Detailed Description

Base class for all OpenGL resources that reside in GPU memory.

Constructor & Destructor Documentation

Luminous::ResourceHandleGL::ResourceHandleGL ( StateGL &  state )

inline

Constructor.

Parameters

state

OpenGL state of the graphics driver

Luminous::ResourceHandleGL::ResourceHandleGL ( ResourceHandleGL &&  r )

inline

Move constructor.

Parameters

r	resource handle to move

Member Function Documentation

bool Luminous::ResourceHandleGL::expired ( ) const

inline

Check if the resource has expired.

Resource is considered expired if the time since it was last accessed exceeds the defined expiration time. Expired resources are released by the graphics driver to conserve GPU memory.

touch

GLuint Luminous::ResourceHandleGL::handle ( ) const

inline

Get the raw OpenGL handle for the resource.

Returns

raw OpenGL handle

ResourceHandleGL & Luminous::ResourceHandleGL::operator= ( ResourceHandleGL &&  r )

inline

Move assignment operator.

Parameters

r	resource handle to move

void Luminous::ResourceHandleGL::setExpirationSeconds ( unsigned int  secs )

inline

Set the expiration time in seconds for the resource.

Parameters

secs	expiration time in seconds

touch

expired

void Luminous::ResourceHandleGL::touch ( )

inline
