# Package org.springframework.core.io

Generic abstraction for (file-based) resources, used throughout the framework.

Interface Summary
Interface | Description
--- | ---
ContextResource | Extended interface for a resource that is loaded from an enclosing 'context', e.g.
InputStreamSource | Simple interface for objects that are sources for an `InputStream`.
Resource | Interface for a resource descriptor that abstracts from the actual type of underlying resource, such as a file or class path resource.
ResourceLoader | Strategy interface for loading resources (e..
WritableResource | Extended interface for a resource that supports writing to it.

Class Summary
Class | Description
--- | ---
AbstractFileResolvingResource | Abstract base class for resources which resolve URLs into File references, such as `UrlResource` or `ClassPathResource`.
AbstractResource | Convenience base class for `Resource` implementations, pre-implementing typical behavior.
ByteArrayResource | `Resource` implementation for a given byte array.
ClassPathResource | `Resource` implementation for class path resources.
ClassRelativeResourceLoader | `ResourceLoader` implementation that interprets plain resource paths as relative to a given `java.lang.Class`.
DefaultResourceLoader | Default implementation of the `ResourceLoader` interface.
DescriptiveResource | Simple `Resource` implementation that holds a resource description but does not point to an actually readable resource.
FileSystemResource | `Resource` implementation for `java.io.File` handles.
FileSystemResourceLoader | `ResourceLoader` implementation that resolves plain paths as file system resources rather than as class path resources (the latter is `DefaultResourceLoader`'s default strategy).
InputStreamResource | `Resource` implementation for a given InputStream.
ResourceEditor | `Editor` for `Resource` descriptors, to automatically convert `String` locations e.g.
UrlResource | `Resource` implementation for `java.net.URL` locators.
VfsResource | VFS based `Resource` implementation.
VfsUtils | Utility for detecting the JBoss VFS version available in the classpath.
