Interface InstallationFinder

All Known Implementing Classes:

SimpleInstallationFinder

public interface InstallationFinder

Finds all the installed jobs. For example, one implementation may take an installation root directory and scan all subdirectories for job installations. Provides a map from a JobInstance to its InstallationRecord based on the structure within the installation directory. Implementations of this interface should encapsulate any custom installation structure such that the resulting InstallationRecord simply contains the locations of the files needed to control the job.
