Compares two contiguous containers using a predicate to compare pairs of projected elements. Whether the containers are the same size and the predicate returned true for every pair of elements.
Parameters
| Name | Description |
|---|---|
| InputA | Container of elements that are used as the first argument to the predicate. |
| InputB | Container of elements that are used as the second argument to the predicate. |
| Projection | Projection to apply to the elements before comparing them. |
| Predicate | Condition which returns true for elements which are deemed equal. |
