Question: Is it possible to return values from an existing config?

[Osiris-Team]

Lets say I have a file called person.yml and I want to get the values for "name" and "last-name".

name: "John"
last-name: "Stamos"

Is there a way doing this with simple yaml?

[portlek]

there are getValues(boolean) and getMapValue(boolean) methods to get values of the each section.

@portlek Lets take it a step further and say that I don't know the path ("name" and "last-name") but I want to get a list or map containing all information.

[portlek]

as i said, you can get the values with getValues and getMapValues methods, you don't have to know these name or last-name section.

[Osiris-Team]

Ok great thx

[portlek]

when you use getValues(boolean) method it returns a map that looks like:

{
"name": "John",
"last-name": "Stamos"
}

@portlek Another question. Will this still work if we talk about a yml file that only exists in the memory?

[portlek]

Probably yes, the library is using MemorySection so it stores in the memory, and you will get these values from it.

@portlek Thanks for helping btw. But there is something more ^^ The map returns an object, but i need to know what object it is(List, String...). How do I do that?

[portlek]

just use instanceof which is a Java feature.

For single values you can use get(String path). If you know types you can use direct methods like getString or getInt. If you don't know the path of keys then use getValues or getMapValues.

If you know the path of keys but don't know the type of the value there are methods to check its type like isString or isInt.

Have a look to all available methods of ConfigurationSection here.

And yes, all changes are made in memory. File is only read on load and written on save. You can even have a YamlFile without any file too (entirely in memory).
