The HashDatabaseConfig type exposes the following members.
Constructors
Name | Description | |
---|---|---|
HashDatabaseConfig |
Instantiate a new HashDatabaseConfig object
|
Methods
Name | Description | |
---|---|---|
Equals | (Inherited from Object.) | |
GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) | |
GetType | Gets the type of the current instance. (Inherited from Object.) | |
SetEncryption |
Set the password and algorithm used by the Berkeley DB library to
perform encryption and decryption.
(Inherited from DatabaseConfig.) | |
ToString | Returns a string that represents the current object. (Inherited from Object.) |
Fields
Name | Description | |
---|---|---|
AutoCommit |
Enclose the open call within a transaction. If the call succeeds,
the open operation will be recoverable and all subsequent database
modification operations based on this handle will be transactionally
protected. If the call fails, no database will have been created.
(Inherited from DatabaseConfig.) | |
ByteOrder |
The byte order for integers in the stored database metadata. The
host byte order of the machine where the Berkeley DB library was
compiled is the default value.
(Inherited from DatabaseConfig.) | |
CacheSize |
The size of the shared memory buffer pool -- that is, the cache.
(Inherited from DatabaseConfig.) | |
Creation |
The policy for how to handle database creation.
| |
DoChecksum |
If true, do checksum verification of pages read into the cache from
the backing filestore.
(Inherited from DatabaseConfig.) | |
DuplicateCompare |
The duplicate data item comparison function.
| |
Duplicates |
Policy for duplicate data items in the database; that is, insertion
when the key of the key/data pair being inserted already exists in
the database will be successful.
| |
Env |
The Berkeley DB environment within which to create a database. If
null, the database will be created stand-alone; that is, it is not
part of any Berkeley DB environment.
(Inherited from DatabaseConfig.) | |
ErrorFeedback |
The mechanism for reporting error messages to the application.
(Inherited from DatabaseConfig.) | |
ErrorPrefix |
The prefix string that appears before error messages issued by
Berkeley DB.
(Inherited from DatabaseConfig.) | |
Feedback | ||
FreeThreaded |
Cause the database object to be free-threaded; that is, concurrently
usable by multiple threads in the address space.
(Inherited from DatabaseConfig.) | |
HashComparison |
The Hash key comparison function.
| |
HashFunction |
A user-defined hash function; if no hash function is specified, a
default hash function is used.
| |
NoMMap |
Do not map this database into process memory.
(Inherited from DatabaseConfig.) | |
NonDurableTxns |
If true, Berkeley DB will not write log records for this database.
(Inherited from DatabaseConfig.) | |
NoWaitDbExclusiveLock |
Configuration of BaseDatabase handle to obtain a write
lock on the entire database.
(Inherited from DatabaseConfig.) | |
Priority |
The cache priority for pages referenced by the database.
(Inherited from DatabaseConfig.) | |
ReadOnly |
Open the database for reading only. Any attempt to modify items in
the database will fail, regardless of the actual permissions of any
underlying files.
(Inherited from DatabaseConfig.) | |
ReadUncommitted |
Support transactional read operations with degree 1 isolation.
(Inherited from DatabaseConfig.) | |
Truncate |
Physically truncate the underlying file, discarding all previous databases it might have held.
(Inherited from DatabaseConfig.) | |
UseMVCC |
Open the database with support for multiversion concurrency control.
(Inherited from DatabaseConfig.) |
Properties
Name | Description | |
---|---|---|
EncryptAlgorithm |
The algorithm used to perform encryption and decryption.
(Inherited from DatabaseConfig.) | |
Encrypted |
Encrypt the database using the cryptographic password specified by
DatabaseConfig.SetEncryption or
DatabaseEnvironmentConfig.SetEncryption.
(Inherited from DatabaseConfig.) | |
EncryptionPassword |
The password used to perform encryption and decryption.
(Inherited from DatabaseConfig.) | |
FillFactor |
The desired density within the hash table. If no value is specified,
the fill factor will be selected dynamically as pages are filled.
| |
PageSize |
The size of the pages used to hold items in the database, in bytes.
(Inherited from DatabaseConfig.) | |
TableSize |
An estimate of the final size of the hash table.
