The HashDatabase type exposes the following members.
Properties
| Name | Description | |
|---|---|---|
 | AutoCommit |
If true, all database modification operations based on this object
will be transactionally protected.
(Inherited from BaseDatabase.) |
| CacheSize |
The size of the shared memory buffer pool -- that is, the cache.
(Inherited from BaseDatabase.) |
| Compare |
The Hash key comparison function. The comparison function is called
whenever it is necessary to compare a key specified by the
application with a key currently stored in the tree.
|
| Creation |
The CreatePolicy with which this database was opened.
(Inherited from BaseDatabase.) |
| DatabaseName |
The name of this database, if it has one.
(Inherited from BaseDatabase.) |
| DoChecksum |
If true, do checksum verification of pages read into the cache from
the backing filestore.
(Inherited from BaseDatabase.) |
| DupCompare |
The duplicate data item comparison function.
|
| Duplicates |
Whether the insertion of duplicate data items in the database is
permitted, and whether duplicates items are sorted.
|
| EncryptAlgorithm |
The algorithm used by the Berkeley DB library to perform encryption
and decryption.
(Inherited from BaseDatabase.) |
| Encrypted |
If true, encrypt all data stored in the database.
(Inherited from BaseDatabase.) |
| Endianness |
The database byte order.
(Inherited from BaseDatabase.) |
| ErrorFeedback |
The mechanism for reporting detailed error messages to the
application.
(Inherited from BaseDatabase.) |
| ErrorPrefix |
The prefix string that appears before error messages issued by
Berkeley DB.
(Inherited from BaseDatabase.) |
| Feedback |
Monitor progress within long running operations.
(Inherited from BaseDatabase.) |
| FileName |
The filename of this database, if it has one.
(Inherited from BaseDatabase.) |
| FillFactor |
The desired density within the hash table.
|
| FreeThreaded |
If true, the object is free-threaded; that is, concurrently usable
by multiple threads in the address space.
(Inherited from BaseDatabase.) |
| HashFunction |
A user-defined hash function; if no hash function is specified, a
default hash function is used.
|
| HasMultiple |
If true, the object references a physical file supporting multiple
databases.
(Inherited from BaseDatabase.) |
| InHostOrder |
If true, the underlying database files were created on an
architecture of the same byte order as the current one. This
information may be used to determine whether application data needs
to be adjusted for this architecture or not.
(Inherited from BaseDatabase.) |
| NoMMap | If true, this database is not mapped into process memory. See MMapSize for further information. |
| NonDurableTxns |
If true, Berkeley DB will not write log records for this database.
(Inherited from BaseDatabase.) |
| Pagesize |
The database's current page size.
(Inherited from BaseDatabase.) |
| Priority |
The cache priority for pages referenced by this object.
(Inherited from BaseDatabase.) |
| ReadOnly |
If true, this database has been opened for reading only. Any attempt
to modify items in the database will fail, regardless of the actual
permissions of any underlying files.
(Inherited from BaseDatabase.) |
| ReadUncommitted |
If true, this database supports transactional read operations with
degree 1 isolation. Read operations on the database may request the
return of modified but not yet committed data.
(Inherited from BaseDatabase.) |
| TableSize |
An estimate of the final size of the hash table.
|
| Transactional |
If true, this database has been opened in a transactional mode.
(Inherited from BaseDatabase.) |
| Truncated |
If true, the underlying file was physically truncated upon open,
discarding all previous databases it might have held.
(Inherited from BaseDatabase.) |
| Type |
The type of the underlying access method (and file format). This
value may be used to determine the type of the database after an
Open(String, DatabaseConfig).
(Inherited from BaseDatabase.) |
| UseMVCC |
If true, the database was opened with support for multiversion
concurrency control.
(Inherited from BaseDatabase.) |
