Kotlin Property Getters and Setters Behind the Scenes

  • Kotlin property getters and setters are generated based on the property structure and accessors included.
  • Usage of val creates a getter and var creates both getter and setter. No backing field is generated for val properties.
  • Back to the field is used inside accessors and is required, like when an initializer is present or lateinit is used.
  • Customized accessors can be defined in Kotlin to fine-tune behavior without extra work.
  • Visibility can be adjusted for individual accessors, controlling read and write access at the method level.
  • Annotations like @JvmField and @JvmStatic impact how Kotlin properties are compiled and interact with Java code.
  • Usage of val, var, and annotations can change property behavior and visibility in Java bytecode.
  • Property mutability and annotations like @JvmField affect how Kotlin properties are seen and accessed from Java.
  • Kotlin's approach to property handling involves interactions between fields, methods, visibility, and annotations.
  • Delegated properties in Kotlin also interact with mutability and affect Java bytecode translation.
