inputStream

public InputStream inputStream()
                        throws ResourceException

Description copied from interface: FileResource

Opens a new input stream to read the contents of a resource and returns it. Note that implementations may be allocating native memory for the stream, so callers need to close this when they are done with it. users of this method should follow the pattern: close the stream where you open it.

Specified by:

inputStream in interface FileResource

Returns:

just opened InputStream

Throws:

ResourceException - is the file does not exists or if the resource is a directory
