NEWARRAY

NEWARRAY()

Empty constructor needed for Instruction.readInstruction. Not to be used otherwise.

Method Detail

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, that is, the most specific visitXXX() call comes last.

Specified by:

accept in class Instruction

Parameters:

v - Visitor object.

dump

public void dump(java.io.DataOutputStream out)
          throws java.io.IOException

Dumps instruction as byte code to stream out.

Overrides:

dump in class Instruction

Parameters:

out - Output stream.

Throws:

java.io.IOException - Thrown when an I/O exception of some sort has occurred.

getExceptions

public java.lang.Class<?>[] getExceptions()

Description copied from interface: ExceptionThrower

Gets the exceptions that may be thrown by this instruction.

Specified by:

getExceptions in interface ExceptionThrower

Returns:

the exceptions that may be thrown by this instruction.

getType

public final Type getType()

Returns:

type of constructed array.

getTypecode

public final byte getTypecode()

Returns:

numeric code for basic element type.

initFromFile

protected void initFromFile(ByteSequence bytes,
                            boolean wide)
                     throws java.io.IOException

Reads needed data (for example index) from file.

Overrides:

initFromFile in class Instruction

Parameters:

bytes - byte sequence to read from.

wide - "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: Instruction

Long output format: <name of opcode> "["<opcode number>"]" "("<length of instruction>")"

Overrides:

toString in class Instruction

Parameters:

verbose - long/short format switch.

Returns:

mnemonic for instruction.
