boost::dynamic_bitset::reference
A proxy class to simulate lvalues of bit type.
Description
This class exists only as a helper class for dynamic_bitset's operator[]. The following list describes the valid operations on the reference type. Assume that b is an instance of dynamic_bitset, i, j are of size_type and in the range [0, b.size())]. Also, note that when we write b[ i ] we mean an object of type reference that was initialized from b[ i ]. The variable x is a bool.
-
(bool)b[ i ]
Returns the i‐th bit of b.
-
(bool)~ b[ i ]
Returns the opposite of the i‐th bit of b.
-
b[ i ].flip()
Flips the i‐th bit of b and returns b[ i ].
-
x = b[ i ]
Assigns the i‐th bit of b to x.
-
b[ i ]= x
Sets the i‐th bit of b to the value of x and returns b[ i ].
-
b[ i ]= b[ j ]
Sets the i‐th bit of b to the value of the j‐th bit of b and returns b[ i ].
-
b[ i ]|= x
Does an OR of the i‐th bit of b with the value of x and returns b[ i ].
-
b[ i ]&= x
Does an AND of the i‐th bit of b with the value of x and returns b[ i ].
-
b[ i ]ˆ= x
Does a XOR of the i‐th bit of b with the value of x and returns b[ i ].
-
b[ i ]‐= x
If x is true, clears the i‐th bit of b. Returns `b[ i ]`.
-
b[ i ]|= b[ j ]
Does an OR of the i‐th bit of b with the j‐th bit of b and returns b[ i ].
-
b[ i ]&= b[ j ]
Does an AND of the i‐th bit of b with the j‐th bit of b and returns b[ i ].
-
b[ i ]ˆ= b[ j ]
Does a XOR of the i‐th bit of b with the j‐th bit of b and returns b[ i ].
-
b[ i ]‐= b[ j ]
If the j‐th bit of b is set, clears the i‐th bit of b. Returns b[ i ].
