Stack: ..., count -> ..., arrayref
type must be one of T_INT, T_SHORT, ...

  • Constructor Details

    • NEWARRAY

      public NEWARRAY(BasicType type)
      Constructs a NEWARRAY instruction.
      Parameters:
      type - element type of array.

    • NEWARRAY

      public NEWARRAY(byte type)
      Constructs a NEWARRAY instruction.
      Parameters:
      type - element type code.

  • Method Details

    • 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(DataOutputStream out) throws IOException
      Dumps instruction as byte code to stream out.
      Overrides:
      dump in class Instruction
      Parameters:
      out - Output stream.
      Throws:
      IOException - Thrown when an I/O exception of some sort has occurred.

    • getExceptions

      public 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()
      Gets the type of the constructed array.
      Returns:
      type of constructed array.

    • getTypecode

      public final byte getTypecode()
      Gets the type code.
      Returns:
      numeric code for basic element type.

    • initFromFile

      protected void initFromFile(ByteSequence bytes, boolean wide) throws 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:
      IOException - Thrown if the implementation needs to read data from the file

    • toString

      public 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.
