the Long story short this method:
- changes:
nested.nested2.normalInner - to
["nested", "nested.nested2", "nested.nested2.normalInner"]
So it can be used to search for the param in a {@link FlattenParams} object.
Formally it changes path in "flatten" notation, to an Array of all possible keys, which could have searched property.
When skipArrayIndexes is set to true it also it takes care of the arrays, which are
separated by numbers (indexes). Then it:
- changes:
nested.0.normalInner.1 - to:
nested.normalInner
Everything because when we look for a property of a given path it can be inside a mixed property. So first, we have to find top-level mixed property, and then, step by step, find inside each of them.
