Method Detail

array

public static LongArray array(long... longs)

Constructs an array of longs.

Parameters:

longs - each element

array

public static LongArray array()

Construct an empty LongArray

array

public static LongArray array(long value)

Construct a LongArray with one element.

Parameters:

value - the value

array

public static LongArray array(long value1,
                              long value2)

Construct a LongArray with two elements.

Parameters:

value1 - the first value

value2 - the second value

array

public static LongArray array(long value1,
                              long value2,
                              long value3)

Construct a LongArray with three elements.

Parameters:

value1 - the first value

value2 - the second value

value3 - the third value

array

public static LongArray array(long value1,
                              long value2,
                              long value3,
                              long value4)

Construct a LongArray with four elements.

Parameters:

value1 - the first value

value2 - the second value

value3 - the third value

value4 - the fourth value

equals

public boolean equals(Object other)

Test for equality with another object

Overrides:

equals in class ConstArray<Long>

Parameters:

other - the reference object with which to compare.

Returns:

true if the other object is a ConstArray with the same contents as this array

See Also:

Object.hashCode(), HashMap

hashCode

public int hashCode()

Computes a digest of the array for hashing. The hash code is the same as Arrays.hashCode(Object[]) called on a Java array containing the same elements.

Specified by:

hashCode in interface Selfless

Overrides:

hashCode in class ConstArray<Long>

Returns:

a hash code based on the contents of this array

See Also:

Object.equals(java.lang.Object), System.identityHashCode(java.lang.Object)

toString

public String toString()

Return a string representation of the array

Overrides:

toString in class ConstArray<Long>

Returns:

a string representation of this array

length

public int length()

Gets the length of the array.

Overrides:

length in class ConstArray<Long>

get

public Long get(int i)

Creates a Long for a specified long.

Overrides:

get in class ConstArray<Long>

Parameters:

i - position of the element to return

Throws:

ArrayIndexOutOfBoundsException - i is out of bounds

toArray

public <T> T[] toArray(T[] prototype)

Return a mutable copy of the array

Overrides:

toArray in class ConstArray<Long>

Parameters:

prototype - prototype of the array to copy into

Returns:

an array containing the contents of this ConstArray of the same type as prototype

Throws:

ArrayStoreException - if an element cannot be stored in the array

with

public LongArray with(Long newLong)

Creates a LongArray with an appended Long.

Overrides:

with in class PowerlessArray<Long>

Parameters:

newLong - the element to append

Returns:

the new array

Throws:

NullPointerException - newLong is null

getLong

public long getLong(int i)

Gets the long at a specified position.

Parameters:

i - position of the element to return

Throws:

ArrayIndexOutOfBoundsException - i is out of bounds

toLongArray

public long[] toLongArray()

Creates a mutable copy of the long array

with

public LongArray with(long newLong)

Creates a LongArray with an appended long.

Parameters:

newLong - the element to append

without

public LongArray without(int i)

Return a new LongArray that contains the same elements as this one excluding the element at a specified index

Overrides:

without in class PowerlessArray<Long>

Parameters:

i - the index of the element to exclude

Returns:

the new array

builder

public static LongArray.Builder builder()

Get a LongArray.Builder. This is equivalent to the constructor.

Returns:

a new builder instance, with the default internal array length

builder

public static LongArray.Builder builder(int estimate)

Get a LongArray.Builder. This is equivalent to the constructor.

Parameters:

estimate - estimated array length

Returns:

a new builder instance
