Compose<Input, Output> class

Compose a series of functions, the output of the previous function in the chain is automatically passed as input to the next function in the chain.

int x2(int a) => a * 2;

/// Compose one input 1️⃣
final compose1 = const Compose(x2, 2).c1(x2);

Used to compose functions with only one input of type Input. If the function has more than one input, use Compose2, Compose3 (coming soon), etc.

Constructors

Compose(Output _compose(Input input), Input _input)
Instance of Compose given the function Output Function(Input input) to execute and the Input to pass to the function.

Methods

c1<ComposedOutput>(ComposedOutput c1Compose(Output output)) → Compose<Input, ComposedOutput>
Chain a function that takes the output Output from this Compose and returns a new Compose that when called will execute c1Compose, returning a value of type ComposedOutput.
c2<ComposedInput, ComposedOutput>(ComposedOutput c2Compose(Output output, ComposedInput composedInput), ComposedInput c2Input) → _ChainCompose12<Input, Output, ComposedInput, ComposedOutput>
Chain a function that takes two inputs:
call() → Output
Compute the result of the chain.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.

Operators

operator *(Compose<Input, Output> other(Output output)) → Compose<Input, Output>
Chain two Compose. The second Compose must have the same Input and Output of the first.
operator ==(Object other) → bool
The equality operator.
