Methods

Evaluate()

Speculates possible types for an expression. If the result { T.A, T.B } is returned, then the result is to be interpreted as "A or B".

public abstract IEnumerable<T> Evaluate()

Returns

IEnumerable<T>

FlattenAssoc<U>(U)

For the given associative infix expression type, recursively unfolds that type and any intermediate grouping expressions, returning a sequence of expressions on which the infix operator acts left to right.

public static IEnumerable<IExpression<T>> FlattenAssoc<U>(U u) where U : InfixExpression<T>

Parameters

u U

Returns

IEnumerable<IExpression<T>>

Type Parameters

U

Print()

Reconstructs the original string representation of the expression

public string Print()

Returns

string

Validate(ExpressionValidator<T>)

Validates whether the expression is structurally and semantically valid and aggregates any errors using the provided expression validator.

public abstract bool Validate(ExpressionValidator<T> validator)

Parameters

validator ExpressionValidator<T>

The validator to use to aggregate errors.

Returns

bool

Whether the expression is valid or not.
