Class ResourceUtils

public static Resource[] selectOutOfDateSources(ProjectComponent logTo,
                                                Resource[] source,
                                                FileNameMapper mapper,
                                                ResourceFactory targets)

tells which source files should be reprocessed based on the last modification date of target files

Parameters:

logTo - where to send (more or less) interesting output

source - array of resources bearing relative path and last modification date

mapper - filename mapper indicating how to find the target files

targets - object able to map as a resource a relative path at destination

Returns:

array containing the source files which need to be copied or processed, because the targets are out of date or do not exist

                                                long granularity)

tells which source files should be reprocessed based on the last modification date of target files

Parameters:

logTo - where to send (more or less) interesting output

source - array of resources bearing relative path and last modification date

mapper - filename mapper indicating how to find the target files

targets - object able to map as a resource a relative path at destination

granularity - The number of milliseconds leeway to give before deciding a target is out of date.

Returns:

array containing the source files which need to be copied or processed, because the targets are out of date or do not exist
