                         java.lang.String[] exceptions)
        Constructs a new JSRInlinerAdapter. Subclasses must not use this constructor. Instead, they must use the JSRInlinerAdapter(int, MethodVisitor, int, String, String, String, String[]) version.
        Parameters:
        methodVisitor - the method visitor to send the resulting inlined method code to, or null.
        access - the method's access flags.
        name - the method's name.
        descriptor - the method's descriptor.
        signature - the method's signature. May be null.
        exceptions - the internal names of the method's exception classes (see Type.getInternalName()). May be null.
        Throws:
        java.lang.IllegalStateException - if a subclass calls this constructor.

        methodVisitor - the method visitor to send the resulting inlined method code to, or null.
        access - the method's access flags (see Opcodes). This parameter also indicates if the method is synthetic and/or deprecated.
        name - the method's name.
        descriptor - the method's descriptor.
        signature - the method's signature. May be null.
        exceptions - the internal names of the method's exception classes (see Type.getInternalName()). May be null.

      • setComputeLimits

        public void setComputeLimits​(int maxBytes,
                             long maxOperations)
        Sets the maximum number of bytes which can be allocated, and the maximum number of "operations" which can be performed, to inline the subroutines. Operations are not formally defined but their total number is deterministic and approximatively proportional to the computation time.

        The default limits should be sufficient for any "normal" class. You only need to set new limits if visitEnd() throws a LimitExceededException on some of your classes.

        Parameters:
        maxBytes - the maximum number of bytes which can be allocated. Not all object instantiations are tracked (and garbage collection is ignored), but the most important ones are. The default value is 20MB.
        maxOperations - the maximum number of "operations" that can be performed. The default value is 100M.
