Module org.postgresql.pljava.internal

Package org.postgresql.pljava.internal

Interface Checked.FloatSupplier<E extends Throwable>

Type Parameters:

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

All Superinterfaces:

Checked<Checked.FloatSupplier<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.FloatSupplier<E extends Throwable>

A supplier of float-valued results, with a body that can throw checked exceptions.

Method Details

getAsFloat

float getAsFloat()
          throws E

Get the supplied value.

Throws:

E

use

static <E extends Throwable>
Checked.FloatSupplier<E> use(Checked.FloatSupplier<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.

ederWrap

default Checked.FloatSupplier<E> ederWrap()

Description copied from interface: Checked

Wraps this Checked functional interfaces as its corresponding Java functional interface WT, which possibly does not allow checked exceptions.

Checked exceptions of type EX may still, in reality, be thrown. This method is not intended to be called directly; it is used transparently by in(...), which passes the wrapper type into code that requires it, but re-exposes the original checked exception type to the compiler.

Specified by:

ederWrap in interface Checked<WT extends org.postgresql.pljava.internal.Checked.Closing.Trivial<WT,EX>,EX extends Throwable>
