What is it?

A library of functional interfaces for Java 8 (now 11), concentrated on ability to handle checked exceptions (throwing lambda) and/or primitive types, supplemented with assertion classes, builders and some additional classes.

Features

• More of functional interfaces
  • More primitive types supported
  • More combinations of arguments.
  • List of interfaces:
    • action
    • suppliers
    • consumers
    • predicates
    • operators
    • ordinary functions
    • all interfaces
  • Support for throwing lambda expressions.
  • Support for exception handling
  • Default and static functions
    • including simple validations (throwIf)
  • With AssertJ assertions
  • With builders
• Thus, reducing number of cases where:
  • You cannot directly reference method
  • JVM cannot optimize code better (although nothing is guaranteed)
• Tuples
  • For each function that has a domain there exists in addition to that function a tuple class (e.g. Pair, Triple).
• Java 'monads'
  • Opt(ionals)
  • Fluent validations/checks

Most of the above goals adds to the actual number of interfaces so this is not very tinny library as one would think.
