- ## Constructor Details

  - ### VarnodeOperation

    public VarnodeOperation(PcodeOp pcodeOp, Varnode[] inputValues)

- ## Method Details

  - ### isSimplified

    public boolean isSimplified()

  - ### setSimplified

    public void setSimplified(boolean simplified)

  - ### equals

    public boolean equals(Object o)
    Overrides:
      `equals` in class `Varnode`

  - ### hashCode

    public int hashCode()
    Overrides:
      `hashCode` in class `Varnode`

  - ### getPCodeOp

    public PcodeOp getPCodeOp()

  - ### getInputValues

    public Varnode[] getInputValues()

  - ### toString

    public String toString()
    Overrides:
      `toString` in class `Varnode`

  - ### toString

    public String toString(Language language)
    Description copied from class: `Varnode`
    Convert this varnode to an alternate String representation based on a specified language.
    Overrides:
      `toString` in class `Varnode`
    Parameters:
      `language` - is the specified Language
    Returns:
      string representation

  - ### isAddress

    public boolean isAddress()
    Overrides:
      `isAddress` in class `Varnode`
    Returns:
      true if this varnode exists in a Memory space (vs. register etc...). Keep in mind this varnode may also correspond to a defined register if true is returned and `Varnode.isRegister()` return false. Memory-based registers may be indirectly addressed which leads to the distinction with registers within the register space.

  - ### isAddrTied

    public boolean isAddrTied()
    Overrides:
      `isAddrTied` in class `Varnode`
    Returns:
      is mapped to an address

  - ### isConstant

    public boolean isConstant()
    Overrides:
      `isConstant` in class `Varnode`
    Returns:
      true if this varnode is just a constant number

  - ### isFree

    public boolean isFree()
    Overrides:
      `isFree` in class `Varnode`

  - ### isInput

    public boolean isInput()
    Overrides:
      `isInput` in class `Varnode`
    Returns:
      is input to a pcode op

  - ### isPersistent

    public boolean isPersistent()
    Overrides:
      `isPersistent` in class `Varnode`
    Returns:
      is persistent

  - ### isRegister

    public boolean isRegister()
    Overrides:
      `isRegister` in class `Varnode`
    Returns:
      true if this varnode exists in a Register type space. If false is returned, keep in mind this varnode may still correspond to a defined register within a memory space. Memory-based registers may be indirectly addressed which leads to the distinction with registers within the register space.

  - ### isUnaffected

    public boolean isUnaffected()
    Overrides:
      `isUnaffected` in class `Varnode`

  - ### isUnique

    public boolean isUnique()
    Overrides:
      `isUnique` in class `Varnode`
    Returns:
      true if this varnode doesn't exist anywhere. A temporary variable.

  - ### trim

    public void trim()
    Description copied from class: `Varnode`
    Trim a varnode in a constant space to the correct starting offset. Constant handles may contain constants of indeterminate size. This is where the size gets fixed, i.e. we mask off the constant to its proper size. A varnode that is ends up in pcode should call this method to ensure that varnodes always contains raw data. On the other hand, varnodes in handles are allowed to have offsets that violate size restrictions.
    Overrides:
      `trim` in class `Varnode`
