Module org.postgresql.pljava.internal

Package org.postgresql.pljava.internal

Interface Checked.ToFloatFunction<T,E extends Throwable>

Type Parameters:

T - Type of the function's parameter.

E - Exception type that can be thrown by the body.

All Superinterfaces:

Checked<Checked.ToFloatFunction<T,E>,E>

Enclosing interface:

Checked<WT,EX extends Throwable>

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 static interface Checked.ToFloatFunction<T,E extends Throwable>

Represents a function that produces a float-valued result and can throw checked exceptions.

Method Detail

apply

float apply(T t)
     throws E extends Throwable

Applies this function to the given argument.

Throws:

E extends Throwable

use

static <T,E extends Throwable> Checked.ToFloatFunction<T,E> use(Checked.ToFloatFunction<T,E> o)

Shapes a lambda or method reference into an instance of this functional interface.

This is simply an identity function that can take the place of a more unwieldy cast.

Type Parameters:

E - Least upper bound of exception types o can throw.

Parameters:

o - The implementing lambda or method reference.
