public interface IPlotDataAccess
This interface forms the communications contract between the plotter classes and any possible data access layer using a class that implements this interface.
Method Summary | |
---|---|
java.util.HashMap |
retrieveData(java.lang.Object constraints)
This method will retrieve data from the data access layer using an object with any possible information and it must return a HashMap dataset understandable by the plotter. |
java.util.HashMap |
updateData(java.util.HashMap currentDataSet,
java.lang.Object constraints)
This method will update the dataset provided using an object with any possible information and it must return a HashMap dataset understandable by the plotter. |

java.util.HashMap retrieveData(java.lang.Object constraints) throws PlotterDataAccessException
constraints
- An object with constraints to be passed to the implementing class
PlotterDataAccessException
- will be thrown if the dataset could not
be generated for any reason, like database exceptions, file errors, etc.java.util.HashMap updateData(java.util.HashMap currentDataSet, java.lang.Object constraints) throws PlotterDataAccessException
currentDataSet
- The dataset to be updatedconstraints
- An object with constraints to be passed to the implementing class
