HashCode

Public / Methods

Float32

Computes a hash code for the given value.

[Pure]
public static method	Float32 (float32 value, int32 hash = 0)
type	int32
params	value		The value.
	hash		Previous hash code to combine with. Defaults to 0.
returns			The resulting hash code.

Float64

Computes a hash code for the given value.

[Pure]
public static method	Float64 (float64 value, int32 hash = 0)
type	int32
params	value		The value.
	hash		Previous hash code to combine with. Defaults to 0.
returns			The resulting hash code.

Hash

Computes a hash code for the given values.

[Pure]
public static method	Hash (int32 hash0, int32 hash1)
type	int32
params	hash0		First hash code.
	hash1		Second hash code.
returns			The resulting hash code.

Int32

Computes a hash code for the given value.

[Pure]
public static method	Int32 (int32 value, int32 hash = 0)
type	int32
params	value		The value.
	hash		Previous hash code to combine with. Defaults to 0.
returns			The resulting hash code.

Int64

Computes a hash code for the given value.

[Pure]
public static method	Int64 (int64 value, int32 hash = 0)
type	int32
params	value		The value.
	hash		Previous hash code to combine with. Defaults to 0.
returns			The resulting hash code.

Obj

Computes a hash code for the given value.

[Pure]
public static method	Obj (object value, int32 hash = 0)
type	int32
params	value		The value.
	hash		Previous hash code to combine with. Defaults to 0.
returns			The resulting hash code.

ObjRef

Computes a hash code for the given value.

[Pure]
public static method	ObjRef (object value, int32 hash = 0)
type	int32
params	value		The value.
	hash		Previous hash code to combine with. Defaults to 0.
returns			The resulting hash code.

ShallGrowHashtable

Determines whether a power-of-two sized hashtable should be grown in order to keep up good hashing performance.

public static method	ShallGrowHashtable (int32 countUsedBuckets, int32 countUsedNodes, int32 capacity)
type	bool
params	countUsedBuckets		Number of used hashtable buckets.
	countUsedNodes		Sum of number of linked nodes of all hashtable buckets.
	capacity		Capacity of the hashtable, in buckets.
returns			true if the hashtable should be grown, false if not.

Str

Computes a hash code for the given value.

[Pure]
public static method	Str (string value, int32 hash = 0)
type	int32
params	value		The value.
	hash		Previous hash code to combine with. Defaults to 0.
returns			The resulting hash code.

Remarks:

The method will always produce the same hash code for the same string value, independently of the programming language or runtime environment (e.g. DOT.NET 32-bit vs. 64-bit).
