public class: InputStreamEditor [javadoc | source]

java.lang.Object
   java.beans.PropertyEditorSupport
      org.springframework.beans.propertyeditors.InputStreamEditor

All Implemented Interfaces:
PropertyEditor

One-way PropertyEditor, which can convert from a text string to a java.io.InputStream, allowing InputStream properties to be set directly as a text string.

Supports Spring-style URL notation: any fully qualified standard URL ("file:", "http:", etc) and Spring's special "classpath:" pseudo-URL.

Note that in the default usage, the stream is not closed by Spring itself!
