Class	Description
BackReference	A reference to the contents of a previously matched capturing group.
CalcASTPropsVisitor	This visitor computes various properties of RegexAST and its RegexASTNodes, in two passes.
CharacterClass	A Term that matches characters belonging to a specified set of characters.
Group	Groups are the top-most elements of regular expression ASTs.
GroupBoundaries	Objects of this class represent the capture group boundaries traversed in a single NFAStateTransition or ASTTransition.
InnerLiteral	Represents a literal string inside the regular expression that can be searched for before starting the actual regular expression matcher.
LookAheadAssertion	An assertion that succeeds depending on whether another regular expression can be matched at the current position.
LookAroundAssertion	An assertion that succeeds depending on whether or not text surrounding the current position matches a given regular expression.
LookAroundIndex
LookBehindAssertion	An assertion that succeeds depending on whether or not text preceding the current position matches a given regular expression.
MatchFound	MatchFound nodes are RegexASTNodes that represent the initial/final states of the non-deterministic finite state automaton generated from the regular expression.
PositionAssertion	An assertion that succeeds when encountered at the beginning or at the end of the string we are searching in.
QuantifiableTerm	Roughly corresponds to the goal symbol Atom in the ECMAScript RegExp syntax.
RegexAST
RegexASTNode
RegexASTRootNode	Root node of every AST.
RegexASTSubtreeRootNode	A common supertype to the root node and look-ahead and look-behind assertions.

Term	A common supertype for all RegexASTNodes except Sequences.
