LiteFlow provides For component since v2.9.0. Returns the number of loops. Mainly used for FOR...DO... expressions.

For the usage of FOR...DO... expressions, please refer to the chapter on Loop mode.

You can define it as follows:

<chain name="chain1">
    FOR(f).DO(THEN(a, b));
</chain>

The definition of the f node needs to inherit NodeForComponent and implement the processFor method:

@LiteflowComponent("f")
public class FCmp extends NodeForComponent {
    @Override
    public int processFor() throws Exception {
        //here to return the result of for
    }
}

See the chapter Common Components for the methods that can be overridden and the methods that can be called by the this keyword.
