LDC

public LDC(int index)
Method Detail

setSize

protected final void setSize()

dump

public void dump(java.io.DataOutputStream out)
          throws java.io.IOException
Dump instruction as byte code to stream out.
Overrides:
dump in class CPInstruction
Parameters:
out - Output stream

setIndex

public final void setIndex(int index)
Set the index to constant pool and adjust size.
Overrides:
setIndex in class CPInstruction
Following copied from class: org.apache.bcel.generic.CPInstruction
Parameters:
index - in constant pool.

initFromFile

protected void initFromFile(ByteSequence bytes,
                            boolean wide)
                     throws java.io.IOException
Read needed data (e.g. index) from file.
Overrides:
initFromFile in class CPInstruction
Following copied from class: org.apache.bcel.generic.CPInstruction
Parameters:
bytes - input stream
wide - wide prefix?

getValue

public java.lang.Object getValue(ConstantPoolGen cpg)

getType

public Type getType(ConstantPoolGen cpg)
Specified by:
getType in interface TypedInstruction
Overrides:
getType in class CPInstruction
Following copied from class: org.apache.bcel.generic.CPInstruction
Returns:
type related with this instruction.

getExceptions

public java.lang.Class[] getExceptions()
Specified by:
getExceptions in interface ExceptionThrower

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.
Overrides:
accept in class Instruction
Parameters:
v - Visitor object
