Constructor Detail

VarnodeOperation

public VarnodeOperation(PcodeOp pcodeOp,
                        Varnode[] inputValues)

Method Detail

isSimplified

public boolean isSimplified()

setSimplified

public void setSimplified(boolean simplified)

equals

public boolean equals(java.lang.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 java.lang.String toString()

Overrides:

toString in class Varnode

toString

public java.lang.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

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

isPersistant

public boolean isPersistant()

Overrides:

isPersistant in class Varnode

Returns:

is persistant

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
