Interface IDVar

All Superinterfaces:

Comparable<IDVar>, IDElement, IDExpression, IInstructionOperand

public interface IDVar
extends IDExpression, Comparable<IDVar>

dexdec IR interface used to represent a variable (a.k.a. an identifier). Variables are factory-created by an IR context. Within a context, two variables with the same id are the same object.

Variables may be single-slot (encoded using a single register) or double-slot (encoded using a pair of registers).

Examples:

 int x = 1;
     ^  // single-slot register
 long y = 2L;
      ^  // double-slot register

Method Details

getId

int getId()

Get this variable id.

Returns:

usesSingleRegister

boolean usesSingleRegister()

Determine whether this variable uses one slot (register) only.

Returns:

usesPairOfRegisters

boolean usesPairOfRegisters()

Determine whether this variable uses two slots (registers).

Returns:

getPreferredName

String getPreferredName()

Retrieve the preferred name of this identifier, if there is one. Typically, the preferred is set to the debug name, if one is provided.

Returns:

preferred name, may be null (in which case, a name would be auto-generated)

setPreferredName

void setPreferredName(String name)

Set the optional preferred name of this identifier.

Parameters:

name - optional preferred name

duplicate

IDVar duplicate()

Pseudo-duplication. For variables, this method returns this.

Specified by:

duplicate in interface IDElement

Specified by:

duplicate in interface IDExpression

Returns:

a deep copy of this element; the type of the duplicated element should be the same as this element's type
