Class VariableOffset

java.lang.Object

ghidra.program.model.listing.VariableOffset

public class VariableOffset
extends java.lang.Object

VariableOffset can be used as an operand or sub-operand representation object. The toString() method should be used to obtain the displayable representation string. This object is intended to correspond to a explicit or implicit register/stack variable reference. If an offset other than 0 is specified, the original Scalar should be specified.

Constructor Detail

VariableOffset

public VariableOffset(Variable variable,
                      long offset,
                      boolean indirect,
                      boolean dataAccess)

Constructor for an implied variable reference.

Parameters:

variable - function variable

offset - offset into variable

indirect - if true and variable data-type is a pointer, the offset is relative to underlying data-type of the pointer-type. This should generally be true for register use which would contain a structure pointer not a structure instance, whereas it would be false for stack-references.

dataAccess - true if content of variable is being read and/or written

VariableOffset

public VariableOffset(Reference ref,
                      Variable var)

Constructor for an explicit variable reference.

Parameters:

vref -

Method Detail

setReplacedElement

public void setReplacedElement(Scalar s,
                               boolean includeScalarAdjustment)

Sets the original replaced sub-operand Scalar.

Parameters:

s - scalar

includeScalarAdjustment - if true scalar adjustment will be included with object list or string representation

setReplacedElement

public void setReplacedElement(Register reg)

Sets the original replaced sub-operand Register.
