Package dev.enola.common.io.resource

Class EmptyResource

java.lang.Object

dev.enola.common.io.resource.BaseResource

dev.enola.common.io.resource.EmptyResource

All Implemented Interfaces:

AbstractResource, ReadableButNotWritableResource, ReadableResource, Resource, WritableResource

public class EmptyResource
extends BaseResource
implements ReadableButNotWritableResource

Read-only resources which when read are always immediately EOF (like "data:,"). This is a bit like /dev/null on *NIX OS for reading, but not for writing (because /dev/null ignores writes, whereas this fails).

See Also:

• for an alternative that returns infinite 0s instead of EOF.
