Question for the lenght of array in medini analyze

medini_1027657760

I would like to return the value of length of array in profiling in medini analyze.

For example, there is a value of children[]. The size of value is 15 in below image.

So, I tried to make the script with "lenght" but the value is not returned in profiling.

The script is like below.

var arraylength;
arraylength = self.children.length;
arraylength;

How can I make the script?

Best regards.

Hello Shinhun,

thanks for posting this question in this forum. Well, its not well described in the guidelines I guess. The screenshot you have posted shows the attributes and fields as they are defined by the Metamodel. There we have simple (0..1) attributes and arrays (0..*). However, at runtime the later are represented as lists that can be changed, not as unchangeable arrays. As a result, the self.children expression returns a list. The right way to get the size is to use size() instead of length:

var length = self.children.size();

// alternative: convert list to array
length = self.children.toArray().length;

Happy Scripting

Jan
