Function Documentation

anchor() [1/2]

template<typename R >

static R & Inkscape::GC::anchor ( R &  r )

static

Increments the reference count of a anchored object.

This function template generates functions which take a reference to a anchored object of a given type, increment that object's reference count, and return a reference to the object of the same type as the function's parameter.

Parameters

m	a reference to a anchored object

Returns

the reference to the object

anchor() [2/2]

template<typename R >

static R * Inkscape::GC::anchor ( R *  r )

static

Increments the reference count of a anchored object.

This function template generates functions which take a pointer to a anchored object of a given type, increment that object's reference count, and return a pointer to the object of the same type as the function's parameter.

Parameters

m	a pointer to anchored object

Returns

the pointer to the object

release() [1/2]

template<typename R >

static R & Inkscape::GC::release ( R &  r )

static

Decrements the reference count of a anchored object.

This function template generates functions which take a reference to a anchored object of a given type, decrement that object's reference count, and return a reference to the object of the same type as the function's parameter.

The return value is safe to use since the object, even if its refcount has reached zero, will not actually be collected until there are no references to it in local variables or parameters.

Parameters

m	a reference to a anchored object

Returns

the reference to the object

release() [2/2]

template<typename R >

static R * Inkscape::GC::release ( R *  r )

static

Decrements the reference count of a anchored object.

This function template generates functions which take a pointer to a anchored object of a given type, decrement that object's reference count, and return a pointer to the object of the same type as the function's parameter.

The return value is safe to use since the object, even if its refcount has reached zero, will not actually be collected until there are no references to it in local variables or parameters.

Parameters

m	a pointer to a anchored object

Returns

the pointer to the object
