Class SplitOperator

java.lang.Object

org.thales.punch.libraries.punchlang.operator.SplitOperator

public class SplitOperator
extends Object

The split operator unsplit substrings separated by some delimiters and stores them in an array.

An example shows it all:

 split().on("yes;or;no").into([anarray]);
 

produces

 { "anarray" : ["yes" , "or" , "no" ] }
 

You can change the delimiters using delim(java.lang.String). For example:

 split().delim(":").on("yes:or:no").into([anarray]);
