HH\ImmVector::take
Returns an ImmVector containing the first $n values of the current
ImmVector
public function take(
int $n,
): ImmVector<Tv>;
The returned ImmVector will always be a subset (but not necessarily a
proper subset) of the current ImmVector. If $n is greater than the
length of the current ImmVector, the returned ImmVector will contain
all elements of the current ImmVector.
$n is 1-based. So the first element is 1, the second 2, etc.
Parameters
int $n- The last element that will be included in the returnedImmVector.
Returns
ImmVector<Tv>- AnImmVectorthat is a subset of the currentImmVectorup to$nelements.
