java - Getting a List of files from a class path entry -


i facing problem in application cannot list resource class path entry.

enumeration<url> resources = thread.currentthread().getcontextclassloader().getresources("src/main/resources/*.*"); system.out.println(resources); while (resources.hasmoreelements()) {   url url = resources.nextelement();   //here getting empty url list.please help.   system.out.println(url); }

the couple of problems:

  1. src/main/resources/*.* not valid syntax classloader.getresources()
    • the path must full path, e.g. src/main/resources
  2. why trying load classes src/main/resources directory?
    • it assumes resources in such directory, work development purposes
    • after compilation resources stored in different directory (maven put top level directory default) , program not work correctly

javascript - IIFE: var vs this - is there any difference? -

is there difference between this , var in invoced function expressions(iife)? (function(){ var foo = 0; this.bar = 0; })(); if code executed in global context, 2 options: you're in use strict mode, , in case this points nothing (null or undefined) , you'll see exception. you're not in use strict mode , this points window, in case you'll set bar global variable. var keeps variable local (same scope run in) , not exposed outside calls of iife.

r - Grow a ffdf data frame on disk gradually -

from documentation of save.ffdf: using ‘save.ffdf’ automagically sets ‘finalizer’s of ‘ff’ vectors ‘"close"’. means data preserved on disk when object removed or r sessions closed. data can deleted either using ‘delete’ or removing directory object saved (‘dir’). i want starting small ffdf data frame, add bit new data @ time, , grow on disk. did little experiment: # in r ffiris = as.ffdf(iris) save.ffdf(ffiris, dir = "~/desktop/iris") # in bash ls ~/desktop/iris/ ## ffiris$petal.length.ff ffiris$petal.width.ff ffiris$sepal.length.ff ffiris$sepal.width.ff ffiris$species.ff # in r # add new column ffiris =transform(ffiris, new1 = rep(99, nrow(iris))) rm(ffiris) # in bash ls ~/desktop/iris/ ## ffiris$petal.length.ff ffiris$petal.width.ff ffiris$sepal.length.ff ffiris$sepal.width.ff ffiris$species.ff it turns out doesn't automatically update ff data on disk when remove ffiris. saving manually? # in r # add new column ffiris =tran...
