LocalVariableInstruction
protected LocalVariableInstruction(short tag,
short c_tag,
int n)
- Parameters:
tag
- Instruction numberc_tag
- Instruction number for compact version, ALOAD_0, e.g.n
- local variable index (unsigned short)
dump
public void dump(java.io.DataOutputStream out)
throws java.io.IOException
- Dump instruction as byte code to stream out.
- Parameters:
out
- Output stream- Overrides:
- dump in class Instruction
toString
public java.lang.String toString(boolean verbose)
- Long output format:
<name of opcode> "["<opcode number>"]"
"("<length of instruction>")" "<"< local variable index>">"
- Parameters:
verbose
- long/short format switch- Returns:
- mnemonic for instruction
- Overrides:
- toString in class Instruction
initFromFile
protected void initFromFile(ByteSequence bytes,
boolean wide)
throws java.io.IOException
- Read needed data (e.g. index) from file.
PRE: (ILOAD <= tag <= ALOAD_3) || (ISTORE <= tag <= ASTORE_3)
- Overrides:
- initFromFile in class Instruction
getIndex
public final int getIndex()
- Returns:
- local variable index referred by this instruction.
setIndex
public final void setIndex(int n)
- Set the local variable index
