Exceptions

Definition at line 300 of file netstorage.hpp.

◆ TInstance [1/4] ◆ TInstance [2/4] ◆ TInstance [3/4] ◆ TInstance [4/4] ◆ TNetStorageFlags ◆ TNetStorageProgressCb ◆ EErrCode Enumerator eInvalidArg

Timeout encountered while performing an op.

Operation has been interrupted.

eUnknown

Unknown error.

Definition at line 69 of file netstorage.hpp.

◆ ENetStorageFlags

Blob storage allocation and access strategy.

Enumerator fNST_NetCache

Use NetCache as the primary storage.

fNST_FileTrack

Use FileTrack as the primary storage.

fNST_V1 fNST_V2 fNST_Fast fNST_Persistent fNST_AnyLoc

Any location (all location bits are set)

fNST_Movable

Allow the object to move between storages.

fNST_Cacheable

Has no effect at the moment.

fNST_NoMetaData

Do not use NetStorage relational database to track ownership & changes.

Attributes and querying will also be disabled.

fNST_V3 fNST_V4 fNST_AnyAttr

Definition at line 129 of file netstorage.hpp.

◆ ENetStorageObjectLocation

Enumeration that indicates the current location of the object.

Enumerator eNFL_Unknown eNFL_NotFound eNFL_NetCache eNFL_FileTrack

Definition at line 86 of file netstorage.hpp.

◆ ENetStorageRemoveResult ◆ Close() void CNetStorageObject::Close ( void )

Finalize and close the current object stream.

If the operation is successful, then the state (including the current position, if applicable) of the 'CNetStorageObject' is reset, and you can start reading from (or writing to) the object all anew, as if the 'CNetStorageObject' object had just been created by 'CNetStorage'.

◆ CNetStorage() [1/3]

Construct a CNetStorage object.

Parameters

init_string Initialization string that contains client identification, network service locations, etc. The string must be a sequence of apersand-separated pairs of attribute names and their values. Within each pair, the name and the value of the attribute must be separated by the equality sign, and the value must be URL-encoded. The following attributes are recoginzed: * namespace - Application domain. This parameter is required. * client - Application name. If omitted, generated from the executable pathname. * nst - NetStorage server address or LBSM service name pointing to a group of NetStorage servers. * metadata - Whether to request or disable the metadata DB. Valid options:

required - Database access must be enabled for the specified NetStorage service name in the server configuration.
disabled - Database access is disabled for all operations.
monitoring - Read-only access to the metadata database. * nc - NetCache service name or server address. * cache - Synonym for "namespace". Example: "client=MyApp&nst=NST_Test&nc=NC_MyApp_TEST&cache=myapp"

default_flags Default storage preferences for the created objects.

◆ CNetStorage() [2/3] ◆ CNetStorage() [3/3] ◆ CNetStorageByKey() [1/3]

Construct a CNetStorageByKey object.

Parameters: init_string Initialization string that contains client identification, network service locations, etc. The string must be a sequence of apersand-separated pairs of attribute names and their values. Within each pair, the name and the value of the attribute must be separated by the equality sign, and the value must be URL-encoded. The following attributes are recoginzed: * namespace - Namespace name, within which the keys passed to the methods of this class must be unique. This parameter is required. * domain - Synonym for "namespace". * client - Application name. * nst - NetStorage server address or LBSM service name pointing to a group of NetStorage servers. Example: "client=MyApp&nst=NST_Test&namespace=myapp" default_flags Default storage preferences for objects created by this object.

◆ GetInfo() ◆ GetLoc() string CNetStorageObject::GetLoc ( void ) const ◆ GetLocation() TLocation CNetStorageObjectInfo::GetLocation ( void ) const

Return a ENetStorageObjectLocation constant that corresponds to the storage back-end where the object currently resides.

If the object cannot be found in any of the predictable locations, eNFL_NotFound is returned. If the object is found, the returned value reflects the storage back-end that supplied the rest of information about the object.

Relocate a object according to the specified combination of flags.

Parameters: object_loc An existing object to relocate flags Combination of flags that defines the new object location (storage) cb Relocation progress callback (

See also: TNetStorageProgressCb). CJsonNode input argument (object) will contain two subnodes: number 'BytesRelocated' and string 'Message'

Returns: New object ID that fully reflects the new object location. If possible, this new ID should be used for further access to the object. Note however that its original ID still can be used as well.
