FieldInstruction

public FieldInstruction(org.jf.dexlib2.iface.instruction.Instruction instruction,
 int codeAddress)

Parameters:

instruction - the underlying dexlib instruction

codeAddress - the bytecode address of this instruction

Method Details

getStaticSootFieldRef

protected JFieldRef getStaticSootFieldRef(org.jf.dexlib2.iface.reference.FieldReference fref)

Return a static SootFieldRef for a dexlib FieldReference.

Parameters:

fref - the dexlib FieldReference.

Returns:

the JFieldRef for the given field Reference

getSootFieldRef

protected JFieldRef getSootFieldRef(org.jf.dexlib2.iface.reference.FieldReference fref)

Return a SootFieldRef for a dexlib FieldReference.

Parameters:

fref - the dexlib FieldReference.

Returns:

the JFieldRef for the given field Reference

getAssignStmt

protected JAssignStmt getAssignStmt(Local sourceValue,
 ConcreteRef instanceField)

Check if the field type equals the type of the value that will be stored in the field. A cast expression has to be introduced for the unequal case.

Parameters:

sourceValue - the local (left value) to be used in the assign statement

instanceField - the reference (right value) to be used in the assign statement

Returns:

assignment statement which hold a cast or not depending on the types of the operation
