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

getTypecode

public final byte getTypecode()

Returns:

numeric code for basic element type

getType

public final Type getType()

Returns:

type of constructed array

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

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

Following copied from class: de.fub.bytecode.generic.Instruction

Parameters:

bytes - byte sequence to read from

wide - "wide" instruction flag

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
