Method Detail

getStaticSootFieldRef

protected SootFieldRef getStaticSootFieldRef(FieldReference fref)

Return a static SootFieldRef for a dexlib FieldReference.

Parameters:

item - the dexlib FieldReference.

getSootFieldRef

protected SootFieldRef getSootFieldRef(FieldReference fref)

Return a SootFieldRef for a dexlib FieldReference.

Parameters:

item - the dexlib FieldReference.

getAssignStmt

protected AssignStmt getAssignStmt(DexBody body,
                                   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.

Returns:

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

getTargetType

protected Type getTargetType(DexBody body)

Return the target type for put instructions. Putters should override this.

Parameters:

body - the body containing this instruction

introducedTypes

public java.util.Set<Type> introducedTypes()

Description copied from class: DexlibAbstractInstruction

Return the types that are be introduced by this instruction. Instructions that may introduce types should override this.
