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 classInstruction
-
equalsInstruction
Description copied from class:LocalVariableInstruction
Two local variable instructions are equal if the local index they reference is equal or if either index is 0/unset.- Overrides:
equalsInstruction

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 classInstruction
-
read
Description copied from class:Instruction
Read the arguments for this opcode from the given stream. This method should be overridden by opcodes that take arguments.- Overrides:

in classInstruction
- Throws:
IOException
-
write
Description copied from class:Instruction
Write the arguments for this opcode to the given stream. This method should be overridden by opcodes that take arguments.- Overrides:
