The BTreeDatabaseConfig type exposes the following members.
Constructors
Name | Description | |
---|---|---|
BTreeDatabaseConfig |
Create a new BTreeDatabaseConfig 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.) | |
SetCompression | Overloaded. | |
SetEncryption |
Set the password and algorithm used by the Berkeley DB library to
perform encryption and decryption.
(Inherited from DatabaseConfig.) | |
ToString | (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.) | |
BTreeCompare |
The Btree key comparison function.
| |
BTreePrefixCompare |
The Btree prefix function.
| |
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.) | |
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.) | |
NoReverseSplitting |
Turn reverse splitting in the Btree on or off.
| |
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.) | |
UseRecordNumbers |
If true, support retrieval from the Btree using record numbers.
|
Properties
Name | Description | |
---|---|---|
Compress |
The compression function used to store key/data pairs in the
database.
| |
Decompress |
The decompression function used to retrieve key/data pairs from the
database.
| |
EncryptAlgorithm |
The algorithm used to perform encryption and decryption.
(Inherited from DatabaseConfig.) | |
EncryptionPassword |
The password used to perform encryption and decryption.
(Inherited from DatabaseConfig.) | |
MinKeysPerPage |
The minimum number of key/data pairs intended to be stored on any
single Btree leaf page.
| |
PageSize |
The size of the pages used to hold items in the database, in bytes.
(Inherited from DatabaseConfig.) |
