Interface ProgressCallback
- All Known Implementing Classes:
AntProgressCallback
,VerboseProgressCallback
public interface ProgressCallback
This interface can be implemented to return progress information from the file generation process.
During the execution of code generation, there are three main operations: database introspection, code generation based on the results of introspection, and then merging/saving generated files. Methods in this interface accordingly and in this order:
- introspectionStarted(int)
- (Repeatedly) startTask(String)
- generationStarted(int)
- (Repeatedly) startTask(String)
- saveStarted(int)
- (Repeatedly) startTask(String)
- done()
Periodically, the checkCancel()
method will be called to see if the
method should be canceled.
For planning purposes, the most common use case will have a ratio of 20% introspection tasks, 40% generation tasks, and 40% save tasks.

Method Details
-
introspectionStarted
default void introspectionStarted(int totalTasks) Called to note the start of the introspection phase, and to note the maximum number of startTask messages that will be sent for the introspection phase.- Parameters:
totalTasks
- the maximum number of times startTask will be called for the introspection phase.
-
generationStarted
default void generationStarted(int totalTasks) Called to note the start of the generation phase, and to note the maximum number of startTask messages that will be sent for the generation phase.- Parameters:
totalTasks
- the maximum number of times startTask will be called for the generation phase.
-
saveStarted
default void saveStarted(int totalTasks) Called to note the start of the file saving phase, and to note the maximum number of startTask messages that will be sent for the file saving phase.- Parameters:
totalTasks
- the maximum number of times startTask will be called for the file saving phase.
-
startTask
Called to denote the beginning of a save task.- Parameters:
taskName
- a descriptive name of the current work step
-
done
default void done()This method is called when all generated files have been saved. -
checkCancel
The method is called periodically during a long-running method. If the implementation throwsInterruptedException
then the method will be canceled. Any files that have already been saved will remain on the file system.- Throws:
InterruptedException
- if the operation should be halted
