AddKey ( byte &key, byte &value, bool &WasUpdated, bool dontUpdateIfExists ) : byte[]
LTrieRootNode ( LTrie tree ) : System
RemoveAll ( bool withFileRecreation ) : void	Check TransactionCommit in case of RemoveAll with file Recreation. Note if some other threads are reading parallel data, exception will be thrown in their transaction. It's correct.
RemoveKey ( byte &key, bool &WasRemoved, bool retrieveDeletedValue, byte &deletedValue ) : void	Will return pointer to the value of the removing kid (if it existed). Otherwise NULL.

Method Details

AddKey() public method

public AddKey ( byte &key, byte &value, bool &WasUpdated, bool dontUpdateIfExists ) : byte[]
key	byte
value	byte
WasUpdated	bool	true means that value existed and was updated
dontUpdateIfExists	bool	When true - if value exists, we dont update it. If WasUpdated = true then we value exists, if false - we have inserted new one
return	byte[]

LTrieRootNode() public method

public LTrieRootNode ( LTrie tree ) : System
tree	LTrie
return	System

RemoveAll() public method

Check TransactionCommit in case of RemoveAll with file Recreation. Note if some other threads are reading parallel data, exception will be thrown in their transaction. It's correct.

public RemoveAll ( bool withFileRecreation ) : void
withFileRecreation	bool
return	void

RemoveKey() public method

Will return pointer to the value of the removing kid (if it existed). Otherwise NULL.

public RemoveKey ( byte &key, bool &WasRemoved, bool retrieveDeletedValue, byte &deletedValue ) : void
key	byte
WasRemoved	bool	indicates that value existed if true
retrieveDeletedValue	bool	indicates if we should bind deleted value to the result
deletedValue	byte	interesting only if WasRemoved = true and retrieveDeletedValue is true
return	void
