static void setDelegate ( FileUtils delegate)
static

You can inherit from platform dependent implementation of FileUtils, such as FileUtilsAndroid, and use this function to set delegate, then FileUtils will invoke delegate's implementation.

For example, your resources are encrypted, so you need to decrypt it after reading data from resources, then you can implement all getXXX functions, and engine will invoke your own getXX functions when reading data of resources.

If you don't want to system default implementation after setting delegate, you can just pass nullptr to this function.

It will delete previous delegate

virtual std::string
fullPathForFilename
( const std::string &  filename) const
virtual

Returns the fullpath for a given filename.

First it will try to get a new filename from the "filenameLookup" dictionary. If a new filename can't be found on the dictionary, it will use the original filename. Then it will try to obtain the full path of the filename using the FileUtils search rules: resolutions, and search paths. The file search is based on the array element order of search paths and resolution directories.

For instance:

We set two elements("/mnt/sdcard/", "internal_dir/") to search paths vector by setSearchPaths,
and set three elements("resources-ipadhd/", "resources-ipad/", "resources-iphonehd")
to resolutions vector by setSearchResolutionsOrder. The "internal_dir" is relative to "Resources/".

If we have a file named 'sprite.png', the mapping in fileLookup dictionary contains key: sprite.png -> value: sprite.pvr.gz. Firstly, it will replace 'sprite.png' with 'sprite.pvr.gz', then searching the file sprite.pvr.gz as follows:

/mnt/sdcard/resources-ipadhd/sprite.pvr.gz      (if not found, search next)
/mnt/sdcard/resources-ipad/sprite.pvr.gz        (if not found, search next)
/mnt/sdcard/resources-iphonehd/sprite.pvr.gz    (if not found, search next)
/mnt/sdcard/sprite.pvr.gz                       (if not found, search next)
internal_dir/resources-ipadhd/sprite.pvr.gz     (if not found, search next)
internal_dir/resources-ipad/sprite.pvr.gz       (if not found, search next)
internal_dir/resources-iphonehd/sprite.pvr.gz   (if not found, search next)
internal_dir/sprite.pvr.gz                      (if not found, return "sprite.png")

If the filename contains relative path like "gamescene/uilayer/sprite.png", and the mapping in fileLookup dictionary contains key: gamescene/uilayer/sprite.png -> value: gamescene/uilayer/sprite.pvr.gz. The file search order will be:

 /mnt/sdcard/gamescene/uilayer/resources-ipadhd/sprite.pvr.gz      (if not found, search next)
 /mnt/sdcard/gamescene/uilayer/resources-ipad/sprite.pvr.gz        (if not found, search next)
 /mnt/sdcard/gamescene/uilayer/resources-iphonehd/sprite.pvr.gz    (if not found, search next)
 /mnt/sdcard/gamescene/uilayer/sprite.pvr.gz                       (if not found, search next)
 internal_dir/gamescene/uilayer/resources-ipadhd/sprite.pvr.gz     (if not found, search next)
 internal_dir/gamescene/uilayer/resources-ipad/sprite.pvr.gz       (if not found, search next)
 internal_dir/gamescene/uilayer/resources-iphonehd/sprite.pvr.gz   (if not found, search next)
 internal_dir/gamescene/uilayer/sprite.pvr.gz                      (if not found, return "gamescene/uilayer/sprite.png")

If the new file can't be found on the file system, it will return the parameter filename directly.

This method was added to simplify multiplatform support. Whether you are using cocos2d-js or any cross-compilation toolchain like StellaSDK or Apportable, you might need to load different resources for a given file in the different platforms.

var fullPathForFilename ( var  filename)
virtual

Returns the fullpath for a given filename.

First it will try to get a new filename from the "filenameLookup" dictionary. If a new filename can't be found on the dictionary, it will use the original filename.

/mnt/sdcard/resources-iphonehd/sprite.pvr.gz    (if not found, search next)

internal_dir/resources-ipadhd/sprite.pvr.gz     (if not found, search next)
internal_dir/resources-ipad/sprite.pvr.gz       (if not found, search next)
internal_dir/resources-iphonehd/sprite.pvr.gz   (if not found, search next)
internal_dir/sprite.pvr.gz                      (if not found, return "sprite.png")

If the filename contains relative path like "gamescene/uilayer/sprite.png", and the mapping in fileLookup dictionary contains key: gamescene/uilayer/sprite.png -> value: gamescene/uilayer/sprite.pvr.gz. The file search order will be:

 /mnt/sdcard/gamescene/uilayer/resources-ipadhd/sprite.pvr.gz      (if not found, search next)

virtual void

virtual void setSearchPaths ( const std::vector< std::string > &  searchPaths)
virtual

Sets the array of search paths.

You can use this array to modify the search path of the resources. If you want to use "themes" or search resources in the "cache", you can do it easily by adding new entries in this array.

This method could access relative path and absolute path. If the relative path was passed to the vector, FileUtils will add the default resource directory before the relative path. For instance: On Android, the default resource root path is "assets/". If "/mnt/sdcard/" and "resources-large" were set to the search paths vector, "resources-large" will be converted to "assets/resources-large" since it was a relative path.

The array contains search paths.
