The HeapDatabaseConfig type exposes the following members.
Constructors
Name | Description | |
---|---|---|
HeapDatabaseConfig |
Instantiate a new HeapDatabaseConfig 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.) | |
MaxSize |
Set the maximum on-disk database file size used by the database. If
this value is never set, the database's file size can grow without
bound. If this value is set, then the heap file can never grow
larger than the limit defined by this method. In that case, attempts
to update or create records in a database that has reached its
maximum size will throw a HeapFullException.
| |
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.) | |
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.) | |
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.) | |
MaxSizeBytes |
The bytes component of the maximum on-disk database file size.
| |
MaxSizeGBytes |
The gigabytes component of the maximum on-disk database file size.
| |
PageSize |
The size of the pages used to hold items in the database, in bytes.
(Inherited from DatabaseConfig.) | |
RegionSize |
The number of pages in a region of the database. If this value is
never set, the default region size for the database's page size will
be used. You can set the database page size using
PageSize.
If the database already exists, this value will be ignored. If the
specified region size is larger than the maximum region size for the
database's page size, an error will be returned when
Open(String, DatabaseConfig) is called. The maximum allowable region
size will be included in the error message.
