Class PropertyExtractors

java.lang.Object

org.apache.juneau.junit.bct.PropertyExtractors

public class PropertyExtractors
extends Object

Collection of standard property extractor implementations for the Bean-Centric Testing framework.

This class provides the built-in property extraction strategies that handle the most common object types and property access patterns. These extractors are automatically registered when using BasicBeanConverter.Builder.defaultSettings().

Extractor Hierarchy:

The extractors form an inheritance hierarchy for code reuse:

• PropertyExtractors.ObjectPropertyExtractor - Base class with JavaBean property access
• PropertyExtractors.ListPropertyExtractor - Extends ObjectPropertyExtractor with array/collection support
• PropertyExtractors.MapPropertyExtractor - Extends ObjectPropertyExtractor with Map key access

Execution Order:

In BasicBeanConverter, the extractors are tried in this order:

1. Custom extractors - User-registered extractors via BasicBeanConverter.Builder.addPropertyExtractor(PropertyExtractor)
2. PropertyExtractors.ObjectPropertyExtractor - JavaBean properties, fields, and methods
3. PropertyExtractors.ListPropertyExtractor - Array/collection indices and size properties
4. PropertyExtractors.MapPropertyExtractor - Map key access and size property

Property Access Strategy:

Each extractor implements a comprehensive fallback strategy for maximum compatibility:
