Remarks

This class implements a vector of bits that grows as needed. Each component of the bit set has a boolean value. The bits of a BitSet are indexed by nonnegative integers. Individual indexed bits can be examined, set, or cleared. One BitSet may be used to modify the contents of another BitSet through logical AND, logical inclusive OR, and logical exclusive OR operations.

By default, all bits in the set initially have the value false.

Every bit set has a current size, which is the number of bits of space currently in use by the bit set. Note that the size is related to the implementation of a bit set, so it may change with implementation. The length of a bit set relates to logical length of a bit set and is defined independently of implementation.

Unless otherwise noted, passing a null parameter to any of the methods in a BitSet will result in a NullPointerException.

A BitSet is not safe for multithreaded use without external synchronization.

Constructors

BitSet()	Creates a new bit set.
BitSet(Int32)	Creates a bit set whose initial size is large enough to explicitly represent bits with indices in the range 0 through nbits-1.
BitSet(IntPtr, JniHandleOwnership)	A constructor used when creating managed representations of JNI objects; called by the runtime.

Properties

Class	Returns the runtime class of this Object. (Inherited from Object)
Handle	The handle to the underlying Android instance. (Inherited from Object)
IsEmpty	Returns true if this BitSet contains no bits that are set to true.
JniIdentityHashCode	(Inherited from Object)
JniPeerMembers
PeerReference	(Inherited from Object)
ThresholdClass	This API supports the Mono for Android infrastructure and is not intended to be used directly from your code.
ThresholdType	This API supports the Mono for Android infrastructure and is not intended to be used directly from your code.

Methods

And(BitSet)	Performs a logical <b>AND</b> of this target bit set with the argument bit set.
AndNot(BitSet)	Clears all of the bits in this BitSet whose corresponding bit is set in the specified BitSet.
Cardinality()	Returns the number of bits set to true in this BitSet.
Clear()	Sets all of the bits in this BitSet to false.
Clear(Int32, Int32)	Sets the bits from the specified fromIndex (inclusive) to the specified toIndex (exclusive) to false.
Clear(Int32)	Sets the bit specified by the index to false.
Clone()	Cloning this BitSet produces a new BitSet that is equal to it.
Dispose()	(Inherited from Object)
Dispose(Boolean)	(Inherited from Object)
Equals(Object)	Indicates whether some other object is "equal to" this one. (Inherited from Object)
Flip(Int32, Int32)	Sets each bit from the specified fromIndex (inclusive) to the specified toIndex (exclusive) to the complement of its current value.
Flip(Int32)	Sets the bit at the specified index to the complement of its current value.
Get(Int32, Int32)	Returns a new BitSet composed of bits from this BitSet from fromIndex (inclusive) to toIndex (exclusive).
