RecnoDatabase Properties

BerkeleyDB

The RecnoDatabase type exposes the following members.

Properties

  NameDescription
AppendCallback
A function to call after the record number has been selected but before the data has been stored into the database.
AutoCommit
If true, all database modification operations based on this object will be transactionally protected.
(Inherited from BaseDatabase.)
CacheSize
The size of the shared memory buffer pool -- that is, 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.)
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; that is, 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.)
NoMMap

If true, this database is not mapped into process memory.

See MMapSize for further information.

(Inherited from BaseDatabase.)
NonDurableTxns
If true, Berkeley DB will not write log records for this database.
(Inherited from BaseDatabase.)
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 reading 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.)
RecordDelimiter
The delimiting byte used to mark the end of a record in SourceFile.
RecordLength
If using fixed-length, not byte-delimited records, the length of the records.
RecordPad
The padding character for short, fixed-length records.
Renumber
If true, the logical record numbers are mutable, and change as records are added to and deleted from the database.
Snapshot
If true, any SourceFile file will be read in its entirety when Open(String, RecnoDatabaseConfig) is called. If false, SourceFile may be read lazily.
SourceFile
The underlying source file for the Recno access method.
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.
(Inherited from BaseDatabase.)
