Methods

Clone()

Creates a copy of this Constraint instance.

public Constraint Clone()

Returns

Constraint

The new copy of the Constraint.

Equals(object?)

Determines whether the specified object is equal to the current object.

public override bool Equals(object? obj)

Parameters

obj object

The object to compare with the current object.

Returns

bool

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

Equals(Constraint?)

protected bool Equals(Constraint? other)

Parameters

other Constraint

Returns

bool

GetHashCode()

Serves as the default hash function.

public override int GetHashCode()

Returns

int

A hash code for the current object.

ToString()

Returns the constraint in the form "NotBefore =< Ver %lt; Before". Not safe for parsing!

public override string ToString()

Returns

string

Operators

operator ==(Constraint?, Constraint?)

Indicates whether the object on the left is equal to the object on the right.

public static bool operator ==(Constraint? left, Constraint? right)

Parameters

left Constraint

The left object

right Constraint

The right object

Returns

bool

true if the objects are equal; otherwise, false.

operator !=(Constraint?, Constraint?)

Indicates whether the object on the left is not equal to the object on the right.

public static bool operator !=(Constraint? left, Constraint? right)

Parameters

left Constraint

The left object

right Constraint

The right object

Returns

bool

true if the objects are not equal; otherwise, false.
