Detailed Description

This file defines basic operations on an element in a refinement tree.

All operations work for all element classes by providing a virtual function table. For each element class, one implementation of the type and virtual table is required.

Typedef Documentation

◆ t8_element_t

typedef struct t8_element t8_element_t

Opaque structure for a generic element, only used as pointer.

Implementations are free to cast it to their internal data structure.

Function Documentation

◆ t8_scheme_cxx_ref()

void t8_scheme_cxx_ref ( t8_scheme_cxx_t * scheme )

Increase the reference counter of a scheme.

Parameters

[in,out] scheme On input, this scheme must be alive, that is, exist with positive reference count.

◆ t8_scheme_cxx_unref()

void t8_scheme_cxx_unref ( t8_scheme_cxx_t ** pscheme )

Decrease the reference counter of a scheme.

If the counter reaches zero, this scheme is destroyed.

Parameters

[in,out] pscheme On input, the scheme pointed to must exist with positive reference count. If the reference count reaches zero, the scheme is destroyed and this pointer set to NULL. Otherwise, the pointer is not changed and the scheme is not modified in other ways.
