The SecondaryQueueDatabase type exposes the following members.
Properties
Name | Description | |
---|---|---|
AutoCommit |
If true, all database modification operations based on this object
are transactionally protected.
(Inherited from BaseDatabase.) | |
CacheSize |
The size of the shared memory buffer pool (the cache).
(Inherited from BaseDatabase.) | |
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.) | |
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.) | |
ExtentSize |
The size of the extents used to hold pages in a
QueueDatabase, specified as a number of pages.
| |
Feedback |
Monitor progress within long running operations.
(Inherited from BaseDatabase.) | |
FileName |
The filename of this database, if it has one.
(Inherited from BaseDatabase.) | |
FreeThreaded |
If true, the object is free-threaded; concurrently usable
by multiple threads in the address space.
(Inherited from BaseDatabase.) | |
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.) | |
KeyGen |
The delegate that creates the set of secondary keys corresponding to
a given primary key and data pair.
(Inherited from SecondaryDatabase.) | |
Length |
The length of records in the database.
| |
messageFeedback |
The mechanism for reporting detailed statistic messages to the
application.
(Inherited from BaseDatabase.) | |
MessagePrefix |
The prefix string that appears before informational messages issued
by Berkeley DB.
(Inherited from BaseDatabase.) | |
Msgfile |
The message file.
(Inherited from BaseDatabase.) | |
NoMMap | If true, this database is not mapped into process memory. See MMapSize for further information. | |
NonDurableTxns |
If true, Berkeley DB does not write log records for this database.
(Inherited from BaseDatabase.) | |
NoWaitDbExclusiveLock |
If true, configure the database handle to obtain a write lock on the
entire database. When the database is opened it immediately
throws LockNotGrantedException if it cannot obtain the
exclusive lock immediately. If False, configure the database handle
to obtain a write lock on the entire database. When the database is
opened, it blocks until it can obtain the exclusive lock. If
null, do not configure the database handle to obtain a write lock on
the entire database.
(Inherited from BaseDatabase.) | |
Nullifier |
The nullifying function used to set the foreign key to null.
(Inherited from SecondaryDatabase.) | |
PadByte |
The padding character for short, fixed-length records.
| |
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 read 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.) | |
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.
