selectVersion

public void selectVersion(ConflictResolver.ConflictContext context)
                   throws RepositoryException

Description copied from class: ConflictResolver.VersionSelector

Determines the winning node among conflicting dependencies. Implementations will usually iterate ConflictResolver.ConflictContext.getItems(), inspect ConflictResolver.ConflictItem.getNode() and eventually call ConflictResolver.ConflictContext.setWinner(ConflictResolver.ConflictItem) to deliver the winner. Failure to select a winner will automatically fail the entire conflict resolution.

Specified by:

selectVersion in class ConflictResolver.VersionSelector

Parameters:

context - The conflict context, must not be null.

Throws:

RepositoryException - If the version selection failed.
