Method Details
-
accept
Calls 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:
acceptin classInstruction- Parameters:
v- Visitor object
-
dump
Dumps instruction as byte code to stream out.- Overrides:
dumpin classLocalVariableInstruction- Parameters:
out- Output stream- Throws:
IOException- Thrown when an I/O exception of some sort has occurred.
-
getIncrement
- Returns:
- increment factor
-
getType
Description copied from class:LocalVariableInstructionReturns the type associated with the instruction - in case of ALOAD or ASTORE Type.OBJECT is returned. This is just a bit incorrect, because ALOAD and ASTORE may work on every ReferenceType (including Type.NULL) and ASTORE may even work on a ReturnaddressType .- Specified by:
getTypein interfaceTypedInstruction- Overrides:
getTypein classLocalVariableInstruction- Returns:
- int type
-
initFromFile
Reads needed data (e.g. index) from file.- Overrides:
initFromFilein classLocalVariableInstruction- 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
-
setIncrement
Sets increment factor. -
setIndex
Sets index of local variable.- Specified by:
setIndexin interfaceIndexedInstruction- Overrides:
setIndexin classLocalVariableInstruction- See Also:
-
LocalVariableInstruction.setIndexOnly(int)
-
toString
Returns mnemonic for instruction.- Overrides:
toStringin classLocalVariableInstruction- Parameters:
verbose- long/short format switch- Returns:
- mnemonic for instruction.
