java - I look for an explanation of libgdx's asset manager -

i create asset-manager. know asset-manager "libgdx" don't wanna use libgdx because programming studying purposes. wanna understand entire program , write scratch.

now need asset-manager because ran out of memory. took @ asset-manager of libgdx pretty code , don't understood completly.

i know basic principle/idea of libgdx's asset-manager. know works hashmaps , in own thread asyncron. pretty know.

could me?

there isn't more know, other it's using maps store , retrieve assets.

basically have this:

class assetmanager {      private map<string, object> assets = new hashmap<string, object>();      public void storeasset(string key, object asset) {         assets.put(key, asset);     }      public <t> t getasset(string key, class<t> clazz) {         return (t) assets.get(key);     }      public void freeasset(string key) {         assets.remove(key);     } } 

that generic getter optional, casts yourself, it's more convenient. of course there error handling , missing, that's how very basic assetmanager might work.
