Functions

static void	CBLCollection_Release (const CBLCollection *t)
Collection Accessors
Getting information about a collection.
CBLScope *	CBLCollection_Scope (const CBLCollection *collection)
	Returns the scope of the collection. More...
FLString	CBLCollection_Name (const CBLCollection *collection)
	Returns the collection name. More...
uint64_t	CBLCollection_Count (const CBLCollection *collection)
	Returns the number of documents in the collection. More...
Document lifecycle
_cbl_warn_unused const CBLDocument *_cbl_nullable	CBLCollection_GetDocument (const CBLCollection *collection, FLString docID, CBLError *_cbl_nullable outError)
	Reads a document from the collection, creating a new (immutable) CBLDocument object. More...
bool	CBLCollection_SaveDocument (CBLCollection *collection, CBLDocument *doc, CBLError *_cbl_nullable outError)
	Saves a (mutable) document to the collection. More...
bool	CBLCollection_SaveDocumentWithConcurrencyControl (CBLCollection *collection, CBLDocument *doc, CBLConcurrencyControl concurrency, CBLError *_cbl_nullable outError)
	Saves a (mutable) document to the collection. More...
bool	CBLCollection_SaveDocumentWithConflictHandler (CBLCollection *collection, CBLDocument *doc, CBLConflictHandler conflictHandler, void *_cbl_nullable context, CBLError *_cbl_nullable outError)
	Saves a (mutable) document to the collection, allowing for custom conflict handling in the event that the document has been updated since doc was loaded. More...
bool	CBLCollection_DeleteDocument (CBLCollection *collection, const CBLDocument *document, CBLError *_cbl_nullable outError)
	Deletes a document from the collection. More...
bool	CBLCollection_DeleteDocumentWithConcurrencyControl (CBLCollection *collection, const CBLDocument *document, CBLConcurrencyControl concurrency, CBLError *_cbl_nullable outError)
	Deletes a document from the collection. More...
bool	CBLCollection_PurgeDocument (CBLCollection *collection, const CBLDocument *document, CBLError *_cbl_nullable outError)
	Purges a document. More...
bool	CBLCollection_PurgeDocumentByID (CBLCollection *collection, FLString docID, CBLError *_cbl_nullable outError)
	Purges a document, given only its ID. More...
CBLTimestamp	CBLCollection_GetDocumentExpiration (CBLCollection *collection, FLSlice docID, CBLError *_cbl_nullable outError)
	Returns the time, if any, at which a given document will expire and be purged. More...
bool	CBLCollection_SetDocumentExpiration (CBLCollection *collection, FLSlice docID, CBLTimestamp expiration, CBLError *_cbl_nullable outError)
	Sets or clears the expiration time of a document. More...
Mutable documents
The type CBLDocument* without a const qualifier refers to a mutable document instance. A mutable document exposes its properties as a mutable dictionary, so you can change them in place and then call CBLCollection_SaveDocument to persist the changes.
_cbl_warn_unused CBLDocument *_cbl_nullable	CBLCollection_GetMutableDocument (CBLCollection *collection, FLString docID, CBLError *_cbl_nullable outError)
	Reads a document from the collection, in mutable form that can be updated and saved. More...
Query Indexes
bool	CBLCollection_CreateValueIndex (CBLCollection *collection, FLString name, CBLValueIndexConfiguration config, CBLError *_cbl_nullable outError)
	Creates a value index in the collection. More...
bool	CBLCollection_CreateFullTextIndex (CBLCollection *collection, FLString name, CBLFullTextIndexConfiguration config, CBLError *_cbl_nullable outError)
	Creates a full-text index in the collection. More...
bool	CBLCollection_DeleteIndex (CBLCollection *collection, FLString name, CBLError *_cbl_nullable outError)
	Deletes an index in the collection by name. More...
_cbl_warn_unused FLMutableArray _cbl_nullable	CBLCollection_GetIndexNames (CBLCollection *collection, CBLError *_cbl_nullable outError)
	Returns the names of the indexes in the collection, as a Fleece array of strings. More...

Change Listeners
A collection change listener lets you detect changes made to all documents in a collection. (If you want to observe specific documents, use a CBLCollectionDocumentChangeListener instead.) Note If there are multiple CBLCollection instances on the same database file, each one's listeners will be notified of changes made by other collection instances. Warning Changes made to the database file by other processes will not be notified.
typedef void(*	CBLCollectionChangeListener) (void *_cbl_nullable context, const CBLCollectionChange *change)
	A collection change listener callback, invoked after one or more documents are changed on disk. More...
_cbl_warn_unused CBLListenerToken *	CBLCollection_AddChangeListener (const CBLCollection *collection, CBLCollectionChangeListener listener, void *_cbl_nullable context)
	Registers a collection change listener callback. More...

Document listeners
A document change listener lets you detect changes made to a specific document after they are persisted to the collection. Note If there are multiple CBLCollection instances on the same database file, each one's document listeners will be notified of changes made by other collection instances.
typedef void(*	CBLCollectionDocumentChangeListener) (void *context, const CBLDocumentChange *change)
	A document change listener callback, invoked after a specific document is changed on disk. More...
_cbl_warn_unused CBLListenerToken *	CBLCollection_AddDocumentChangeListener (const CBLCollection *collection, FLString docID, CBLCollectionDocumentChangeListener listener, void *_cbl_nullable context)
	Registers a document change listener callback. More...
