Method Detail

selectOutOfDateSources

public static Resource[] selectOutOfDateSources(Resource[] source,
                                                FileNameMapper mapper,
                                                ResourceFactory targets)
                                         throws Exception

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

Parameters:

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array containing the source files which need to be copied or processed, because the targets are out of date or do not exist

Throws:

Exception

selectOutOfDateSources

public static Resource[] selectOutOfDateSources(Resource[] resources,
                                                FileNameMapper mapper,
                                                ResourceFactory targets,
                                                long granularity)
                                         throws Exception

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

Parameters:

resources - 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granularity - The number of milliseconds leeway to give before deciding a target is out of date.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array containing the source files which need to be copied or processed, because the targets are out of date or do not exist

Throws:

Exception
