Method Details

getLength
int getLength()Description copied from class:Instruction
Return the length in bytes of this opcode, including all arguments. For many opcodes this method relies on an up-to-date byte index.- Overrides:
getLength
in classClassInstruction
-
getStackChange
public int getStackChange()Description copied from class:Instruction
Return the number of stack positions this instruction pushes or pops during its execution.- Overrides:
getStackChange
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
-
equalsInstruction
Two MultiANewArray instructions are equal if they have the same type and dimensions, or if the type and dimensions of either is unset.- Overrides:
equalsInstruction
in classClassInstruction
-
acceptVisit
Description copied from interface:VisitAcceptor
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.- Specified by:
acceptVisit
in interfaceVisitAcceptor
- Overrides:
acceptVisit
in classClassInstruction
-
read
Description copied from class:Instruction
Copy the given instruction data.- Overrides:
read
in classClassInstruction
-
read
Description copied from class:Instruction
