[Soot-list] How to get the base of an InvokeExpr?

[Bernhard Berger]

Hi Sep,

InvokeExpr does not necessarily have a base object, for instance for static invokes (StaticInvokeExpr). You have to check if your expr is an instance of InstanceInvokeExpr. After casting it you can call getBas().

Cheers, Bernhard
