SIPUSH

SIPUSH()

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

SIPUSH

public SIPUSH(short b)

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 short 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.

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:

Type.SHORT.

getValue

public java.lang.Number getValue()

Description copied from interface: ConstantPushInstruction

Gets the value to push onto the stack.

Specified by:

getValue in interface ConstantPushInstruction

Returns:

the value to push onto the stack.

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

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.
