All interfaces are part of the zenscriptx.fun package, meaning that the fully qualified name for a class X is zenscriptx.fun.X, which is useful for importing.

In the following list, functions are split into categories that represent what their general use is. Also, in all of the functions definitions, the letters T, U, and R define generic types, i.e. types that can be specified by the developer.

A BiConsumer accepts two elements, which can be of different types, and consumes them, meaning uses them for internal processing and returns nothing.

Class Name	Function Signature	Notes
Class Name BiConsumer	Function Signature function accept(t as T, u as U) as void;	Notes -
Class Name ObjDoubleConsumer	Function Signature function accept(t as T, value as double) as void;	Notes -
Class Name ObjIntConsumer	Function Signature function accept(t as T, value as int) as void;	Notes -
Class Name ObjLongConsumer	Function Signature function accept(t as T, value as long) as void;	Notes -

A BiFunction applies a function to two elements, which can be of different types, returning a single element, which can also be of a different type. It can be pictured mathematically as r = f(s, t), where f is the bifunction.

Class Name	Function Signature	Notes
Class Name BiFunction	Function Signature function apply(t as T, u as U) as R;	Notes -
Class Name ToDoubleBiFunction	Function Signature function apply(t as T, u as U) as double;	Notes -
Class Name ToIntBiFunction	Function Signature function apply(t as T, u as U) as int;	Notes -
Class Name ToLongBiFunction	Function Signature function apply(t as T, u as U) as long;	Notes -

A Binary Operator applies a function to two elements of the same type, returning another element, which has the same type as the inputs. It can be mathematically pictured as r = s op t, where op is the binary operator.

Class Name	Function Signature	Notes
Class Name BinaryOperator	Function Signature function apply(t as T, u as T) as T;	Notes BinaryOperator extends BiFunction
Class Name DoubleBinaryOperator	Function Signature function applyAsDouble(left as double, right as double) as double;	Notes -
Class Name IntBinaryOperator	Function Signature function applyAsInt(left as int, right as int) as int;	Notes -
Class Name LongBinaryOperator	Function Signature function applyAsLong(left as long, right as long) as long;	Notes -

A BiPredicate tests the two given inputs, which may be of different types, and returns a boolean, representing whether they passed the test or not.

Class Name	Function Signature	Notes
Class Name BiPredicate	Function Signature function test(t as T, u as U) as bool;	Notes -

A Consumer accepts a single element and consumes it, meaning it uses it for internal processing and returns nothing.

Class Name	Function Signature	Notes
Class Name Consumer	Function Signature function accept(t as T) as void;	Notes -
Class Name DoubleConsumer	Function Signature function accept(value as double) as void;	Notes -
Class Name IntConsumer	Function Signature function accept(value as int) as void;	Notes -
Class Name LongConsumer	Function Signature function accept(value as long) as void;	Notes -

A Function applies a function to a single element, returning another element, which can be a different type from the inputs. It can be pictured mathematically as r = f(t), where f is the function.

Class Name LongFunction	Function Signature function apply(value as long) as R;	Notes -
Class Name LongToDoubleFunction	Function Signature function applyAsDouble(value as long) as double;	Notes -
Class Name LongToIntFunction	Function Signature function applyAsInt(value as long) as int;	Notes -
Class Name ToDoubleFunction	Function Signature function apply(value as T) as double;	Notes -
Class Name ToIntFunction	Function Signature function apply(value as T) as int;	Notes -
Class Name ToLongFunction	Function Signature function apply(value as T) as long;	Notes -

A Predicate tests the given input and returns a boolean, representing whether it passed the test or not.

Class Name	Function Signature	Notes
Class Name Predicate	Function Signature function test(t as T) as bool;	Notes -
Class Name DoublePredicate	Function Signature function test(value as double) as bool;	Notes -
Class Name IntPredicate	Function Signature function test(value as int) as bool;	Notes -
Class Name LongPredicate	Function Signature function test(value as long) as bool;	Notes -

A Supplier outputs an instance of a given type, be it either created on the fly or cached.

Class Name	Function Signature	Notes
Class Name Supplier	Function Signature function get() as T;	Notes -
Class Name BooleanSupplier	Function Signature function getAsBoolean() as bool;	Notes -
Class Name DoubleSupplier	Function Signature function getAsDouble() as double;	Notes -
Class Name IntSupplier	Function Signature function getAsInt() as int;	Notes -
Class Name LongSupplier	Function Signature function getAsLong() as long;	Notes -

A Unary operator applies a function to an element of a given type, returning another element, which has to be of the same type as the inputs. It can be pictured mathematically as r = op t, where op is the unary operator.

Class Name	Function Signature	Notes
Class Name UnaryOperator	Function Signature function apply(t as T) as T;	Notes UnaryOperator extends Function
Class Name DoubleUnaryOperator	Function Signature function applyAsDouble(operand as double) as double;	Notes -
Class Name IntUnaryOperator	Function Signature function applyAsInt(operand as int) as int;	Notes -
