FLDoc | |
An FLDoc points to (and often owns) Fleece-encoded data and provides access to its Fleece values. | |
NODISCARD FLEECE_PUBLIC FLDoc | FLDoc_FromResultData (FLSliceResult data, FLTrust, FLSharedKeys FL_NULLABLE, FLSlice externData) |
Creates an FLDoc from Fleece-encoded data that's been returned as a result from FLSlice_Copy or other API. More... | |
FLEECE_PUBLIC void | FLDoc_Release (FLDoc FL_NULLABLE) |
Releases a reference to an FLDoc. More... | |
FLEECE_PUBLIC FLDoc | FLDoc_Retain (FLDoc FL_NULLABLE) |
Adds a reference to an FLDoc. More... | |
FLEECE_PUBLIC FLSlice | FLDoc_GetData (FLDoc FL_NULLABLE) FLPURE |
Returns the encoded Fleece data backing the document. More... | |
FLEECE_PUBLIC FLSliceResult | FLDoc_GetAllocedData (FLDoc FL_NULLABLE) FLPURE |
Returns the FLSliceResult data owned by the document, if any, else a null slice. More... | |
FLEECE_PUBLIC FLValue | FLDoc_GetRoot (FLDoc FL_NULLABLE) FLPURE |
Returns the root value in the FLDoc, usually an FLDict. More... | |
FLEECE_PUBLIC FLSharedKeys | FLDoc_GetSharedKeys (FLDoc FL_NULLABLE) FLPURE |
Returns the FLSharedKeys used by this FLDoc, as specified when it was created. More... | |
NODISCARD FLEECE_PUBLIC FLDoc FL_NULLABLE | FLValue_FindDoc (FLValue FL_NULLABLE) FLPURE |
Looks up the Doc containing the Value, or NULL if there is none. More... | |
FLEECE_PUBLIC bool | FLDoc_SetAssociated (FLDoc FL_NULLABLE doc, void *FL_NULLABLE pointer, const char *type) |
Associates an arbitrary pointer value with a document, and thus its contained values. More... | |
FLEECE_PUBLIC void * | FLDoc_GetAssociated (FLDoc FL_NULLABLE doc, const char *type) FLPURE |
Returns the pointer associated with the document. More... | |
NODISCARD FLEECE_PUBLIC FLDoc FLDoc_FromResultData | ( | FLSliceResult | data, |
FLTrust | , | ||
FLSharedKeys | FL_NULLABLE, | ||
FLSlice | externData | ||
) |
Creates an FLDoc from Fleece-encoded data that's been returned as a result from FLSlice_Copy or other API.
The resulting document retains the data, so you don't need to worry about it remaining valid.
FLEECE_PUBLIC FLSliceResult FLDoc_GetAllocedData | ( | FLDoc | FL_NULLABLE | ) |
Returns the FLSliceResult data owned by the document, if any, else a null slice.
FLEECE_PUBLIC void * FLDoc_GetAssociated | ( | FLDoc FL_NULLABLE | doc, |
const char * | type | ||
) |
Returns the pointer associated with the document.
You can use this together with FLValue_FindDoc to associate your own object with Fleece values, for instance to find your object that "owns" a value: myDoc = (app::Document*)FLDoc_GetAssociated(FLValue_FindDoc(val), "app::Document");
.
doc | The FLDoc to get a pointer from. |
type | The type of object expected, i.e. the same string literal passed to FLDoc_SetAssociated. |
FLEECE_PUBLIC FLSlice FLDoc_GetData | ( | FLDoc | FL_NULLABLE | ) |
Returns the encoded Fleece data backing the document.
FLEECE_PUBLIC FLValue FLDoc_GetRoot | ( | FLDoc | FL_NULLABLE | ) |
Returns the root value in the FLDoc, usually an FLDict.
FLEECE_PUBLIC FLSharedKeys FLDoc_GetSharedKeys | ( | FLDoc | FL_NULLABLE | ) |
Returns the FLSharedKeys used by this FLDoc, as specified when it was created.
FLEECE_PUBLIC void FLDoc_Release | ( | FLDoc | FL_NULLABLE | ) |
Releases a reference to an FLDoc.
This must be called once to free an FLDoc you created.
FLEECE_PUBLIC FLDoc FLDoc_Retain | ( | FLDoc | FL_NULLABLE | ) |
Adds a reference to an FLDoc.
This extends its lifespan until at least such time as you call FLRelease to remove the reference.
FLEECE_PUBLIC bool FLDoc_SetAssociated | ( | FLDoc FL_NULLABLE | doc, |
void *FL_NULLABLE | pointer, | ||
const char * | type | ||
) |
Associates an arbitrary pointer value with a document, and thus its contained values.
Allows client code to associate its own pointer with this FLDoc and its Values, which can later be retrieved with FLDoc_GetAssociated. For example, this could be a pointer to an app::Document
object, of which this Doc's root FLDict is its properties. You would store it by calling FLDoc_SetAssociated(doc, myDoc, "app::Document");
.
doc | The FLDoc to store a pointer in. |
pointer | The pointer to store in the FLDoc. |
type | A C string literal identifying the type. This is used to avoid collisions with unrelated code that might try to store a different type of value. |
NODISCARD FLEECE_PUBLIC FLDoc FL_NULLABLE FLValue_FindDoc | ( | FLValue | FL_NULLABLE | ) |
Looks up the Doc containing the Value, or NULL if there is none.
