Direct Known Subclasses:

JavaScriptPropertyRead

public abstract class AbstractReflectiveGet
extends ReflectiveMemberAccess

This abstract class represents field (a.k.a property) reads in which the field name is not a constant, but rather a computed value. This is common in scripting languages, and so this base class is shared across all languages that need such accesses.
