All of these methods are kind of removed:

• getBuiltinType is the same asgetTypeIdentifier ofBuiltinType andObjectType
• isNullable still exists
• getClassName only exists onObjectType
• isCollection is the equivalent of$type instanceof CollectionType
• getCollection[Key|Value]Types is the same asgetCollection[Key|Value]Type ofCollectionType

TheType ofTypeInfo is really different from the one fromPropertyInfo, so I think we might rewrite that part completely.

Or maybe redirect to the doc related to TypeInfo'sType?

Thanks, I missed those differences.
Maybe we can remove this part fromPropertyInfo Type doc as the class is deprecated and updateTypeInfo doc with appropriate methods ?

I would also not mix the TypeInfo things into the doc of PropertyInfo

This is not what theType class (fromtype-info) contains.
