| FrameNode | | public class FrameNode extends AbstractInsnNode (Code) | | A node that represents a stack map frame. These nodes are pseudo instruction
nodes in order to be inserted in an instruction list. In fact these nodes
must(*) be inserted just before any instruction node i that
follows an unconditionnal branch instruction such as GOTO or THROW, that is
the target of a jump instruction, or that starts an exception handler block.
The stack map frame types must describe the values of the local variables and
of the operand stack elements just before i is executed.
(*) this is mandatory only for classes whose version is greater than or
equal to
Opcodes.V1_6 V1_6 .

of this list can be Integer, String or LabelNode objects (for primitive,
reference and uninitialized types respectively - see
MethodVisitor ).

type - the type of this frame. Must be Opcodes.F_NEW forexpanded frames, or Opcodes.F_FULL,Opcodes.F_APPEND, Opcodes.F_CHOP,Opcodes.F_SAME or Opcodes.F_APPEND,Opcodes.F_SAME1 for compressed frames.
Parameters:
nLocal - number of local variables of this stack map frame.
Parameters:
local - the types of the local variables of this stack map frame.Elements of this list can be Integer, String or LabelNode objects(for primitive, reference and uninitialized types respectively -see MethodVisitor).
Parameters:
nStack - number of operand stack elements of this stack map frame.
Parameters:
stack - the types of the operand stack elements of this stack mapframe. Elements of this list can be Integer, String or LabelNodeobjects (for primitive, reference and uninitialized typesrespectively - see MethodVisitor). |
