Method Detail

array

public static IntArray array(int... ints)

Constructs an array of ints.

Parameters:

ints - each element

array

public static IntArray array()

Construct an empty IntArray

array

public static IntArray array(int value)

Construct a IntArray with one element.

Parameters:

value - the value

array

public static IntArray array(int value1,
                             int value2)

Construct a IntArray with two elements.

Parameters:

value1 - the first value

value2 - the second value

array

public static IntArray array(int value1,
                             int value2,
                             int value3)

Construct a IntArray with three elements.

Parameters:

value1 - the first value

value2 - the second value

value3 - the third value

array

public static IntArray array(int value1,
                             int value2,
                             int value3,
                             int value4)

Construct a IntArray with four elements.

Parameters:

value1 - the first value

value2 - the second value

value3 - the third value

value4 - the fourth value

equals

public boolean equals(java.lang.Object other)

Test for equality with another object

Overrides:

equals in class ImmutableArray<java.lang.Integer>

Returns:

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

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<java.lang.Integer>

Returns:

a hash code based on the contents of this array

toString

public java.lang.String toString()

Return a string representation of the array

Overrides:

toString in class ConstArray<java.lang.Integer>

Returns:

a string representation of this array

length

public int length()

Gets the length of the array.

Overrides:

length in class ConstArray<java.lang.Integer>

get

public java.lang.Integer get(int i)

Creates a Integer for a specified int.

Overrides:

get in class ConstArray<java.lang.Integer>

Parameters:

i - position of the element to return

Throws:

java.lang.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<java.lang.Integer>

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:

java.lang.ArrayStoreException - if an element cannot be stored in the array

with

public IntArray with(java.lang.Integer newInt)

Creates a IntArray with an appended Integer.

Overrides:

with in class PowerlessArray<java.lang.Integer>

Parameters:

newInt - the element to append

Returns:

the new array

Throws:

java.lang.NullPointerException - newInt is null

getInt

public int getInt(int i)

Gets the int at a specified position.

Parameters:

i - position of the element to return

Throws:

java.lang.ArrayIndexOutOfBoundsException - i is out of bounds

toIntArray

public int[] toIntArray()

Creates a mutable copy of the int array

with

public IntArray with(int newInt)

Creates a IntArray with an appended int.

Parameters:

newInt - the element to append

without

public IntArray without(int i)

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

Overrides:

without in class PowerlessArray<java.lang.Integer>

Parameters:

i - the index of the element to exclude

Returns:

the new array

builder

public static IntArray.Builder builder()

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

Returns:

a new builder instance, with the default internal array length

builder

public static IntArray.Builder builder(int estimate)

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

Parameters:

estimate - estimated array length

Returns:

a new builder instance
