Public Types | |
typedef ACE_Hash_Map_With_Allocator< TAO_Persistent_ExtId, TAO_Persistent_IntId > | HASH_MAP |
Underlying data structure - typedef for ease of use. More... | |
Public Methods | |
TAO_Persistent_Bindings_Map (CORBA::ORB_ptr orb) | |
Constructor. More... | |
int | open (size_t hash_map_size, ACE_Allocator *alloc) |
Allocate hash map of size <hash_map_size> from persistent storage using the <alloc>. More... | |
void | set (HASH_MAP *map, ACE_Allocator *alloc) |
The hash map has already been preallocated for us. We just need to set our data members take ownership of it. More... | |
virtual | ~TAO_Persistent_Bindings_Map (void) |
Destructor. Does not deallocate the hash map: if an instance of this class goes out of scope, its hash_map remains in persistent storage. More... | |
void | destroy (void) |
This method removes the hash map from persistent storage/frees up the memory. More... | |
HASH_MAP * | map (void) |
Get a pointer to the underlying hash map. More... | |
size_t | total_size (void) |
Return the size of the underlying hash table. More... | |
virtual size_t | current_size (void) |
Return the size of the underlying hash table. More... | |
virtual int | bind (const char *id, const char *kind, CORBA::Object_ptr obj, CosNaming::BindingType type) |
Add a binding with the specified parameters to the table. More... | |
virtual int | rebind (const char *id, const char *kind, CORBA::Object_ptr obj, CosNaming::BindingType type) |
Overwrite a binding containing <id> and <kind> (or create a new one if one doesn't exist) with the specified parameters. More... | |
virtual int | unbind (const char *id, const char *kind) |
Remove a binding containing <id> and <kind> from the table. More... | |
virtual int | find (const char *id, const char *kind, CORBA::Object_ptr &obj, CosNaming::BindingType &type) |
Find the binding containing <id> and <kind> in the table, and pass binding's type and object back to the caller by reference. More... | |
Protected Methods | |
int | open_helper (size_t hash_table_size, void *buffer) |
Helper to the <open> method. More... | |
int | shared_bind (const char *id, const char *kind, CORBA::Object_ptr obj, CosNaming::BindingType type, int rebind) |
Helper: factors common code from <bind> and <rebind>. More... | |
Protected Attributes | |
ACE_Allocator * | allocator_ |
Pointer to the allocator we use to make bindings persistent. More... | |
HASH_MAP * | map_ |
Pointer to the underlying hash map. More... | |
CORBA::ORB_var | orb_ |
Pointer to the orb. We need it to do string/object conversions. More... |
Wrapper on top of ACE_Hash_Map_With_Allocator (which is a wrapper around ACE_Hash_Map_Manager). Uses ACE_Allocator (allocating from persistent storage) to make bindings persistent and supports TAO_Bindings_Map interface. Used by TAO_Persistent_Naming_Context.
|
Underlying data structure - typedef for ease of use.
|
|
Constructor.
|
|
Destructor. Does not deallocate the hash map: if an instance of this class goes out of scope, its hash_map remains in persistent storage.
|
|
Add a binding with the specified parameters to the table. Return 0 on success and -1 on failure, 1 if there already is a binding with <id> and <kind>. Reimplemented from TAO_Bindings_Map. |
|
Return the size of the underlying hash table.
Reimplemented from TAO_Bindings_Map. |
|
This method removes the hash map from persistent storage/frees up the memory. The hash map better be empty, since we are not cleaning up the insides. (We could add <close> to clean entries, but not the data inside the entries. |
|
Find the binding containing <id> and <kind> in the table, and pass binding's type and object back to the caller by reference. Return 0 on success and -1 on failure. Note: a 'duplicated' object reference is assigned to <obj>, so the caller is responsible for its deallocation. Reimplemented from TAO_Bindings_Map. |
|
Get a pointer to the underlying hash map.
|
|
Allocate hash map of size <hash_map_size> from persistent storage using the <alloc>.
|
|
Helper to the <open> method. By isolating placement new into a separate method, we can deal with memory allocation failures more efficiently. If there is a problem in HASH_MAP constructor, we can clean up preallocated space. |
|
Overwrite a binding containing <id> and <kind> (or create a new one if one doesn't exist) with the specified parameters. Return 0 or 1 on success. Return -1 or -2 on failure. (-2 is returned if the new and old bindings differ in type). Reimplemented from TAO_Bindings_Map. |
|
The hash map has already been preallocated for us. We just need to set our data members take ownership of it.
|
|
Helper: factors common code from <bind> and <rebind>.
|
|
Return the size of the underlying hash table.
|
|
Remove a binding containing <id> and <kind> from the table. Return 0 on success and -1 on failure. Reimplemented from TAO_Bindings_Map. |
|
Pointer to the allocator we use to make bindings persistent.
|
|
Pointer to the underlying hash map.
|
|
Pointer to the orb. We need it to do string/object conversions.
