bool	True if the two value changes represent the same object and change, false otherwise.

Overrides

ValueType.Equals(object)

GetHashCode()

Returns a hash value computed using the item's position, old value, and new value.

Declaration

public override int GetHashCode()

Returns

Type	Description
int

Overrides

ValueType.GetHashCode()

Matches(ValueChange<T>)

Compares the two changes according to their positions and values.

Declaration

public bool Matches(ValueChange<T> other)

Parameters

Type	Name	Description
ValueChange<T>	other

Returns

Type	Description
bool	True if the two value changes represent the same change, false otherwise.

ToString()

Returns a string representing the object, including its position, old value, and new value.

Declaration

public override string ToString()

Returns

string

Overrides

ValueType.ToString()

Operators

operator ==(ValueChange<T>, ValueChange<T>)

Tests the two changes by their fields for equality.

Declaration

ValueChange<T>	left
ValueChange<T>	right

Returns

Type	Description
bool	True if all the changes are equivalent; false otherwise.

operator !=(ValueChange<T>, ValueChange<T>)

Tests the two changes by their fields for inequality.
