public class ChainedDefine
extends Define

An extension to the Define function that allows chained functions to be created.

Node node = jep.parse("define('sq',seq=>seq.map(x=>x^2),'square a sequence','Function,Chained');");
Object res = jep.evaluate(node);
jep.reinitializeComponents();
node = jep.parse("[1..5] . sq()");
res = jep.evaluate(node);

* An optional fourth parameter is a comma separated list of options.

• Chained the function is a chained function seq . fun(arg)
• Chainable the function is a chainable function evaluated as seq . fun(arg) , or fun(arg,seq)
• BinarySwapped the function is a binary function with arguments swapped in a chained context fun(seq,arg) or seq . fun(arg)

Since:

4.1
