Remarks

An interface for reading the properties of an inspectable object.

PropertyReader is defined as an interface that will be called by InspectionCompanion#readProperties(Object, PropertyReader). This approach allows a client inspector to read the values of primitive properties without the overhead of instantiating a class to hold the property values for each inspection pass. If an inspectable remains unchanged between reading passes, it should be possible for a PropertyReader to avoid new allocations for subsequent reading passes.

It has separate methods for all primitive types to avoid autoboxing overhead if a concrete implementation is able to work with primitives. Implementations should be prepared to accept {null} as the value of PropertyReader#readObject(int, Object).
