Method Details

accept
Call corresponding visitor method(s). The order is: Call visitor methods of implemented interfaces first, then call methods according to the class hierarchy in descending order, i.e., the most specific visitXXX() call comes last.- Specified by:
accept
in classInstruction
- Parameters:
v
- Visitor object
-
dump
Dump instruction as byte code to stream out.- Overrides:
dump
in classInstruction
- Parameters:
out
- Output stream- Throws:
IOException
- Thrown when an I/O exception of some sort has occurred.
-
getIndex
public final int getIndex()- Specified by:
getIndex
in interfaceIndexedInstruction
- Returns:
- index of local variable containg the return address
-
getType
- Specified by:
getType
in interfaceTypedInstruction
- Returns:
- return address type
-
initFromFile
Read needed data (e.g. index) from file.- Overrides:
initFromFile
in classInstruction
- Parameters:
bytes
- byte sequence to read fromwide
- "wide" instruction flag- Throws:
IOException
- may be thrown if the implementation needs to read data from the file
-
setIndex
public final void setIndex(int n) Sets index of local variable containg the return address- Specified by:
setIndex
in interfaceIndexedInstruction
-
setWide
private void setWide() -
toString
Description copied from class:Instruction
Long output format: <name of opcode> "["<opcode number>"]" "("<length of instruction>")"- Overrides:
toString
in classInstruction
- Parameters:
verbose
- long/short format switch- Returns:
- mnemonic for instruction
-
