| | Name | Description |
|---|
 | BTreeOrder | A quick means of setting all the min/max values for the node counts using this value as a basis for the Maximum fields and one-quarter of this value for Minimum fields provided the result is in range. (Inherited from CSharpTest.Net.Collections.BPlusTreeOptions<TKey,TValue>) |
| CacheKeepAliveFactory | CacheKeepAliveFactory provides a delegate to inject an implementation of the IObjectKeepAlive interface while then igoring all the other CacheKeepAliveXXX properties. (Inherited from CSharpTest.Net.Collections.BPlusTreeOptions<TKey,TValue>) |
| CacheKeepAliveMaximumHistory | Determins maximum number of recently visited nodes to keep alive in memory. This number defines the history size, not the number of distinct nodes. The ceiling is always respected reguardless of the timeout. Specify a value of 0 to disable history keep alive. (Inherited from CSharpTest.Net.Collections.BPlusTreeOptions<TKey,TValue>) |
| CacheKeepAliveMinimumHistory | Determins minimum number of recently visited nodes to keep alive in memory. This number defines the history size, not the number of distinct nodes. This number will always be kept reguardless of the timeout. Specify a value of 0 to allow the timeout to empty the cache. (Inherited from CSharpTest.Net.Collections.BPlusTreeOptions<TKey,TValue>) |
| CacheKeepAliveTimeout | If the cache contains more that CacheKeepAliveMinimumHistory items, this timeout will start to remove those items until the cache history is reduced to CacheKeepAliveMinimumHistory. It is important to know that the BPlusTree itself contains no theads and this timeout will not be respected if cache is not in use. (Inherited from CSharpTest.Net.Collections.BPlusTreeOptions<TKey,TValue>) |
| CachePolicy | Determines how long loaded nodes stay in memory, Full keeps all loaded nodes alive and is the most efficient, The default Recent keeps recently visited nodes alive based on the CacheKeepAlive properties, and None does not cache the nodes at all but does maintain a cache of locks for each node visited. (Inherited from CSharpTest.Net.Collections.BPlusTreeOptions<TKey,TValue>) |
| CallLevelLock | Overridden. Defines a reader/writer lock that used to control exclusive tree access when needed. Version2 files using trasacation logs will use this to gain exclusive access to the tree during calls to Commit, Rollback, etc. The default is to use a SimpleReadWriteLocking class. If you are accessing the tree from a single thread, consider using the IgnoreLocking class for better performance. |
| CreateFile | Gets or sets the file-create policy used when backing with a file storage (Inherited from CSharpTest.Net.Collections.BPlusTreeOptions<TKey,TValue>) |
| ExistingLogAction | Defines the action to perform when opening a BPlusTree with an existing log file. |
| FileBlockSize | Gets or sets the number of bytes per file-block used in the file storage (Inherited from CSharpTest.Net.Collections.BPlusTreeOptions<TKey,TValue>) |
| FileName | Gets or sets the FileName that should be used to store the BTree (Inherited from CSharpTest.Net.Collections.BPlusTreeOptions<TKey,TValue>) |
| FileVersion | Overridden. Returns the version this option set is compatible with. |
| KeyComparer | Defines a custom IComparer<T> to be used for comparing keys (Inherited from CSharpTest.Net.Collections.BPlusTreeOptions<TKey,TValue>) |
| KeySerializer | Accesses the key serializer given to the constructor (Inherited from CSharpTest.Net.Collections.BPlusTreeOptions<TKey,TValue>) |
| LockingFactory | Gets or sets the locking factory to use for accessing shared data. The default is WriterOnlyLocking() which does not perform read locks, rather it will rely on the cache of the btree and may preform dirty reads. You can use any implementation of ILockFactory; however, the SimpleReadWriteLocking seems to perform the most efficiently for both reader/writer locks. Additionally wrapping that instance in a ReserveredWriterLocking() instance will allow reads to continue up until a writer begins the commit process. If you are only accessing the BTree instance from a single thread this can be set to IgnoreLocking. Be careful of using ReaderWriterLocking as the write-intesive nature of the BTree will suffer extreme performance penalties with this lock. (Inherited from CSharpTest.Net.Collections.BPlusTreeOptions<TKey,TValue>) |
| LockTimeout | Gets or sets the number of milliseconds to wait before failing a lock request, the default of two minutes should be more than adequate. (Inherited from CSharpTest.Net.Collections.BPlusTreeOptions<TKey,TValue>) |
| MaximumChildNodes | The largest number of child nodes that should be linked to before refactoring the tree to split this node into two. This property has a side-effect on MinimumChildNodes to ensure that it continues to be at most half of MaximumChildNodes. (Inherited from CSharpTest.Net.Collections.BPlusTreeOptions<TKey,TValue>) |
| MaximumValueNodes | The largest number of values that should be contained in this node before refactoring the tree to split this node into two. This property has a side-effect on MinimumValueNodes to ensure that it continues to be at most half of MaximumValueNodes. (Inherited from CSharpTest.Net.Collections.BPlusTreeOptions<TKey,TValue>) |
| MinimumChildNodes | The smallest number of child nodes that should be linked to before refactoring the tree to remove this node. In a 'normal' and/or purest B+Tree this is always half of max; however for performance reasons this B+Tree allow any value equal to or less than half of max but at least 2. (Inherited from CSharpTest.Net.Collections.BPlusTreeOptions<TKey,TValue>) |
| MinimumValueNodes | The smallest number of values that should be contained in this node before refactoring the tree to remove this node. In a 'normal' and/or purest B+Tree this is always half of max; however for performance reasons this B+Tree allow any value equal to or less than half of max but at least 2. (Inherited from CSharpTest.Net.Collections.BPlusTreeOptions<TKey,TValue>) |
| ReadOnly | Sets the BTree into a read-only mode (only supported when opening an existing file) (Inherited from CSharpTest.Net.Collections.BPlusTreeOptions<TKey,TValue>) |
| StoragePerformance | Returns the DurabilityProtection of the underlying storage to create. |
| StorageSystem | Sets the custom implementation of the storage back-end to use for the BTree (Inherited from CSharpTest.Net.Collections.BPlusTreeOptions<TKey,TValue>) |
| StorageType | Can be used to explicitly specify the storage type, or by simply providing a file name this will be done for you. If no file name was specified the default is to use a memory store. (Inherited from CSharpTest.Net.Collections.BPlusTreeOptions<TKey,TValue>) |
| TransactionLog | Gets or sets an implementation of ITransactionLog<TKey, TValue> used to log writes to this tree for recovery and/or monitoring. |
| TransactionLogFileName | Gets or sets a filename to write binary log files to. |
| TransactionLogLimit | Defines the number of bytes in the transaction log file before the BPlusTree will auto-commit and truncate the log. Values equal to or less than zero will not auto-commit (default). |
| ValueSerializer | Accesses the key serializer given to the constructor (Inherited from CSharpTest.Net.Collections.BPlusTreeOptions<TKey,TValue>) |
