    - - org.apache.commons.compress.harmony.unpack200.bytecode.forms.WideForm

-     public class WideForm
      extends VariableInstructionForm

  This class implements the byte code form for the wide instruction. Unlike other instructions, it can take multiple forms, depending on what is being widened.

    All Methods Instance Methods Concrete Methods
    Modifier and Type | Method and Description
    --- | ---
    `void` | `setByteCodeOperands(ByteCode byteCode, OperandManager operandManager, int codeLength)` When passed a byteCode, an OperandTable and a SegmentConstantPool, this method will set the rewrite of the byteCode appropriately.
    `protected void` | `setByteCodeOperandsFormat1(int instruction, ByteCode byteCode, OperandManager operandManager, int codeLength)` This method sets the rewrite array for the bytecode using Format 1 of the JVM spec: an opcode and two index bytes.
    `protected void` | `setByteCodeOperandsFormat2(int instruction, ByteCode byteCode, OperandManager operandManager, int codeLength)` This method sets the rewrite array for the bytecode using Format 2 of the JVM spec: an opcode, two index bytes, and two constant bytes.

          public WideForm(int opcode,
                          String name)

  - ### Method Detail

    - #### setByteCodeOperands

          public void setByteCodeOperands(ByteCode byteCode,
                                          OperandManager operandManager,
                                          int codeLength)

      Description copied from class: `ByteCodeForm`
      When passed a byteCode, an OperandTable and a SegmentConstantPool, this method will set the rewrite of the byteCode appropriately.
      Specified by:
        `setByteCodeOperands` in class `ByteCodeForm`
      Parameters:
        `byteCode` - ByteCode to be updated (!)
        `operandManager` - OperandTable from which to draw info
        `codeLength` - Length of bytes (excluding this bytecode) from the beginning of the method. Used in calculating padding for some variable-length bytecodes (such as lookupswitch, tableswitch).

    - #### setByteCodeOperandsFormat1

          protected void setByteCodeOperandsFormat1(int instruction,
                                                    ByteCode byteCode,
                                                    OperandManager operandManager,
                                                    int codeLength)

      This method sets the rewrite array for the bytecode using Format 1 of the JVM spec: an opcode and two index bytes. This is used for ?load/?store/ret
      Parameters:
        `instruction` - should be 132
        `byteCode` - the byte code whose rewrite array should be updated
        `operandManager` - the source of the operands
        `codeLength` - ignored

    - #### setByteCodeOperandsFormat2

          protected void setByteCodeOperandsFormat2(int instruction,
                                                    ByteCode byteCode,
                                                    OperandManager operandManager,
                                                    int codeLength)

      This method sets the rewrite array for the bytecode using Format 2 of the JVM spec: an opcode, two index bytes, and two constant bytes. This is used for iinc.
      Parameters:
        `instruction` - int should be 132
        `byteCode` - ByteCode whose rewrite array should be updated
        `operandManager` - OperandManager source of the operands
        `codeLength` - ignored
