  - ### Method Summary

    All Methods Instance Methods Concrete Methods
    Modifier and Type | Method and Description
    --- | ---
    `void` | `accept(Visitor v)` Call corresponding visitor method(s).
    `Class<?>[]` | `getExceptions()`
    `int` | `produceStack(ConstantPoolGen cpg)` This method also gives right results for instructions whose effect on the stack depends on the constant pool entry they reference.

- - ### Constructor Detail

    - #### GETSTATIC

          public GETSTATIC(int index)

  - ### Method Detail

    - #### produceStack

          public int produceStack(ConstantPoolGen cpg)

      Description copied from class: `Instruction`
      This method also gives right results for instructions whose effect on the stack depends on the constant pool entry they reference.
      Specified by:
        `produceStack` in interface `StackProducer`
      Overrides:
        `produceStack` in class `Instruction`
      Returns:
        Number of words produced onto stack by this instruction, or Constants.UNPREDICTABLE, if this can not be computed statically

    - #### getExceptions

          public 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.
      Specified by:
        `accept` in class `Instruction`
      Parameters:
        `v` - Visitor object
