# f

Provides some useful (especially for method references) functional methods for Java 8

## Example

```java

import static run.smt.f.functional.Pipes.*;

import static run.smt.f.functional.signaturemanip.ArgumentManipulation.*;

import static run.smt.f.functional.signaturemanip.ReturnManipulation.*;

import static run.smt.f.predef.LogicChecks.*;

import static run.smt.f.predef.LogicOperator.*;

class Example {

    public void usage() {

        getSomeStream()

            .filter(and(this::isUseful, this::isGood))

            .filter(not(this::isWrong))

            .filter(isNotNull())

            .map(pipe(bind(this::convertToPojo, getArg()), Pojo::getField))

            .foreach(expand(this::dontNeedArgs));

    }

    private Stream getSomeStream() {}

    private boolean isUseful(Object elem) {}

    private boolean isGood(Object elem) {}

    private boolean isWrong(Object elem) {}

    private Arg getArg() {}

    private Pojo convertToPojoWithArg(Arg arg, Object elem) {}

    private void dontNeedArgs() {}

}

```

## Modules

 - `definition` - Definition of functional interfaces

 - `functional` - Wrapper for easier usage with method references, contains all methods of functional interfaces as static methods

 - `predicate` - Definition of predicates, extended methods in functional interfaces for easier usage with functions returning boolean values

 - `predef` - Predefined operations and checks for both simple functional interfaces from `definition` and `predicate`

 - `all` - Parent module for all listed above
