Constructor Detail

RET

RET()

Empty constructor needed for Instruction.readInstruction. Not to be used otherwise.

RET

public RET(int index)

Method Detail

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, that is, the most specific visitXXX() call comes last.

Specified by:

accept in class Instruction

Parameters:

v - Visitor object.

dump

public void dump(java.io.DataOutputStream out)
          throws java.io.IOException

Dumps instruction as byte code to stream out.

Overrides:

dump in class Instruction

Parameters:

out - Output stream.

Throws:

java.io.IOException - Thrown when an I/O exception of some sort has occurred.

getIndex

public final int getIndex()

Description copied from interface: IndexedInstruction

Gets the index.

Specified by:

getIndex in interface IndexedInstruction

Returns:

index of local variable containg the return address.

getType

public Type getType(ConstantPoolGen cp)

Description copied from interface: TypedInstruction

Gets the type associated with this instruction.

Specified by:

getType in interface TypedInstruction

Parameters:

cp - the constant pool generator.

Returns:

return address type.

initFromFile

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

Reads needed data (for example index) from file.

Overrides:

initFromFile in class Instruction

Parameters:

bytes - byte sequence to read from.

wide - "wide" instruction flag.

Throws:

java.io.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 interface IndexedInstruction

Parameters:

n - the index.

setWide

private void setWide()

toString

public java.lang.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.
