Methods
Equals(Objekt)
Určuje, zda je specifikovaný objekt rovný aktuálnímu objektu.
public override bool Equals(object obj)Parameters
obj object
srovnatelný objekt.
Returns
Výsledek rovnosti
Equals(PolygonShape)
Zkontrolujte, zda jsou objekty stejn.
protected bool Equals(PolygonShape other)Parameters
other PolygonShape
Druhý objekt.
Returns
Výsledkem je srovnání rovnosti.
GetBounds(Matrix)
