Nested Classes

Modifier and Type	Interface	Description
static class	Expression.AssertionExpression<E>	A non-consuming expression that matches a token against a property of the text, such as the start or end of a line.
static class	Expression.BaseExpression<E>	An expression with no subexpression that is evaluated against a token using the supplied delegate.
static class	Expression.EndAssertion<E>	A non-consuming expression that matches the end of a line.
static class	Expression.MatchingGroup<E>	Represents a matching group that is referred to by order number.
static class	Expression.MinMax<E>	A minimum to maximum number of occurrences of the enclosed expression.
static class	Expression.NamedGroup<E>	Represents a matching group that is referred to by name.
static class	Expression.NonMatchingGroup<E>	Represents a non-matching group.
static class	Expression.Option<E>	Zero or one of the enclosed expression.
static class	Expression.Or<E>	Disjunction of two experssions.
static class	Expression.Plus<E>	One or more of the enclosed expression.
static class	Expression.Star<E>	Kleene-star: zero or more of the enclosed expression.
