cl.distributeddatamgr.1 Change of int (*close)(OH_Cursor *cursor) in OH_Cursor Struct to int (*destroy)(OH_Cursor *cursor)

Change Impact

This change is incompatible with earlier versions. The function pointer name is changed from close to destroy. The input parameters and return values remain unchanged.

Key API/Component Changes

Before change:

 int (*close)(OH_Cursor *cursor);

After change:

 int (*destroy)(OH_Cursor *cursor);

Adaptation Guide Example:

Code before change:

cursor->close(cursor);

Code after change:

cursor->destroy(cursor);

cl.distributeddatamgr.2 Change of int (*destroyPredicates)(OH_Predicates *predicates) in OH_Predicates Struct to int (*destroy)(OH_Predicates *predicates)

Change Impact

This change is incompatible with earlier versions. The function pointer name is changed from destroyPredicates to destroy. The input parameters and return values remain unchanged.

Key API/Component Changes

Before change:

int (*destroyPredicates)(OH_Predicates *predicates);

int (*destroy)(OH_Predicates *predicates);

Adaptation Guide Example:

Code before change:

predicates->destroyPredicates(predicates);

Code after change:

predicates->destroy(predicates);

cl.distributeddatamgr.3 Change of int (*destroyValueObject)(OH_VObject *valueObject) in OH_VObject Struct to int (*destroy)(OH_VObject *valueObject)

Change Impact

valueObject->destroy(valueObject);

cl.distributeddatamgr.4 Change of int (*destroyValuesBucket)(OH_VBucket *bucket) in OH_VBucket Struct to int (*destroy)(OH_VBucket *bucket)

Change Impact

This change is incompatible with earlier versions. The function pointer name is changed from destroyValuesBucket to destroy. The input parameters and return values remain unchanged.

Key API/Component Changes

Before change:

int (*destroyValuesBucket)(OH_VBucket *bucket);

After change:

int (*destroy)(OH_VBucket *bucket);

Adaptation Guide Example:

Code before change:

valueBucket->destroyValuesBucket(valueBucket);

Code after change:

 valueBucket->destroy(valueBucket);

cl.distributeddatamgr.5 Change of OH_Rdb_Config Struct Member Variables

Change Impact

The changes are incompatible with earlier versions.
The type of securityLevel is changed from enum OH_Rdb_SecurityLevel to in.
The member variable path is deleted.
The member variables selfSize, dataBaseDir, storeName, bundleName, and moduleName are added.

Key API/Component Changes

OH_Rdb_Config before change:

typedef struct {
    const char *path;
    bool isEncrypt;
    enum OH_Rdb_SecurityLevel securityLevel;
} OH_Rdb_Config;

OH_Rdb_Config after change:

typedef struct {
    int selfSize;
    const char *dataBaseDir;
    const char *storeName;
    const char *bundleName;
    const char *moduleName;
    bool isEncrypt;
    int securityLevel;
} OH_Rdb_Config;

Adaptation Guide When creating an RDB store with OH_Rdb_Config, you need to pass in the bundle name and module name.

cl.distributeddatamgr.6 Change of const char *path in OH_Rdb_DeleteStore() to const OH_Rdb_Config *config

Change Impact

This change is incompatible with earlier versions. The input parameter is changed from const char *path to const OH_Rdb_Config *config.

Key API/Component Changes

OH_Rdb_DeleteStore before change:

int OH_Rdb_DeleteStore(const char *path);

OH_Rdb_DeleteStore after change:

int OH_Rdb_DeleteStore(const OH_Rdb_Config *config);

Adaptation Guide

Example:
