Member Function Documentation

rGLuintObject::operator GLuint

(

)

implicit conversion to GLuints, auto-creating the object

Returns:

the GLUint representing the object, always guaranteed to be valid

Definition at line 38 of file rGLuintObject.cpp.

References Gen(), and object_.

{
    // auto-generate the object
    Gen();
    return object_;
}

Here is the call graph for this function:

bool rGLuintObject::IsValid

(

)

const

checks whether the object is valid

Returns:

true if the object is currently valid (meaning: Gen() has been called after Delete())

Definition at line 46 of file rGLuintObject.cpp.

References object_.

{
    return object_;
}

void rGLuintObject::Gen

(

)

reserve the object

Definition at line 55 of file rGLuintObject.cpp.

References DoGen(), object_, and sr_CheckGLError().

Referenced by operator GLuint().

{
    if ( !object_ )
    {
        sr_CheckGLError();
        DoGen();
        sr_CheckGLError();
    }
}

Here is the caller graph for this function:

void rGLuintObject::Delete

(

)

free the object

Definition at line 65 of file rGLuintObject.cpp.

References DoDelete(), object_, and sr_CheckGLError().

Referenced by rGluintObjectDummy::~rGluintObjectDummy().
