I follow the tutorial (http://www.ibm.com/developerworks/library/j-aopwork5/)
to practise design pattern. Whilst coding adaptor patterns, I encounter a
problem. It is related to the path location.
The files sturcture in which code works fine looks as below:
sensor/TemperatureSensor.java
sensor/RadiationSensor.java
Test.java (where calls sensor classes)
adaptor/Adaptors.aj (adaptor pattern module)
adaptor/StatusSensor.java (sensor interface)
Everything resembles the tutorial and it works well. However, if I change the
files structure to following:
TemperatureSensor.java
RadiationSensor.java
Test.java (where calls sensor classes)
adaptor/Adaptors.aj (adaptor pattern module)
adaptor/StatusSensor.java (sensor interface)
In this structure I move sensors classes to the default package (the same level
as Test class)
Then when invoking ajc compiler it echos
[error] The import sensor cannot be resolved
import sensor.TemperatureSensor;
^^^^^
[error] The import sensor cannot be resolved
import sensor.RadiationSensor;
^^^^^
[error] TemperatureSensor cannot be resolved to a type
public String TemperatureSensor.getStatus(){
^^^^^^^^^^^^^^^
[error] RadiationSensor cannot be resolved to a type
public String RadiationSensor.getStatus(){
^^^^^^^^^^^^^
[error] The type TemperatureSensor must implement the inherited abstract
method StatusSensor.getStatus()
public class TemperatureSensor{
^^^^^^^^^^^^^^^^
[error] The type RadiationSensor must implement the inherited abstract method
StatusSensor.getStatus()
public class RadiationSensor{
^^^^^^^^^^^^^^
What causes this error? or How should I compile the source in order to solve
this error?
Thank you very much,
