PropertyMapper

Kotlin |Java

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.
