RET()

Empty constructor needed for the Class.newInstance() statement in Instruction.readInstruction(). Not to be used otherwise.

RET

public RET(int index)

Method Detail

dump

public void dump(DataOutputStream out)
          throws IOException

Dump instruction as byte code to stream out.

Overrides:

dump in class Instruction

Parameters:

out - Output stream

Throws:

IOException

setWide

private final void setWide()

initFromFile

protected void initFromFile(ByteSequence bytes,
                boolean wide)
                     throws IOException

Read needed data (e.g. index) from file.

Overrides:

initFromFile in class Instruction

Parameters:

bytes - byte sequence to read from

wide - "wide" instruction flag

Throws:

IOException

getIndex

public final int getIndex()

Specified by:

getIndex in interface IndexedInstruction

Returns:

index of local variable containg the return address

setIndex

public final void setIndex(int n)

Set index of local variable containg the return address

Specified by:

setIndex in interface IndexedInstruction

toString

public String toString(boolean verbose)

Description copied from class: Instruction

Long output format: <name of opcode> "["<opcode number>"]" "("<length of instruction>")"

Overrides:

toString in class Instruction

Parameters:

verbose - long/short format switch

Returns:

mnemonic for instruction

getType

public Type getType(ConstantPoolGen cp)

Specified by:

getType in interface TypedInstruction

Returns:

return address type

accept

public void accept(Visitor v)

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 class Instruction

Parameters:

v - Visitor object
