Pointer is a standard auto_ptr-like smart pointer for managing heap allocated reference counted objects. T must be a class derived from scim::ReferencedObject.

Construct a new smart pointer.
Initialize a new Pointer with any dumb pointer. Definition at line 80 of file scim_pointer.h. |
|
Copy constructor.
Initialize a new Pointer with any compatible Pointer. Definition at line 89 of file scim_pointer.h. |
|
Copy constructor.
Initialize a new Pointer of type T from a Pointer of type T1, only if T1 is derived from T. Definition at line 99 of file scim_pointer.h. |
|
Destructor. Decreases the object reference count. Definition at line 109 of file scim_pointer.h. |
|
Assignment operator.
Releases the current dumb pointer, if any and assigns object to this Pointer, incrementing its reference count. Definition at line 116 of file scim_pointer.h. |
|
Assignment operator.
Releases the current dumb pointer, if any and assigns the dumb pointer managed by src to this Pointer, incrementing its reference count. Definition at line 127 of file scim_pointer.h. |
|
Assignment operator.
Releases the current dumb pointer, if any and assigns the dumb pointer of type T1 managed by src to this Pointer as a dumb pointer of type T, only if T1 is derived from T. The reference count is incremented. Definition at line 139 of file scim_pointer.h. |
|
Dereference operator.
Definition at line 155 of file scim_pointer.h. |
|
Member selection operator.
Definition at line 162 of file scim_pointer.h. |
|
Conversion operator. Converts a Pointer into its dumb pointer: the C pointer it manages. Normally it is considered pretty evil to mix smart and regular pointers. In scim you can safely if you just follow the reference counting rules for each of them. You can never call delete on Pointer either because you don't call delete on scim objects; you call unref(). Definition at line 169 of file scim_pointer.h. |
|
Returns the dumb pointer; the regular C pointer managed by the Pointer.
Definition at line 180 of file scim_pointer.h. Referenced by scim::Pointer< Slot >::operator *(), scim::Pointer< Slot >::operator T *(), scim::Pointer< Slot >::operator->(), and scim::Node::slot(). |
|
Returns true if the Pointer has no dumb pointer.
Definition at line 187 of file scim_pointer.h. |
|
Releases the dumb pointer.
Before releasing the dumb pointer its reference count is incremented to prevent it being destroyed. You must call unref() on the pointer to prevent a memory leak. Definition at line 197 of file scim_pointer.h. |
|
Sets a new dumb pointer for the Pointer to manage.
Releases the current dumb pointer, if any, and assigns object to the Pointer, incrementing its reference count. Definition at line 212 of file scim_pointer.h. |
|
Compares two Pointers.
