HashCode(Single[])

Returns a hash code based on the contents of the specified array.

[Android.Runtime.Register("hashCode", "([F)I", "")]
public static int HashCode (float[]? a);

[<Android.Runtime.Register("hashCode", "([F)I", "")>]
static member HashCode : single[] -> int

Parameters

a

Single[]

the array whose hash value to compute

Returns

Int32

a content-based hash code for a

Attributes

RegisterAttribute

Remarks

Returns a hash code based on the contents of the specified array. For any two float arrays a and b such that Arrays.equals(a, b), it is also the case that Arrays.hashCode(a) == Arrays.hashCode(b).

The value returned by this method is the same value that would be obtained by invoking the List#hashCode() hashCode method on a List containing a sequence of Float instances representing the elements of a in the same order. If a is null, this method returns 0.

Remarks

Returns a hash code based on the contents of the specified array. For any two long arrays a and b such that Arrays.equals(a, b), it is also the case that Arrays.hashCode(a) == Arrays.hashCode(b).

HashCode(Object[])

Returns a hash code based on the contents of the specified array.

[Android.Runtime.Register("hashCode", "([Ljava/lang/Object;)I", "")]
public static int HashCode (Java.Lang.Object[]? a);

[<Android.Runtime.Register("hashCode", "([Ljava/lang/Object;)I", "")>]
static member HashCode : Java.Lang.Object[] -> int

Parameters

a

Object[]

the array whose content-based hash code to compute

Returns

Int32

a content-based hash code for a

Attributes

RegisterAttribute

Remarks

Returns a hash code based on the contents of the specified array. If the array contains other arrays as elements, the hash code is based on their identities rather than their contents. It is therefore acceptable to invoke this method on an array that contains itself as an element, either directly or indirectly through one or more levels of arrays.

For any two arrays a and b such that Arrays.equals(a, b), it is also the case that Arrays.hashCode(a) == Arrays.hashCode(b).

The value returned by this method is equal to the value that would be returned by Arrays.asList(a).hashCode(), unless a is null, in which case 0 is returned.
