SIPUSH

SIPUSH()

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

SIPUSH

public SIPUSH(short b)

Method Detail

dump

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

Dump instruction as short code to stream out.

Overrides:

dump in class Instruction

Parameters:

out - Output stream

Throws:

java.io.IOException

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

initFromFile

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

java.io.IOException - may be thrown if the implementation needs to read data from the file

getValue

public java.lang.Number getValue()

Specified by:

getValue in interface ConstantPushInstruction

getType

public Type getType(ConstantPoolGen cp)

Specified by:

getType in interface TypedInstruction

Returns:

Type.SHORT

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
