Method: Generex<T, TCombined> ThenExpect<TCombined>(Generex<T>, Func<TResult, GenerexMatch<T>, TCombined>, Func<GenerexMatch<T, TResult>, Exception>)

• Declared in: RT.Generexes.Generex<T, TResult>

Declaration

public Generex<T, TCombined> ThenExpect<TCombined>(
    Generex<T> expectation,
    Func<TResult, GenerexMatch<T>, TCombined> selector,
    Func<GenerexMatch<T, TResult>, Exception> exceptionGenerator
)

Summary

Returns a regular expression that matches this regular expression, then attempts to match the specified other regular expression and throws an exception if the second regular expression fails to match; otherwise, a result object is generated from the current result object and the second match.

Generic type parameters

TCombined

Type of the result object for the resulting regular expression.

Parameters

Generex<T>	expectation	The regular expression that is expected to match after the current one.
Func<TResult, GenerexMatch<T>, TCombined>	selector	A selector which, in case of a match, generates the new result given the current result object and the match of the expectation.
Func<GenerexMatch<T, TResult>, Exception>	exceptionGenerator	A selector which, in case of no match, generates the exception object to be thrown.

Returns

The resulting regular expression.

Remarks

Regular expressions created by this method cannot match backwards. The full set of affected methods is listed at GenerexBase<T, TMatch, TGenerex, TGenerexMatch>.Then<TOtherGenerex, TOtherMatch, TOtherGenerexMatch>(Func<TGenerexMatch, GenerexBase<T, TOtherMatch, TOtherGenerex, TOtherGenerexMatch>>).
