Method Summary
Modifier and TypeMethodDescriptionvoid
acceptVisit
(BCVisitor visit) Accept a visit from aBCVisitor
, calling the appropriate methods to notify the visitor that it has entered this entity, and to provide it with the proper callbacks for each sub-entity owned by this one.boolean
equalsInstruction
(Instruction other) Two MultiANewArray instructions are equal if they have the same type and dimensions, or if the type and dimensions of either is unset.int
Return the dimensions of the array, or -1 if not set.int
Return the number of stack positions this instruction pushes or pops during its execution.setDimensions
(int dims) Set the dimensions of the array.Methods inherited from class serp.bytecode.ClassInstruction

getStackChange
public int getStackChange()Description copied from class:Instruction
Return the number of stack positions this instruction pushes or pops during its execution.- Overrides:

in classClassInstruction
- Returns:
- 0 if the stack is not affected by this instruction, a positive number if it pushes onto the stack, and a negative number if it pops from the stack
-
getDimensions
public int getDimensions()Return the dimensions of the array, or -1 if not set. -
setDimensions
Set the dimensions of the array.- Returns:
- this instruction, for method chaining
-
