class: ewol::Resource
Description:
A Resource is a generic interface to have an instance that have things that can be used by many people, ad have some hardware dependency.
For example of resources :
Shaders: openGL display interface.
Texture: openGL imega interface.
Font: Single file interface to store many glyphe ==> reduce the number of parallele loaded files.
ConfigFile: simple widget configuration files

Detail:
Resource
# Resource ();
generic protected contructor (use factory to create this class)
init
# void init ();
# void init (const std::string & _name);
Initialisation of the class and previous classes.
| Parameter [input]: | _name | Name of the resource. |
~Resource
+ virtual ~Resource ();
geenric destructor
m_resourceLevel
# uint8_t m_resourceLevel;
Level of the resource ==> for update priority [0..5] 0 must be update first.
getResourceLevel
+ uint8_t getResourceLevel ();
Get the current resource level;
updateContext
+ virtual void updateContext ();
Call when need to send data on the harware (openGL)
Note: This is done asynchronously with the create of the Resource.
removeContext
+ virtual void removeContext ();
The current OpenGl context is removing ==> remove yout own system data
removeContextToLate
+ virtual void removeContextToLate ();
The notification of the Context removing is too late, we have no more acces on the OpenGl context (thank you Android).
Juste update your internal state
reload
+ virtual void reload ();
User request the reload of all resources (usefull when the file depend on DATA:GUI:xxx ...
getManager
# ewol::resource::Manager & getManager ();
Get the current resource Manager
