[Android.Runtime.Register("indexOfSubList", "(Ljava/util/List;Ljava/util/List;)I", "")]
public static int IndexOfSubList (System.Collections.Generic.IList<object> source, System.Collections.Generic.IList<object> target);

[<Android.Runtime.Register("indexOfSubList", "(Ljava/util/List;Ljava/util/List;)I", "")>]
static member IndexOfSubList : System.Collections.Generic.IList<obj> * System.Collections.Generic.IList<obj> -> int

Parameters

source: IList<Object>

the list in which to search for the first occurrence of target.

target: IList<Object>

the list to search for as a subList of source.

Returns

Int32

the starting position of the first occurrence of the specified target list within the specified source list, or -1 if there is no such occurrence.

Attributes: RegisterAttribute

Remarks

Returns the starting position of the first occurrence of the specified target list within the specified source list, or -1 if there is no such occurrence. More formally, returns the lowest index i such that source.subList(i, i+target.size()).equals(target), or -1 if there is no such index. (Returns -1 if target.size() > source.size())

This implementation uses the "brute force" technique of scanning over the source list, looking for a match with the target at each location in turn.
