org.htmlparser.lexer.Source.destroy()
Close the source. Once a source has been closed, further {@link #read() read}, {@link #ready ready}, {@link #mark mark}, {@link #reset reset}, {@link #skip skip}, {@link #unread unread}, {@link #getCharacter getCharacter} or {@link #getString getString}invocations will throw an IOException. Closing a previously-closed source, however, has no effect.
@exception IOException If an I/O error occurs.
