-Editor for java.io.InputStream, to directly feed an InputStream%0A * property instead of using a String location property.
+One-way PropertyEditor, which can convert from a text string to an%0A * InputStream, allowing InputStream properties to be set directly as%0A * a text string. The string should be suitable for feeding to a %0A * ResourceEditor, since this is what is actually used to produce a%0A * Resource from the text, which is then asked for an InputStream.%0A * Note that in the default usage the stream is not %0A * closed by Spring itself!
