Class SPLIT

java.lang.Object

io.warp10.script.NamedWarpScriptFunction

io.warp10.script.functions.SPLIT

All Implemented Interfaces:

WarpScriptStackFunction

public class SPLIT
extends NamedWarpScriptFunction
implements WarpScriptStackFunction

Split a String in segments given a delimiter.

The limit parameter controls the number of times the pattern is applied and therefore affects the length of the resulting array. If the limit n is greater than zero then the pattern will be applied at most n - 1 times, the array's length will be no greater than n, and the array's last entry will contain all input beyond the last matched delimiter.
