Class AbstractReflectivePut

java.lang.Object

com.ibm.wala.ssa.SSAInstruction

com.ibm.wala.ssa.ReflectiveMemberAccess

com.ibm.wala.cast.ir.ssa.AbstractReflectivePut

Direct Known Subclasses:

AstPropertyWrite

public abstract class AbstractReflectivePut
extends ReflectiveMemberAccess

This abstract class represents field (a.k.a property) writes 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.
