groovy - Grails Project DTOs in Java -


in grails there plug-in compile ":dto:0.2.4" transfer domain objects dtos. when using plug-in dtos created java classes.

for example if there domain class person.groovy dto created persondto.java

what intention of kind of behavior ? comment appreciated.

peter ledbrook answer question in this blog post.

despite that, dtos still persist (pardon pun). when want serialise data on rpc, they’re 1 of few options available you. gwt-rpc case in point, , reason grails dto plugin. gilead allows transparently serialise hibernate domain instances, works if domain class can loaded client. since gorm domain classes typically groovy, that’s not option gwt. typical grails domain class includes bunch of stuff client hardly going interested in, custom mappings.

so, can lightweight version of domain class, data client needs.

not case of grails, have static methods database query's, if have dao class, dto pattern can used ensure client not allowed perform methods touch database. can ensure inappropriate use of objects in presentation layer.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
