| Modifier and Type | Method and Description |
|---|---|
ISeq<T> |
append(Iterable<? extends T> values)
Return a new
Seq with the given values appended. |
default ISeq<T> |
append(T... values)
Return a new
Seq with the given values appended. |
MSeq<T> |
copy()
Return a shallow copy of this sequence.
|
static <T> ISeq<T> |
empty()
Return an empty
ISeq. |
<B> ISeq<B> |
map(Function<? super T,? extends B> mapper)
Builds a new sequence by applying a function to all elements of this
sequence.
|
static <T> ISeq<T> |
of(Iterable<? extends T> values)
Create a new
ISeq from the given values. |
static <T> ISeq<T> |
of(Supplier<? extends T> supplier,
int length)
Creates a new sequence, which is filled with objects created be the given
supplier. |
static <T> ISeq<T> |
of(T... values)
Create a new
ISeq from the given values. |
ISeq<T> |
prepend(Iterable<? extends T> values)
Return a new
Seq with the given values prepended. |
default ISeq<T> |
prepend(T... values)
Return a new
Seq with the given values prepended. |
ISeq<T> |
subSeq(int start)
Returns a view of the portion of this sequence between the specified
start, inclusive, and end, exclusive. |
ISeq<T> |
subSeq(int start,
int end)
Returns a view of the portion of this sequence between the specified
start, inclusive, and end, exclusive. |
static <T> Collector<T,?,ISeq<T>> |
toISeq()
Returns a
Collector that accumulates the input elements into a
new ISeq. |
static <A,B extends A> |
upcast(ISeq<B> seq)
Allows a safe (without compile warning) upcast from
B to
A. |

Seqstart, inclusive, and end, exclusive. (If start
and end are equal, the returned sequence has the length zero.)
The returned sequence is backed by this sequence, so non-structural
changes in the returned sequence are reflected in this array, and
vice-versa.
This method eliminates the need for explicit range operations (of the populationSort that commonly exist for arrays). Any operation that expects an array can be used as a range operation by passing an sub sequence view instead of an whole sequence.
