PropertyMapper

public interface PropertyMapper

android.view.inspector.PropertyMapper

An interface for mapping the string names of inspectable properties to integer identifiers. This interface is consumed by InspectionCompanion.mapProperties(PropertyMapper). Mapping properties to IDs enables quick comparisons against shadow copies of inspectable objects without performing a large number of string comparisons. Properties that derive their value from an XML attribute should provide the attribute resource ID (e.g.: R.attr.color). For runtime or generated properties properties without attribute IDs, supply Resources.ID_NULL for attributeId.
