Methods

Equals(CrossGpuBarrierStatus)

Indicates whether the current object is equal to another object of the same type.

public bool Equals(CrossGpuBarrierStatus other)

Parameters

other CrossGpuBarrierStatus

An object to compare with this object.

Returns

bool

true if the current object is equal to the other parameter; otherwise, false.

Equals(object?)

Indicates whether this instance and a specified object are equal.

public override bool Equals(object? obj)

Parameters

obj object

The object to compare with the current instance.

Returns

bool

true if obj and this instance are the same type and represent the same value; otherwise, false.

GetHashCode()

Returns the hash code for this instance.

public override int GetHashCode()

Returns

int

A 32-bit signed integer that is the hash code for this instance.
