Method Details

sorted

public static <T extends Point> List<T> sorted(List<T> input,
 int desiredBuckets)

Returns a downsampled version of the provided input list.

Notes:

• The input list must be sorted.
• This method doesn't mutate the input list or any of its elements.

The output list will have desiredBuckets + 2 elements: one per bucket plus the first and last points of the original series.

Type Parameters:

T - the type of the Point elements in the input list

Parameters:

input - the input list of Point points to downsample

desiredBuckets - the desired number of buckets for the downsampled output list

Returns:

the downsampled output list

sorted

public static <T extends Point> List<T> sorted(List<T> input,
 int inputSize,
 int desiredBuckets)

Returns a downsampled version of the provided input list.

Notes:

• The input list must be sorted.
• This method doesn't mutate the input list or any of its elements.

The output list will have desiredBuckets + 2 elements: one per bucket plus the first and last points of the original series.

Type Parameters:

T - the type of the Point elements in the input list

Parameters:

input - the input list of Point points to downsample

inputSize - the size of the input list

desiredBuckets - the desired number of buckets for the downsampled output list

Returns:

the downsampled output list
