Enum Constant Details

INSTANCE

public static final Empty.EmptyISeq INSTANCE

Method Details

values

public static Empty.EmptyISeq[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static Empty.EmptyISeq valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null

iterator

public Iterator<Object> iterator()

Specified by:

iterator in interface BaseSeq<Object>

Specified by:

iterator in interface Iterable<Object>

subSeq

public ISeq<Object> subSeq(int start,
 int end)

Description copied from interface: Seq

Returns a view of the portion of this sequence between the specified start, inclusive, and end, exclusive. (If start and end are equal, the returned sequence has 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 a subsequence view instead of a whole sequence.

Specified by:

subSeq in interface ISeq<Object>

Specified by:

subSeq in interface Seq<Object>

Parameters:

start - low-end point (inclusive) of the sub-sequence.

end - high-end point (exclusive) of the sub-sequence.

Returns:

a view of the specified range within this sequence.

subSeq

public ISeq<Object> subSeq(int start)

Description copied from interface: Seq

Returns a view of the portion of this sequence between the specified start, inclusive, and end, exclusive. (If start and end are equal, the returned sequence has length zero.) The returned sequence is backed by this sequence, so non-structural changes in the returned sequence are reflected in this sequence, and vice-versa.

This method eliminates the need for explicit range operations (of the populationSort that commonly exist for arrays). Any operation that expects a sequence can be used as a range operation by passing a sub-sequence view instead of a whole sequence.

Specified by:

subSeq in interface ISeq<Object>

Specified by:

subSeq in interface Seq<Object>

Parameters:

start - lower end point (inclusive) of the sub array.

Returns:

a view of the specified range within this array.

get

public Object get(int index)

Description copied from interface: BaseSeq

Return the value at the given index.

Specified by:

get in interface BaseSeq<Object>

Parameters:

index - index of the element to return.

Returns:

the value at the given index.

length

public int length()

Description copied from interface: BaseSeq

Return the length of this sequence. Once the sequence is created, the length can't be changed.

Specified by:

length in interface BaseSeq<Object>

Returns:

the length of this sequence.

asList

public List<Object> asList()

Description copied from interface: Seq

Returns a fixed-size list backed by the specified sequence. (Changes to the returned list "write through" to the array.) The returned list is fixed size, serializable and implements RandomAccess.

Specified by:

asList in interface Seq<Object>

Returns:

a list view of this sequence

map

public <B> ISeq<B> map(Function<? super Object,? extends B> mapper)

Description copied from interface: Seq

Builds a new sequence by applying a function to all elements of this sequence.

Specified by:

map in interface ISeq<Object>

Specified by:

map in interface Seq<Object>

Type Parameters:

B - the element type of the returned collection.

Parameters:

mapper - the function to apply to each element.

Returns:

a new sequence of type That resulting from applying the given function f to each element of this sequence and collecting the results.

append
