~GFXGLVertexBuffer ()

virtual void lock (U32 vertexStart, U32 vertexEnd, void **vertexPtr)

calls glMapBuffer and offsets the pointer by vertex start

calls glUnmapBuffer, unbinds the buffer

virtual void prepare ()

Binds the buffer.

virtual void finish ()

GLvoid * getBuffer ()

returns NULL

virtual void zombify ()

When called the resource should destroy all device sensitive information (e.g. D3D resources in D3DPOOL_DEFAULT.

virtual void resurrect ()

When called the resource should restore all device sensitive information destroyed by zombify().
