IndexedObject.kt

TLDR

The IndexedObject.kt file contains a Kotlin sealed class IndexedObject with its subclasses IndexedClass, IndexedInstance, IndexedObjectArray, and IndexedPrimitiveArray. These classes represent different types of indexed objects in the Shark library.

Classes

IndexedObject

IndexedObject is a sealed class that serves as the base class for different types of indexed objects in the Shark library. It has two abstract properties: position and recordSize.

IndexedClass

IndexedClass is a subclass of IndexedObject that represents an indexed class object. It contains additional properties such as superclassId, instanceSize, and fieldsIndex.

IndexedInstance

IndexedInstance is a subclass of IndexedObject that represents an indexed instance object. It contains the classId property to identify the class of the instance.

IndexedObjectArray

IndexedObjectArray is a subclass of IndexedObject that represents an indexed object array. It contains the arrayClassId property to identify the class of the array.

IndexedPrimitiveArray

IndexedPrimitiveArray is a subclass of IndexedObject that represents an indexed primitive array. It contains the primitiveType property to identify the type of the elements in the array.

  abstract val recordSize: Long

    override val position: Long,
    val superclassId: Long,
    val instanceSize: Int,

    val fieldsIndex: Int
  ) : IndexedObject()

  class IndexedInstance(
    override val position: Long,
    val classId: Long,
    override val recordSize: Long
  ) : IndexedObject()

  class IndexedObjectArray(
    override val position: Long,
    val arrayClassId: Long,
    override val recordSize: Long
  ) : IndexedObject()

  class IndexedPrimitiveArray(
    override val position: Long,
    primitiveType: PrimitiveType,
    override val recordSize: Long
  ) : IndexedObject() {
    private val primitiveTypeOrdinal: Byte = primitiveType.ordinal.toByte()
    val primitiveType: PrimitiveType
      get() = PrimitiveType.values()[primitiveTypeOrdinal.toInt()]
  }
}
