Constructor Detail

BIPUSH

public BIPUSH(byte b)
Push byte on stack

Method Detail

dump

public void dump(java.io.DataOutputStream out)
          throws java.io.IOException
Dump instruction as byte code to stream out.

Overrides:
dump in class Instruction
Parameters:
out - Output stream
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
java.io.IOException

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.BYTE

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
