Each CLASS variable is encapsulated by a class container, which is a
structure with two fields:
- * $data: A pointer to the actual data of the variable. This field has the
+ * _data: A pointer to the actual data of the variable. This field has the
declared type of the class variable and its attributes
(pointer/allocatable/dimension/...).
- * $vptr: A pointer to the vtable entry (see below) of the dynamic type.
+ * _vptr: A pointer to the vtable entry (see below) of the dynamic type.
For each derived type we set up a "vtable" entry, i.e. a structure with the
following fields:
- * $hash: A hash value serving as a unique identifier for this type.
- * $size: The size in bytes of the derived type.
- * $extends: A pointer to the vtable entry of the parent derived type.
- * $def_init: A pointer to a default initialized variable of this type.
- * $copy: A procedure pointer to a copying procedure.
+ * _hash: A hash value serving as a unique identifier for this type.
+ * _size: The size in bytes of the derived type.
+ * _extends: A pointer to the vtable entry of the parent derived type.
+ * _def_init: A pointer to a default initialized variable of this type.
+ * _copy: A procedure pointer to a copying procedure.
After these follow procedure pointer components for the specific
type-bound procedures. */
