The SecondaryHashDatabaseConfig type exposes the following members.

Constructors

  NameDescription
SecondaryHashDatabaseConfig
Instantiate a new SecondaryHashDatabaseConfig object

Methods

  NameDescription
Equals
Determines whether the specified Object is equal to the current Object.
(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.)
SetForeignKeyConstraintOverloaded.
ToString
Returns a string that represents the current object.
(Inherited from Object.)

Fields

  NameDescription
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.)
Compare
The Secondary Hash key comparison function.
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
(Inherited from DatabaseConfig.)
FreeThreaded
Cause the database object to be free-threaded; that is, concurrently usable by multiple threads in the address space.
(Inherited from DatabaseConfig.)
HashFunction
A user-defined hash function; if no hash function is specified, a default hash function is used.
ImmutableKey
If true, the secondary key is immutable.
(Inherited from SecondaryDatabaseConfig.)
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.)
Populate
If true and the secondary database is empty, walk through Primary and create an index to it in the empty secondary. This operation is potentially very expensive.
(Inherited from SecondaryDatabaseConfig.)
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

  NameDescription
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.
ForeignKeyDatabase
The database used to check the foreign key integrity constraint.
(Inherited from SecondaryDatabaseConfig.)
ForeignKeyNullfier
The nullifying function used to set the foreign key to null.
(Inherited from SecondaryDatabaseConfig.)
KeyGen
The delegate that creates the set of secondary keys corresponding to a given primary key and data pair.
(Inherited from SecondaryDatabaseConfig.)
OnForeignKeyDelete
The action taken when a referenced record in ForeignKeyDatabase is deleted.
(Inherited from SecondaryDatabaseConfig.)
PageSize
The size of the pages used to hold items in the database, in bytes.
(Inherited from DatabaseConfig.)
Primary
All updates to Primary will be automatically reflected in the secondary and all reads from the secondary will return corresponding data from Primary.
(Inherited from SecondaryDatabaseConfig.)
TableSize
An estimate of the final size of the hash table.
