oracle.truffle.regex.tregex.parser.ast.Term
  - - com.oracle.truffle.regex.tregex.parser.ast.RegexASTSubtreeRootNode

All Implemented Interfaces:

AbstractState<Term,ASTTransition>, RegexASTVisitorIterable, JsonConvertible

Direct Known Subclasses:

AtomicGroup, LookAroundAssertion, RegexASTRootNode
```
public abstract class RegexASTSubtreeRootNode
extends Term
implements RegexASTVisitorIterable
```
A common supertype to the root node, lookahead and lookbehind assertions and atomic groups. Every AST subtree contains a Group which contains the syntactic subtree, as well as a MatchFound node, which is needed for NFA-like traversal of the AST, see NFATraversalRegexASTVisitor.
