PropertyReader
| android.view.inspector.PropertyReader |
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).
