C# Class GSF.Collections.BitArray

Provides an array of bits. Much like the native .NET implementation, however this focuses on providing a free space bit array.

Public Methods

Method	Description
AreAllBitsCleared ( int index, int length ) : bool	Determines if any of the provided bits are cleared.
AreAllBitsSet ( int index, int length ) : bool	Determines if any of the provided bits are set.
BitArray ( bool initialState, int count = BitsPerElement ) : System	Initializes BitArray.
ClearAll ( ) : void	Clears all bits.
ClearBit ( int index ) : void	Sets the corresponding bit to false
ClearBits ( int index, int length ) : void	Clears a series of bits
EnsureCapacity ( int capacity ) : void	Verifies that the BitArray has the capacity to store the provided number of elements. If not, the bit array will autogrow by a factor of 2 or at least the capacity
FindClearedBit ( ) : int	Returns the index of the first bit that is cleared. -1 is returned if all bits are set.
FindSetBit ( ) : int	Returns the index of the first bit that is set. -1 is returned if all bits are set.
GetAllClearedBits ( ) : IEnumerable	Yields a list of all bits that are cleared.
GetAllSetBits ( ) : IEnumerable	Yields a list of all bits that are set.
GetBit ( int index ) : bool	Gets the status of the corresponding bit.
SetAll ( ) : void	Sets all bits.
SetBit ( int index ) : void	Sets the corresponding bit to true
SetBits ( int index, int length ) : void	Sets a series of bits
SetCapacity ( int capacity ) : void	Increases the capacity of the bit array. Decreasing capacity is currently not supported
TryClearBit ( int index ) : bool	Sets the corresponding bit to false. Returns true if the bit state was changed. True if the bit state was changed. False if the bit was already cleared.
TrySetBit ( int index ) : bool	Sets the corresponding bit to true. Returns true if the bit state was changed. True if the bit state was changed. False if the bit was already set.
this ( int index ) : bool	Gets/Sets individual bits in this array.

length	int	the length of the run
return	bool

BitArray() public method

Initializes BitArray.

public BitArray ( bool initialState, int count = BitsPerElement ) : System
initialState	bool	Set to true to initial will all elements set. False to have all elements cleared.
count	int	The number of bit positions to support
