Iterate<TSource>(TSource, Func<TSource, TSource>)

Makes a generator that returns iterations of the specified initial element.

public static IGenerator<TSource> Iterate<TSource>(TSource initialElement, Func<TSource, TSource> iterator)

Parameters

initialElement TSource

The initial element.

iterator Func<TSource, TSource>

The iteration function.

Returns

IGenerator<TSource>

IGenerator<TSource>.

Type Parameters

TSource

The type of the source generator.

Remarks

If the iteration function is f and the initial element is x, then the result generator will generate x, f(x), f(f(x)), f(f(f(x))), ...

Exceptions

ArgumentNullException

Iterate<TSource, TSource2>(TSource, IGenerator<TSource2>, Func<TSource, TSource2, TSource>)

Applies a function on the last element to produce the next element. The function takes twp parameters; the second parameter is supplied by a generator.

public static IGenerator<TSource> Iterate<TSource, TSource2>(TSource initialElement, IGenerator<TSource2> parm2, Func<TSource, TSource2, TSource> iterator)

Parameters

initialElement TSource

parm2 IGenerator<TSource2>

iterator Func<TSource, TSource2, TSource>

Returns

IGenerator<TSource>

Type Parameters

TSource

TSource2

Iterate<TSource>(TSource, TSource, Func<TSource, TSource, TSource>)

Makes a generator that uses an iterator function to generate elements.

public static IGenerator<TSource> Iterate<TSource>(TSource initialElement0, TSource initialElement1, Func<TSource, TSource, TSource> iterator)

Parameters

initialElement0 TSource

The first element to generate.

initialElement1 TSource

The second element to generate.

iterator Func<TSource, TSource, TSource>

The iterator function.

Returns

IGenerator<TSource>

Type Parameters

TSource

The type of the t source.

Remarks

The iterator function is applied the last two items generated to produce the next one. The first two elements are provided by the caller. For example,

Iterate(0, 1, (x, y) => x + y);

make a generator that produces the Fibonacci numbers.

Exceptions

ArgumentNullException

Iterate<TSource>(TSource, TSource, TSource, Func<TSource, TSource, TSource, TSource>)

Makes a generator that uses an iterator function to generate elements.

public static IGenerator<TSource> Iterate<TSource>(TSource initialElement0, TSource initialElement1, TSource initialElement2, Func<TSource, TSource, TSource, TSource> iterator)

Parameters

initialElement0 TSource

The first element to generate.

initialElement1 TSource

The second element to generate.

initialElement2 TSource

The third element to generate.

iterator Func<TSource, TSource, TSource, TSource>

The iterator function.

Returns

IGenerator<TSource>

Type Parameters

TSource

The type of the t source.

Remarks

The iterator function is applied the last three items generated to produce the next one. The first three elements are provided by the caller. For example,

Iterate(0, 0, 1, (x, y, z) => x + y + z);

make a generator that produces the Tribonacci numbers.

Exceptions

ArgumentNullException

Iterate<TSource>(TSource, TSource, TSource, TSource, Func<TSource, TSource, TSource, TSource, TSource>)

Makes a generator that uses an iterator function to generate elements.

public static IGenerator<TSource> Iterate<TSource>(TSource initialElement0, TSource initialElement1, TSource initialElement2, TSource initialElement3, Func<TSource, TSource, TSource, TSource, TSource> iterator)

Parameters

initialElement0 TSource

The first element to generate.

The fourth element to generate.

iterator Func<TSource, TSource, TSource, TSource, TSource>

The iterator function.

Returns

IGenerator<TSource>

Type Parameters

TSource

The type of the t source.

Remarks

The iterator function is applied the last four items generated to produce the next one. The first four elements are provided by the caller. For example,

Iterate(0, 0, 0, 1, (x, y, z, w) => x + y + w + z);

make a generator that produces the Tetranacci numbers.

Exceptions

ArgumentNullException
