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: de.fub.bytecode.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: de.fub.bytecode.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: de.fub.bytecode.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
