takeLast()

Remove all but the last count elements from the stream

Implementation Notes

Holds at most count number of elements in memory before emitting them once the input stream is fully exhausted. This Gatherer is not suitable for infinite streams. For a version that drops the last count elements, see dropLast().

Signature

count - The positive number of elements to keep at the end of the input stream

Examples

Limit the stream to the last 3 elements

Stream
    .of("A", "B", "C", "D", "E", "F", "G")
    .gather(Gatherers4j.takeLast(3))
    .toList();
