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 classLocalVariableInstruction
- Parameters:
out
- Output stream- Throws:
java.io.IOException
-
initFromFile
protected void initFromFile(ByteSequence bytes, boolean wide) throws java.io.IOException
Read needed data (e.g. index) from file.- Overrides:
initFromFile
in classLocalVariableInstruction
- Parameters:
bytes
- byte sequence to read fromwide
- "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:LocalVariableInstruction
Long output format: <name of opcode> "["<opcode number>"]" "("<length of instruction>")" "<"< local variable index>">"- Overrides:
toString
in classLocalVariableInstruction
- Parameters:
verbose
- long/short format switch- Returns:
- mnemonic for instruction
-
setIndex
public final void setIndex(int n)
Set index of local variable.- Specified by:
setIndex
in interfaceIndexedInstruction
- Overrides:
setIndex
in classLocalVariableInstruction
- See Also:
LocalVariableInstruction.setIndexOnly(int)
-
getIncrement
public final int getIncrement()
- Returns:
- increment factor
-
setIncrement
public final void setIncrement(int c)
Set increment factor.
-
getType
public Type getType(ConstantPoolGen cp)
Description copied from class:LocalVariableInstruction
Returns the type associated with the instruction - in case of ALOAD or ASTORE Type.OBJECT is returned. This is just a bit incorrect, because ALOAD and ASTORE may work on every ReferenceType (including Type.NULL) and ASTORE may even work on a ReturnaddressType .- Specified by:
getType
in interfaceTypedInstruction
- Overrides:
getType
in classLocalVariableInstruction
- Returns:
- int type
-
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 classInstruction
- Parameters:
v
- Visitor object
