com.dua3.utility.lang.LangUtil.AutoClosableCachingSupplier<T>

Type Parameters:

T - the type of the object supplied, which may be nullable

All Implemented Interfaces:

LangUtil.AutoCloseableSupplier<T>, LangUtil.CachingSupplier<T>, AutoCloseable, Supplier<T>

Enclosing class:

LangUtil

public static final class LangUtil.AutoClosableCachingSupplier<T extends @Nullable Object>
extends LangUtil.StrongCachingSupplier<T>
implements LangUtil.AutoCloseableSupplier<T>

A supplier implementation that extends CachingSupplier and implements the AutoCloseableSupplier interface. This class provides the capability to cache the result of a computation and automatically clean up resources when the cache is reset or the instance is closed.

When the cached value is invalidated, either through reset() or close(), a provided Consumer is invoked to clean up any associated resources.

Method Details

get

public T get()

Specified by:

get in interface Supplier<T extends @Nullable Object>

Overrides:

get in class LangUtil.StrongCachingSupplier<T extends @Nullable Object>

reset

public void reset()

Description copied from class: LangUtil.StrongCachingSupplier

Resets the internal state of this supplier by clearing the cached object and marking it as uninitialized. After calling this method, the next invocation of LangUtil.StrongCachingSupplier.get() will recompute and cache the value by invoking the underlying supplier.

The method has no effect if the supplier is already in the uninitialized state.

Specified by:

reset in interface LangUtil.CachingSupplier<T extends @Nullable Object>

Overrides:

reset in class LangUtil.StrongCachingSupplier<T extends @Nullable Object>

close

public void close()

Specified by:

close in interface AutoCloseable

Specified by:

close in interface LangUtil.AutoCloseableSupplier<T extends @Nullable Object>
