InputStreamResource

Class Overview

Resource implementation for a given InputStream. Should only be used if no specific Resource implementation is applicable. In particular, prefer ByteArrayResource or any of the file-based Resource implementations where possible.

In contrast to other Resource implementations, this is a descriptor for an already opened resource - therefore returning "true" from isOpen(). Do not use it if you need to keep the resource descriptor somewhere, or if you need to read a stream multiple times.

Summary

[Expand] Inherited Methods
From class org.springframework.core.io.AbstractResource long contentLength() This implementation checks the timestamp of the underlying File, if available. Resource createRelative(String relativePath) This implementation throws a FileNotFoundException, assuming that relative resources cannot be created for this resource. boolean equals(Object obj) This implementation compares description strings. boolean exists() This implementation checks whether a File can be opened, falling back to whether an InputStream can be opened. File getFile() This implementation throws a FileNotFoundException, assuming that the resource cannot be resolved to an absolute file path. File getFileForLastModifiedCheck() Determine the File to use for timestamp checking. String getFilename() This implementation always throws IllegalStateException, assuming that the resource does not have a filename. URI getURI() This implementation builds a URI based on the URL returned by getURL(). URL getURL() This implementation throws a FileNotFoundException, assuming that the resource cannot be resolved to a URL. int hashCode() This implementation returns the description's hash code. boolean isOpen() This implementation always returns false. boolean isReadable() This implementation always returns true. long lastModified() This implementation checks the timestamp of the underlying File, if available. String toString() This implementation returns the description of this resource.

From interface org.springframework.core.io.InputStreamSource abstract InputStream getInputStream() Return an InputStream.
From interface org.springframework.core.io.Resource abstract long contentLength() Determine the content length for this resource. abstract Resource createRelative(String relativePath) Create a resource relative to this resource. abstract boolean exists() Return whether this resource actually exists in physical form. abstract String getDescription() Return a description for this resource, to be used for error output when working with the resource. abstract File getFile() Return a File handle for this resource. abstract String getFilename() Return a filename for this resource, i.e. abstract URI getURI() Return a URI handle for this resource. abstract URL getURL() Return a URL handle for this resource. abstract boolean isOpen() Return whether this resource represents a handle with an open stream. abstract boolean isReadable() Return whether the contents of this resource can be read, e.g. abstract long lastModified() Determine the last-modified timestamp for this resource.
