Public Methods

Method	Description
AddAndGet ( long value ) : long	Increments the sequence and stores the result, as an atomic operation.
CompareAndSet ( long expectedSequence, long nextSequence ) : bool	Atomically set the value to the given updated value if the current value == the expected value.
IncrementAndGet ( ) : long	Increments the sequence and stores the result, as an atomic operation.
Sequence ( long initialValue = InitialCursorValue ) : System.Runtime.InteropServices	Construct a new sequence counter that can be tracked across threads.
SetValue ( long value ) : void	Perform an ordered write of this sequence. The intent is a Store/Store barrier between this write and any previous store.
SetValueVolatile ( long value ) : void	Performs a volatile write of this sequence. The intent is a Store/Store barrier between this write and any previous write and a Store/Load barrier between this write and any subsequent volatile read.
ToString ( ) : string	Value of the Sequence as a String.

Method Details

AddAndGet() public method

Increments the sequence and stores the result, as an atomic operation.

public AddAndGet ( long value ) : long
value	long
return	long

CompareAndSet() public method

Atomically set the value to the given updated value if the current value == the expected value.

public CompareAndSet ( long expectedSequence, long nextSequence ) : bool
expectedSequence	long	the expected value for the sequence
nextSequence	long	the new value for the sequence
return	bool

IncrementAndGet() public method

Increments the sequence and stores the result, as an atomic operation.

public IncrementAndGet ( ) : long
return	long

Sequence() public method

Construct a new sequence counter that can be tracked across threads.

public Sequence ( long initialValue = InitialCursorValue ) : System.Runtime.InteropServices
initialValue	long	initial value for the counter
return	System.Runtime.InteropServices

SetValue() public method

Perform an ordered write of this sequence. The intent is a Store/Store barrier between this write and any previous store.

public SetValue ( long value ) : void
value	long	The new value for the sequence.
return	void

SetValueVolatile() public method

Performs a volatile write of this sequence. The intent is a Store/Store barrier between this write and any previous write and a Store/Load barrier between this write and any subsequent volatile read.

public SetValueVolatile ( long value ) : void
value	long
return	void

ToString() public method

Value of the Sequence as a String.

public ToString ( ) : string
return	string
