Global comparison operator functions
These overloaded global operator functions perform the appropriate comparison operation between
queue container adaptors
x and
y.
Operations
== and
!= are performed by comparing the elements using algorithm
equal.
Operations
<,
>,
<= and
>= are performed by using algorithm
lexicographical_compare, which requires that the type of the elements (
T) has the
< operation (less-than) defined between two objects of that type.
These operators are overloaded in header
<queue>.
Parameters
- x, y
- queue container adaptors, having both the same template parameters (T and Container).
Return Value
true if the condition holds, and
false otherwise.
