Compares its two arguments for order.
[Android.Runtime.Register("compare", "(Ljava/lang/Object;Ljava/lang/Object;)I", "GetCompare_Ljava_lang_Object_Ljava_lang_Object_Handler:Java.Util.IComparatorInvoker, Mono.Android, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null")]
public int Compare (Java.Lang.Object? o1, Java.Lang.Object? o2);[<Android.Runtime.Register("compare", "(Ljava/lang/Object;Ljava/lang/Object;)I", "GetCompare_Ljava_lang_Object_Ljava_lang_Object_Handler:Java.Util.IComparatorInvoker, Mono.Android, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null")>]
abstract member Compare : Java.Lang.Object * Java.Lang.Object -> intParameters
- o1
- Object
the first object to be compared.
- o2
- Object
the second object to be compared.
Returns
a negative integer, zero, or a positive integer as the first argument is less than, equal to, or greater than the second.
- Attributes
Remarks
Compares its two arguments for order. Returns a negative integer, zero, or a positive integer as the first argument is less than, equal to, or greater than the second.
The implementor must ensure that Integer#signum signum(compare(x, y)) == -signum(compare(y, x)) for all x and y. (This implies that compare(x, y) must throw an exception if and only if compare(y, x) throws an exception.)
The implementor must also ensure that the relation is transitive: ((compare(x, y)>0) && (compare(y, z)>0)) implies compare(x, z)>0.
Finally, the implementor must ensure that compare(x, y)==0 implies that signum(compare(x, z))==signum(compare(y, z)) for all z.
