public static Resource[] selectOutOfDateSources(ProjectComponent logTo,
Resource[] source,
FileNameMapper mapper,
ResourceFactory targets)
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.
public static Resource[] selectOutOfDateSources(ProjectComponent logTo,
Resource[] source,
FileNameMapper mapper,
ResourceFactory targets,
long granularity)
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before deciding a target is out of date.
public static ResourceCollection selectOutOfDateSources(ProjectComponent logTo,
ResourceCollection source,
FileNameMapper mapper,
ResourceFactory targets,
long granularity)
logTo - where to send (more or less) interesting output.source - ResourceCollection.mapper - filename mapper indicating how to find the target Resources.targets - object able to map a relative path as a Resource.granularity - The number of milliseconds leeway to give
before deciding a target is out of date.
public static ResourceCollection selectSources(ProjectComponent logTo,
ResourceCollection source,
FileNameMapper mapper,
ResourceFactory targets,
ResourceUtils.ResourceSelectorProvider selector)
logTo - where to send (more or less) interesting output.source - ResourceCollection.mapper - filename mapper indicating how to find the target Resources.targets - object able to map a relative path as a Resource.selector - returns a selector that is applied to target
files. If it selects at least one target the source will be
added to the returned collection.
