org.springframework.core.io: public interface: InputStreamSource

org.springframework.core.io
public interface: InputStreamSource [javadoc | source]

All Known Implementing Classes:
FileSystemContextResource, InputStreamResource, ContextResource, FileSystemResource, UrlResource, DescriptiveResource, PortletContextResource, ClassPathResource, AbstractResource, BeanDefinitionResource, Resource, ByteArrayResource, ServletContextResource, ClassPathContextResource

Simple interface for objects that are sources for an InputStream .

This is the base interface for Spring's more extensive Resource interface.

For single-use streams, InputStreamResource can be used for any given InputStream. Spring's ByteArrayResource or any file-based Resource implementation can be used as a concrete instance, allowing one to read the underlying content stream multiple times. This makes this interface useful as an abstract content source for mail attachments, for example.

Method from org.springframework.core.io.InputStreamSource Summary:
getInputStream

Method from org.springframework.core.io.InputStreamSource Detail:
public InputStream getInputStream() throws IOException Return an InputStream . It is expected that each call creates a fresh stream. This requirement is particularly important when you consider an API such as JavaMail, which needs to be able to read the stream multiple times when creating mail attachments. For such a use case, it is required that each `getInputStream()` call returns a fresh stream.
