question: public static boolean ensureInlinability ( SootMethod target , Stmt toInline , SootMethod container , String modifierOptions ) { if ( ! InlinerSafetyManager . canSafelyInlineInto ( target , toInline , container ) ) { return false ; } if ( ! AccessManager . ensureAccess ( container , target , modifierOptions ) ) { return false ; } if ( ! checkSpecialInlineRestrictions ( container , target , modifierOptions ) ) { return false ; } if ( ! checkAccessRestrictions ( container , target , modifierOptions ) ) { return false ; } return true ; }
target:  Returns true if this method can be inlined at the given site. Will try as hard as it can to change things to allow inlining (modifierOptions controls what it's allowed to do: safe, unsafe and nochanges) Returns false otherwise.
