Interface ToBooleanFunction1<T1>

Type Parameters:

T1 - the type of the input to the function

All Superinterfaces:

Arity, FunctionN<java.lang.Boolean>, InputChainable<T1>, InputChainableInput<T1>, ResultChainable<java.lang.Boolean>, ResultChainableResult<java.lang.Boolean>, ToBooleanFunctionN, UnboxedResult<Function1<T1,java.lang.Boolean>>

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface ToBooleanFunction1<T1>
extends ToBooleanFunctionN, InputChainableInput<T1>, UnboxedResult<Function1<T1,java.lang.Boolean>>

Represents a function that accepts one argument and produces a boolean-valued result. This is the one-arity specialization of ToBooleanFunctionN. This is the boolean-producing primitive specialization of Function1.

This is a functional interface whose functional method is applyAsBoolean(Object).

Since:

3.0.0

Method Detail

applyAsBoolean

boolean applyAsBoolean(T1 t1)

Applies this function to the given argument.

Parameters:

t1 - the function argument

Returns:

the function result

applyAllAsBooleanUnchecked

default boolean applyAllAsBooleanUnchecked(java.lang.Object... args)

Description copied from interface: ToBooleanFunctionN

Applies this function to the given arguments. Makes no assumptions of the arguments passed in and whether a value will compute successfully.

Specified by:

applyAllAsBooleanUnchecked in interface ToBooleanFunctionN

Parameters:

args - the function arguments

Returns:

the function result

arity

default int arity()

Description copied from interface: FunctionN

Returns the number of arguments of the function. If used as a functional interface with a non-specific number of arguments, this will return -1.

Specified by:

arity in interface Arity

Specified by:

arity in interface FunctionN<java.lang.Boolean>

Returns:

the number of arguments of the function

boxResult

default Function1<T1,java.lang.Boolean> boxResult()

Description copied from interface: UnboxedResult

Returns the boxed version of this object with a boxed result.

Specified by:

boxResult in interface UnboxedResult<Function1<T1,java.lang.Boolean>>

Returns:

the boxed version of this object with a boxed result

Function1

compose

default <V> ToBooleanFunction1<V> compose(Function1<? super V,? extends T1> before)

Description copied from interface: InputChainable

Returns a chained object that applies the before function to its input, and then applies this chainable object to the result. If evaluation of either throws an exception, it is relayed to the caller of the chained object.

Specified by:

compose in interface InputChainable<T1>

Specified by:

compose in interface InputChainableInput<T1>

Type Parameters:

V - the type of the input to the before function, and to then chained object

Parameters:

before - the function to apply before this chainable object is applied

Returns:

a chained object that first applies the before function and then applies this chainable object

composeUnchecked

default <V> ToBooleanFunction1<V> composeUnchecked(Function1<? super V,? extends T1> before)

Description copied from interface: InputChainable

Returns a chained object that applies the before function to its input, and then applies this chainable object to the result. If evaluation of either throws an exception, it is relayed to the caller of the chained object. This makes no assumptions on the arguments of this method.

Specified by:

composeUnchecked in interface InputChainable<T1>

Specified by:

composeUnchecked in interface InputChainableInput<T1>

Type Parameters:

V - the type of the input to the before function, and to then chained object

Parameters:

before - the function to apply before this chainable object is applied

Returns:

a chained object that first applies the before function and then applies this chainable object

andThen

default <V> Function1<T1,V> andThen(Function1<? super java.lang.Boolean,? extends V> after)

Description copied from interface: ResultChainable

Returns a chained object that applies this chainable object, and then applies the after function to ths result. If evaluation of either throws an exception, it is relayed to the caller of the chained object.

Specified by:

andThen in interface FunctionN<java.lang.Boolean>

Specified by:

andThen in interface ResultChainable<java.lang.Boolean>

Specified by:

andThen in interface ResultChainableResult<java.lang.Boolean>

Type Parameters:

V - the type of the output of the after function, and of the chained object

Parameters:

after - the function to apply after this chainable object is applied

Returns:

a chained object that applies this chainable object and then applies the after function

Function1

andThenUnchecked

default <V> Function1<T1,V> andThenUnchecked(Function1<? super java.lang.Boolean,? extends V> after)

Description copied from interface: ResultChainable

Returns a chained object that applies this chainable object, and then applies the after function to ths result. If evaluation of either throws an exception, it is relayed to the caller of the chained object. This makes no assumptions on the arguments of this method.

Specified by:

andThenUnchecked in interface FunctionN<java.lang.Boolean>

Specified by:

andThenUnchecked in interface ResultChainable<java.lang.Boolean>

Specified by:

andThenUnchecked in interface ResultChainableResult<java.lang.Boolean>

Type Parameters:

V - the type of the output of the after function, and of the chained object

Parameters:

after - the function to apply after this chainable object is applied

Returns:

a chained object that applies this chainable object and then applies the after function
